Wow, that's brilliant. I think your approach of using the case statement is wonderful. I have quite a few sketches with complex if, then clauses but they could be simplified with Case. I must try this approach. Thanks for the tip.
You are welcome! I usually do a drawing of the different states as bubbles and the state changes including the conditions for the change with arrows from one state to the other.

NP , and than the rail ways for the time zones . We stick just far enough into the Atlantic to be the first point of land in NA that gets light in the morning . we are 30min more east than Atlantic time in theory . LOL Im not 100% sure but Saint Pierre and Miquelon ( French owned islands just south of us ) are in the same time zone , so add part of France to that too. LOL
Sempre bello seguire i tuoi tutorial Andreas. Hai dato uno sguardo al lavoro che stanno facendo i ragazzi di let's control it ( con la realizzazione chiamata "mega") ? Che ne dici di lasciarci un video di recensione?
FYI, it's more than just India that has a non-hour offset: North Korea, Newfoundland, India, Iran, Afghanistan, Burma, Sri Lanka, the Marquesas, as well as parts of Australia use half-hour deviations from standard time, and some nations, such as Nepal, and some provinces, such as the Chatham Islands of New Zealand, use quarter-hour deviations.

Hello, Great Video! What do you recommend I do assuming my sampling time is every half a minute, and I would like my data samples to be time stamped and be sent to a server when WiFi is available, and to get stored in the internal RTC memory when WiFi is not available, to be sent later on. Keeping in mind the esp needs to be in deepsleep when not sampling for power issues.
Great job and great sntp library. It simplified alot my oled wristwatch code. I have only one serious problem, when it gets offline, exacly 1 hour after it starts running it resets, and as it is offline it loses the time. Do you have any tip? Or where should I look for the "bug"?
Excellent tutorial! thanks for your time. One a question: the NTP server can are any? for example for my country (Chile) is: cl.pool.ntp.org - again thanks! -
Hallo Herr Spiess! Vielen Dank für Ihre tollen Tutorials! Ich habe eine Frage zur SNTP Library. Ist es möglich einen UNIX Timestamp, den ich mir von einem ESP8266 Controller über ESPNOW sende, auf einem zweiten ESP8266 Controller zu setzen? Ich möchte mindestens zwei Controller zeitsynchron (auf Millisekunden genau) haben. Vielen Dank im Voraus.
Via ESPnow kann man sicher den Timestamp übertragen und die Uhr auf dem zweiten Board danach stellen. Ob die beiden dann im ms Bereich synchron laufen wage ich zu bezweifeln (Übertragungszeit)
Das habe ich bereits versucht. Die Übertragung per ESPNOW liegt im µs Bereich - kein Problem. Die interne Clock, bzw millis() zu verändern, ist gescheitert. configTime() setzt die interne Clock nur über den Zeitserver?
Hi Andreas, I love you videos, I have two NodeMCU, I have them "loosing" data printing on Thing Speak, and the other dont respont to Io Adafruit MQTT Command, do you recomend to put them on a fixed IP? or any idea of anything else?? Thanks.
I was impressed by your video and I tried to install both libraries(ESPDaily... and SNTPtime-master) via Arduino IDE: Sketch->Include Library->AddZipLibrary, but it said it is not a valid .zip library. The original NTPtimeESP library from video 67 did install OK. My board is a NodeMCU (ESP-12E).
The way you used does not work, because there are two independent "libraries" in the file. Just copy the two directories "ESPdailyTaskNTP-master" and "credentials" into your Arduino library folder and include your WLAN credentials in the "credentials.h" file. Then it should work.
That drift you mention is higher than in reality because of your code. Thing is that your code does something in X ms and sleep for Y ms. So you don't wake up every Y ms like you would like but every (X+Y) ms.
Great work, iam doing a project similar to yours at the moment. I need to esp.restart() the Chip every Day, is your method suitable to do that? To do that seems almost impossible to me. Right at the moment, i can read senor values, send them to ThingSpeak and display them 1602. Want to add a min max temperature saving variable what resets during the esp.reset() too. TH-cam help :D
The ESP8266 resets every time it wakes up from deep sleep. But it only can sleep for max one hour and a few minutes. If you need more, you have to create an external trigger.
Hello sir great video I have a question if I want to change the time sometime rather than changing the code can we take the input from an app and change it. If yes how can we do
@@AndreasSpiess thanks for replying. Ya we can program it but then for doing this I have to set a time also for taking input from user too. Can it happen that we can externally on and off esp from an app or something
Thanks for your interesting code. I have a battery powered window sensor and I wanted the ESP8266 to wake up once per day and transmit the battery voltage (I'm OK message). This is easy to do with your code. BUT - I wanted the ESP8266 to wake up randomly if the window was opened. I tried the reset pin/switch but it did not wake the ESP8266 up and transmit. Any ideas would be appreciated.
Martin Young You should be able to reset the device manually, but I never tried, what happens if you disconnect GPIO16 from RST and operate it manually. Did you try that?
THANK YOU ANDREAS! It is Oct 6, 2020 and I just pulled down the zip library and added it to Ubuntu Arduino IDE using the "Add .Zip Library", edited "credentials.h"and tried to compile the example but it won't compile. It says it cannot find "credentials.h" and it cannot find "SNTPtime.h". I search on github for SNTPtime.h but found nothing. Any ideas on what I did wrong? I am trying to develop a daily task to run a recirculating water pump for one hour at, say, 9am.
Some versions of the arduino ide really struggle with header files and the correct parsing of function definitions and the order in which they are parsed (if at all). The newer versions solve this issue. I had code that was correct, and the compiler failed to parse it correctly, telling me the function was undefined. Same code now works.
Hello Mr. Spiess, do you have an idea why i can not add the library? Everytime the Error says: "Angegebener Ordner/ZIP-Datei enthält keine gültige Bibliothek" which means that the ZIP inludes no valid library
You can use sntp to get your actual time and then loop till the right time arrived without sleeping. Then, you only need the sntp time library. You should be able to reduce the number of calls to the ntp time server by using the internal "time()" command, which is not very precise in the long run, but ok for the short term (below 1 hour for sure). So, you can correct the time every hour by calling ntp.
All we need now is a WiFi configurable alarm clock with a dawn simulator! Imagine this, an ESP8266 with a single button attached to an interrupt. That button would make the ESP start a web server so your could configure the alarms. After configured, it would go into deep sleep until it was time to wake up!
Great video and very helpful code. In my case, the code stops after printing 'X'. Not sure what I am doing wrong. I am novice at Arduino, will have to find a way to debug.
It's unclear what hardware configuration is required to get this to work, is it still GPIO16 and REST which have to be tied together? What is the purpose of the pin defined in the code, which is the last parameter of the function call?
Hi ! do you have a 4 relay nodemcu wifi calendar schedule to activate any of the 4 relays, and programmed days and hours ? You know, the code and the index.html, .css and .js code
Dear SIr, i am using nodemcu with sd card for data logging where i want to take the date and time in the logging with sensor value please guide for the same Thanks
Andreas after doing some testing and modifying it a bit so I can use it with wifi.manager (activated by a jumper), it may have a slight bug . It appears that wherever the code sleeps for a microsecond it hangs. I changed the three locations that state _sleepTime=1; to _sleepTime=ONE_SECOND; in RESET, COUNT, and CHECK. It does not hang anymore. It kept hanging on RESET and it did not make sense because the code looked good. I figured out what was happening when I set the scheduled time to run less than 2 minutes away (that section of code under CHECK also had a sleep for a microsecond in it). Not sure why it corrected the issue, or whether it was just due to wifi.manager.
update: da ich ein fan dieser uhr bin habe ich jetzt alles Wemos uhren auf das schweizer "sync-model" umgestellt :-) (y) thanks for the idea! ps.: dateTime = NTPch.getTime(1.0, 1); macht immer eine ausgabe auf den ser. monitor ... ist das gewünscht ?
Das mit dem Serial kann gut sein. Die library hat nicht den letzten "Schliff" und wenn die Devices irgendwo montiert sind, spielt eine Message am Serial keine Rolle ;-)
Hi Andreas, great ideas and cool video. thx for it. But sorry, I didn't get it to work. 1st: with a clean Arduino IDE Installation the file "credentials.h" is missing. So I commented it out an it brings me to the next poblem. 2nd: the function in c++ ESPDailyTaskNTP::ESPDailyTaskNTP(int hours,int minutes, double timeZone, char *mySSID, char *myPASSWORD, byte RESET_PIN){} needs a parameter timeZone - in the example sketch this parameter is missing in the function call: ESPDailyTaskNTP dailyTask(13, 9, my_SSID, my_PASSWORD, RESET_PIN); should be: ESPDailyTaskNTP dailyTask(13, 9, 1.0, my_SSID, my_PASSWORD, RESET_PIN); now it compiles an loads up to the ESP8266. (my_SSID and my_PASSWORD should be set individually) But now I'm searching for the connection to my wifi-router. Can you tell me where this should be in the code? Best regards Jörg
I'm using a esp32 to monitor temperatures and when they go above or below my setpoint it sends me a email. How can I have the esp32 send me a email once a day at a specific time so I know it's still on and working?
Hi, what if the application needs to execute only two tasks a day. For example, at 8:00 AM to turn on the light, and from 18:00 to turn off the light. I thought maybe for the second task I can create a new object of the class "ESPDailyTaskNTP dailyTask2" but where to write the code when the second task has to turn off the light. I appreciate your a hint.
These videos on the esp8266 is interesting but I would like it if the arduino business was missing. This module could be programmed using the Esplorer using a the node mcu or the simpler at commands. Esplorer is a cool and more intuitive interface for the esp8266.
There may be more efficient methods for the experienced gamer, but most of us are simply familiar with this IDE already. Personally, I appreciate that he is staying within it.
Puzzling since this channel seems to be concentrating on esp8266 stuff. I don´t like the arduino ide, it jumps all over the place in use and everything is so proprietary with the word Adafruit for example leading off ever library, makes it hard to use and read..
I like the Arduino IDE because I not only work with the ESP8266 but also with Arduino, Attiny and even sometimes STM32. When I started with ESP8266 I also tried LUA, but then it was horrible to use because it was not stable and I had to learn everything again. So I was quite happy when the Arduino IDE was ready. I think, LUA language was developped to be easier than C++. So, you are absolutely right about this. However, my videos are usually not at the "easy end" (at least, this is my aspiration). There are a few other channels which use LUA. Concerning AT commands: I like very much the concept that I do not need another MCU to build Wi-Fi enabled devices. This is probably the reason, why I did a lot with ESPs recently. I grew up when such devices were very expensiveand big and I really like this new stuff. If you watch my videos concerning the A6 module, you see, that I have to deal with AT commands from time to time...
The arduino IDE for me is not the way to go as it puts added complication to programming the esp. The arduino ide jumps around in use and I know it can be configured differently to make it your own but I think it sucks. Try the Esplorer and see what I mean. I´d be willing to bet that the arduino library's are the same coding that lua uses. If you are interested in coding learn lua and fix the bugs.
How can you make the esp8266 execute a task once every day, Without sending it to sleep the rest of the time? I need it to stay awake to perform other tasks
using the SNTPtime library I get nothing but error messages about the analog ports not being declared and the suggestion that the library is not suitable for esp8266 archtecture. Did I perhaps misunderstand something in yr video?
I have real use of this code to switch off my Wifi during nighttime (I believe it is not good to have wifi On for unnecessary radiation in the house) and esp will configure itself in the evening, as esp8266 could not connect to the internet after wifi gets switched off to which it got connected. But I always had difficulty uploading using Arduino IDE, how to do the same using PlatformIO?
@@AndreasSpiess Thanks, However, if I get the proper library and compile in IO I could easily upload on esp. Arduino IDE gives me error after successful compilation while uploading, I could not figure out it.
Helo.. I have a problem. I have air conditioner in a place where no internet. I must turn the air conditioner on every Tuesday at 8AM. The air conditioner has wifi module but this cannot help. When power lose al the settings in the AC are lost and you must program the timer again. I already copyed the IR ON command there is no problem to send it from ESP. Now I need the timer that will send the IR command every Tuesday. I like to have battery powered module...soo it must sleep a week to save the battery. What you sugest me? The 8 AM is not fixed it can be 8:10 or 9AM doesn matter. The goal is that when I will come at 4PM that the room will be hot (I dont need precise RTC). Thank you for help.
@@AndreasSpiess What about to use the ESP RTC. The actual time is not inportant...just send the IR abd sleep for a week and repet all over. If there is some minutes drift there is no problem...can the esp deepsleep a week?
Hi Andreas I have tried running your OncePerDayNTP.ino sketch but get the error message "no matching function for call to 'ESPDailyTaskNTP::ESPDailyTaskNTP(int, int, const char*&, const char*&, const uint8_t&)". Any ideas what I might have done wrong. I have commented out the #include bit (not sure how to implement this) and added "const char* my_SSID = "XYZXYZ"; const char* my_PASSWORD = "ABCABC" Best wishes Arthur
Try to delete your old version of the library and install the newest version. I added now a credentials.h file. You can also install it in your library. If not, just copy the two lines into your sketch and delete the #include credentials.h Then it should work. Otherwise come back and I help you.
Hi Andreas It works now. I have set it to 15:00 so you should get a sparkfun reading. The inclusion of the credentials.h file has shown me how to use this method. Many thanks for your help it's very much appreciated.

You find also the Spanish sbv on Github (just for this file as a test)
My only problem is with the Wifi status... Example, the only reason we really sleep a chip is to save on battery. In this case, if the Wifi happens to be down, or cannot connect for some reason, then the chip will not give up trying to connect.... thus draining the battery. We need a way to give it a # of times trying before it gives up and tries again much later.

Hallo Herr Spiess! Vielen Dank für Ihre tollen Tutorials!
Ich habe eine Frage zur SNTP Library. Ist es möglich einen UNIX Timestamp, den ich mir von einem ESP8266 Controller über ESPNOW sende, auf einem zweiten ESP8266 Controller zu setzen? Ich möchte mindestens zwei Controller zeitsynchron (auf Millisekunden genau) haben.
Vielen Dank im Voraus.
Via ESPnow kann man sicher den Timestamp übertragen und die Uhr auf dem zweiten Board danach stellen. Ob die beiden dann im ms Bereich synchron laufen wage ich zu bezweifeln (Übertragungszeit)
Das habe ich bereits versucht. Die Übertragung per ESPNOW liegt im µs Bereich - kein Problem. Die interne Clock, bzw millis() zu verändern, ist gescheitert. configTime() setzt die interne Clock nur über den Zeitserver?
Hi Andreas, I love you videos, I have two NodeMCU, I have them "loosing" data printing on Thing Speak, and the other dont respont to Io Adafruit MQTT Command, do you recomend to put them on a fixed IP? or any idea of anything else?? Thanks.
There are speed/updates per second limitations on Thingspeak. So, maybe the problem is not on your side.
I was impressed by your video and I tried to install both libraries(ESPDaily... and SNTPtime-master) via Arduino IDE: Sketch->Include Library->AddZipLibrary, but it said it is not a valid .zip library. The original NTPtimeESP library from video 67 did install OK. My board is a NodeMCU (ESP-12E).
The way you used does not work, because there are two independent "libraries" in the file. Just copy the two directories "ESPdailyTaskNTP-master" and "credentials" into your Arduino library folder and include your WLAN credentials in the "credentials.h" file. Then it should work.
I separated the two but it still says that something is wrong. :(
That drift you mention is higher than in reality because of your code. Thing is that your code does something in X ms and sleep for Y ms. So you don't wake up every Y ms like you would like but every (X+Y) ms.
I thought the drift should be corrected by calling the NTP time and adjusting the needed seconds.
Great work, iam doing a project similar to yours at the moment.
I need to esp.restart() the Chip every Day, is your method suitable to do that?
To do that seems almost impossible to me.
Right at the moment, i can read senor values, send them to ThingSpeak and display them 1602. Want to add a min max temperature saving variable what resets during the esp.reset() too.
TH-cam help :D
The ESP8266 resets every time it wakes up from deep sleep. But it only can sleep for max one hour and a few minutes. If you need more, you have to create an external trigger.
Hello sir great video I have a question if I want to change the time sometime rather than changing the code can we take the input from an app and change it. If yes how can we do
You can program anything if you want. For me I had no need the change the time, only the time zone.
@@AndreasSpiess thanks for replying. Ya we can program it but then for doing this I have to set a time also for taking input from user too. Can it happen that we can externally on and off esp from an app or something
Thanks for your interesting code. I have a battery powered window sensor and I wanted the ESP8266 to wake up once per day and transmit the battery voltage (I'm OK message). This is easy to do with your code. BUT - I wanted the ESP8266 to wake up randomly if the window was opened. I tried the reset pin/switch but it did not wake the ESP8266 up and transmit. Any ideas would be appreciated.
Martin Young You should be able to reset the device manually, but I never tried, what happens if you disconnect GPIO16 from RST and operate it manually. Did you try that?
THANK YOU ANDREAS! It is Oct 6, 2020 and I just pulled down the zip library and added it to Ubuntu Arduino IDE using the "Add .Zip Library", edited "credentials.h"and tried to compile the example but it won't compile. It says it cannot find "credentials.h" and it cannot find "SNTPtime.h". I search on github for SNTPtime.h but found nothing.
Any ideas on what I did wrong?
I am trying to develop a daily task to run a recirculating water pump for one hour at, say, 9am.
Just delete the line with the credentials.h and define the SSID and password in your sketch
Some versions of the arduino ide really struggle with header files and the correct parsing of function definitions and the order in which they are parsed (if at all). The newer versions solve this issue. I had code that was correct, and the compiler failed to parse it correctly, telling me the function was undefined. Same code now works.
Hello Mr. Spiess, do you have an idea why i can not add the library? Everytime the Error says: "Angegebener Ordner/ZIP-Datei enthält keine gültige Bibliothek"
which means that the ZIP inludes no valid library
Just copy the two folders in the .zip file to your library folder and restart Arduino IDE. Then, you should find it.
Ah ok thank you. The problem was that the Library Folder was in another Folder in the Zip file. Thank you a lot :)
Can this be used without putting it to sleep? I'm doing stuff with MQTT so it can't sleep very long, but I want it to do a thing at a specific time
You can use sntp to get your actual time and then loop till the right time arrived without sleeping. Then, you only need the sntp time library. You should be able to reduce the number of calls to the ntp time server by using the internal "time()" command, which is not very precise in the long run, but ok for the short term (below 1 hour for sure). So, you can correct the time every hour by calling ntp.
All we need now is a WiFi configurable alarm clock with a dawn simulator!
Imagine this, an ESP8266 with a single button attached to an interrupt. That button would make the ESP start a web server so your could configure the alarms. After configured, it would go into deep sleep until it was time to wake up!
This should be not to complicated project. Just add WiFi Manager (library)
I'll look into it, ESP8266 is still pretty new to me, thanks!
Great video and very helpful code. In my case, the code stops after printing 'X'. Not sure what I am doing wrong. I am novice at Arduino, will have to find a way to debug.
Unfortunately I cannot do remote debugging :-(
It's unclear what hardware configuration is required to get this to work, is it still GPIO16 and REST which have to be tied together? What is the purpose of the pin defined in the code, which is the last parameter of the function call?
1. If you want to deep sleep and automatically wake-up, you have to connect GPIO16 to RST
2. I explain hte pin at 4:10
Hi ! do you have a 4 relay nodemcu wifi calendar schedule to activate any of the 4 relays, and programmed days and hours ? You know, the code and the index.html, .css and .js code
Sorry, no
Dear SIr,
i am using nodemcu with sd card for data logging where i want to take the date and time in the logging with sensor value
please guide for the same
Thanks
I think you need the example sketch of the SD library and some time. It should not be too complicated.
Andreas after doing some testing and modifying it a bit so I can use it with wifi.manager (activated by a jumper), it may have a slight bug . It appears that wherever the code sleeps for a microsecond it hangs. I changed the three locations that state _sleepTime=1; to _sleepTime=ONE_SECOND; in RESET, COUNT, and CHECK. It does not hang anymore. It kept hanging on RESET and it did not make sense because the code looked good. I figured out what was happening when I set the scheduled time to run less than 2 minutes away (that section of code under CHECK also had a sleep for a microsecond in it). Not sure why it corrected the issue, or whether it was just due to wifi.manager.
This is an old project. If you want you can send me a pull request and I will integrate your changes into the code.
update: da ich ein fan dieser uhr bin habe ich jetzt alles Wemos uhren auf das schweizer "sync-model" umgestellt :-) (y)
thanks for the idea!
ps.: dateTime = NTPch.getTime(1.0, 1); macht immer eine ausgabe auf den ser. monitor ... ist das gewünscht ?
Das mit dem Serial kann gut sein. Die library hat nicht den letzten "Schliff" und wenn die Devices irgendwo montiert sind, spielt eine Message am Serial keine Rolle ;-)
Hi Andreas, great ideas and cool video. thx for it.
But sorry, I didn't get it to work.
1st: with a clean Arduino IDE Installation the file "credentials.h" is missing. So I commented it out an it brings me to the next poblem.
2nd: the function in c++
ESPDailyTaskNTP::ESPDailyTaskNTP(int hours,int minutes, double timeZone, char *mySSID, char *myPASSWORD, byte RESET_PIN){}
needs a parameter timeZone - in the example sketch this parameter is missing in the function call:
ESPDailyTaskNTP dailyTask(13, 9, my_SSID, my_PASSWORD, RESET_PIN);
should be: ESPDailyTaskNTP dailyTask(13, 9, 1.0, my_SSID, my_PASSWORD, RESET_PIN);
now it compiles an loads up to the ESP8266. (my_SSID and my_PASSWORD should be set individually)
But now I'm searching for the connection to my wifi-router. Can you tell me where this should be in the code?
Best regards
Jörg
just add #define myPassword "xxx" and #define mySSID "yyy". Xxx and yyy are your credentials. Or replace mySSID and myPASSWORD with your credentials.
Dear Sir,
i have made date logger the data is comming but i need date and time for data to be record.
pl help for that.
Thanks
To get date and time you can use any NTP library. You find a few of them in the Arduino IDE
i can't seem to include the sntp library any help?
Now it should work. Download it again.
I'm using a esp32 to monitor temperatures and when they go above or below my setpoint it sends me a email. How can I have the esp32 send me a email once a day at a specific time so I know it's still on and working?
You have to know time and then select a time to send the mail, I assume.
Sir I to play songs according to the time.Please help me i didn't understand what time unit i put in code.
I am sure you will find it out yourself. and by asking Google.
is it possible to use it with an ehternet shield instead of WIFI?
+kris maussen I think so
Hi, what if the application needs to execute only two tasks a day. For example, at 8:00 AM to turn on the light, and from 18:00 to turn off the light. I thought maybe for the second task I can create a new object of the class "ESPDailyTaskNTP dailyTask2" but where to write the code when the second task has to turn off the light. I appreciate your a hint.
Then you have to write your own code. This sketch can only do one per day.
I see. I am almost done with my own code. Thanks a lot.
These videos on the esp8266 is interesting but I would like it if the arduino business was missing. This module could be programmed using the Esplorer using a the node mcu or the simpler at commands. Esplorer is a cool and more intuitive interface for the esp8266.
There may be more efficient methods for the experienced gamer, but most of us are simply familiar with this IDE already. Personally, I appreciate that he is staying within it.
Puzzling since this channel seems to be concentrating on esp8266 stuff. I don´t like the arduino ide, it jumps all over the place in use and everything is so proprietary with the word Adafruit for example leading off ever library, makes it hard to use and read..
I like the Arduino IDE because I not only work with the ESP8266 but also with Arduino, Attiny and even sometimes STM32. When I started with ESP8266 I also tried LUA, but then it was horrible to use because it was not stable and I had to learn everything again. So I was quite happy when the Arduino IDE was ready.
I think, LUA language was developped to be easier than C++. So, you are absolutely right about this. However, my videos are usually not at the "easy end" (at least, this is my aspiration). There are a few other channels which use LUA.
Concerning AT commands: I like very much the concept that I do not need another MCU to build Wi-Fi enabled devices. This is probably the reason, why I did a lot with ESPs recently. I grew up when such devices were very expensiveand big and I really like this new stuff. If you watch my videos concerning the A6 module, you see, that I have to deal with AT commands from time to time...
Andreas Spiess Yeah, they just don't make lipo-powered Wifi microcontrollers running off of NTP servers like they used to in the 60s :P
The arduino IDE for me is not the way to go as it puts added complication to programming the esp. The arduino ide jumps around in use and I know it can be configured differently to make it your own but I think it sucks. Try the Esplorer and see what I mean. I´d be willing to bet that the arduino library's are the same coding that lua uses. If you are interested in coding learn lua and fix the bugs.
How can you make the esp8266 execute a task once every day, Without sending it to sleep the rest of the time? I need it to stay awake to perform other tasks
You can get NTP time once in a while and compare it with the desired time. There are a few libraries around for that, including one on my Github.
using the SNTPtime library I get nothing but error messages about the analog ports not being declared and the suggestion that the library is not suitable for esp8266 archtecture. Did I perhaps misunderstand something in yr video?
Shouldn't happen. Did you use the library from my github?
yes I did
Did you choose the right (ESP) board? Maybe you post the error messages here and we have a look at it.
yes the general esp board. I will try again and see what i get. Thanks for your reply and thanks for yr great videos
I have real use of this code to switch off my Wifi during nighttime (I believe it is not good to have wifi On for unnecessary radiation in the house) and esp will configure itself in the evening, as esp8266 could not connect to the internet after wifi gets switched off to which it got connected. But I always had difficulty uploading using Arduino IDE, how to do the same using PlatformIO?
If you have problems with uploading, you will have it also with PIO
@@AndreasSpiess Thanks, However, if I get the proper library and compile in IO I could easily upload on esp. Arduino IDE gives me error after successful compilation while uploading, I could not figure out it.
Does not contain valid library?.... How do I add it to arduino?
It should work now.
Helo.. I have a problem. I have air conditioner in a place where no internet. I must turn the air conditioner on every Tuesday at 8AM. The air conditioner has wifi module but this cannot help. When power lose al the settings in the AC are lost and you must program the timer again. I already copyed the IR ON command there is no problem to send it from ESP. Now I need the timer that will send the IR command every Tuesday. I like to have battery powered module...soo it must sleep a week to save the battery. What you sugest me? The 8 AM is not fixed it can be 8:10 or 9AM doesn matter. The goal is that when I will come at 4PM that the room will be hot (I dont need precise RTC). Thank you for help.
Maybe you use an RTC module to switch the power of the ESP on. You find them on aliexpress
@@AndreasSpiess What about to use the ESP RTC. The actual time is not inportant...just send the IR abd sleep for a week and repet all over. If there is some minutes drift there is no problem...can the esp deepsleep a week?
The ESP8266 can only deepsleep for a little more than 1 hour.
Hi Andreas
I have tried running your OncePerDayNTP.ino sketch but get the error message "no matching function for call to 'ESPDailyTaskNTP::ESPDailyTaskNTP(int, int, const char*&, const char*&, const uint8_t&)". Any ideas what I might have done wrong. I have commented out the #include bit (not sure how to implement this) and added "const char* my_SSID = "XYZXYZ"; const char* my_PASSWORD = "ABCABC"
Best wishes
Arthur
Try to delete your old version of the library and install the newest version. I added now a credentials.h file. You can also install it in your library. If not, just copy the two lines into your sketch and delete the #include credentials.h
Then it should work. Otherwise come back and I help you.
Hi Andreas
It works now. I have set it to 15:00 so you should get a sparkfun reading. The inclusion of the credentials.h file has shown me how to use this method.
Many thanks for your help it's very much appreciated.
You are welcome! I have no fun if my viewers are not able to use my code. It is much more fun if it works. ;-) I will check at 15:00. Which time zone did you use?
I checked, but did not get your entry at sparkfun. So, something did not work. Did you check your serial monitor?
Many thanks for checking. It's connected to a power supply and an OLED (s400740077.websitehome.co.uk/shen/2016-08-15%2017.47.57.jpg) so I do not have any serial monitor feedback. I need to write the code to drive the OLED so I can see what it's doing. I will let you know when I have completed it.
very nice tutorial , only stuck on one part , can you please help me with this been busy for days now : exit status 1
no matching function for call to 'ESPDailyTaskNTP::ESPDailyTaskNTP(int, int, double, const char [12], const char [13], const uint8_t&)'
I changed the credentials from #define to char. Now it should work. Please install the newest version of the library again.
@@AndreasSpiess thank you very much gonna do that
@@AndreasSpiess i have the same problem and i've changed credentials from #define to char. But i can't get it to work i'm getting error: expected initializer before string constant

well sorry mby i'm just stupid whriting code is something new for me and i can't wrap my head around everything yet
I can't add the library. Tried multiple ways. :(
Now you should be able to import it with the Arduino IDE
Keep being awesome, Andreas.
How can I adapt this to run multiple times in a day?
This is not easy. You have to calculate the time till the next "alarm" and steer the sleeping accordingly.
Andreas Spiess Oh okay, thanks for the video though! Will definitely help me in figuring this out.
:-)
Please can upload the subtitles, i will tried translate to spanish with your tutorial en video #132. Thanks
Thank you very much for your offer! You find the English script now on Github. As a test, I uploaded the Spanish translation from Google Translate. Please have a look at it and tell me, if you
- are able to edit the subtitles
- and whether it was a help for you.
I test a program which, at the end, should help us for the translations.
You find also the Spanish sbv on Github (just for this file as a test)
OK, tonight hope revise the archive with in spanish uploaded, see that it's okay with some details; i hope it´s helps.
Would it be possible to do the changes also in TH-cam translation functionality? I am just curious.
I already tried it, and is like a "Google translator in live", work but is translation "standard" of robot, do you me understand?
Unfortunately, I did not understand correctly.
My only problem is with the Wifi status... Example, the only reason we really sleep a chip is to save on battery. In this case, if the Wifi happens to be down, or cannot connect for some reason, then the chip will not give up trying to connect.... thus draining the battery. We need a way to give it a # of times trying before it gives up and tries again much later.
I think this should be possible by limiting the number of tries or the time it tries to connect to the internet.
supi, die beiden filme zum thema zeit !!!...
doch leider mag das beispiel OncePerDay example for ESP8266 hier nicht "arbeiten" .. die erste lib + demo ist ok.
Was genau ist das Problem? Vielleicht finden wir eine Lösung und ich kann den Code verbessern.
habe mal die fehlermeldung von OncePerDayNTP kopiert , alle deine libs sind aktuell eingepflegt und das "sntp beispiel funzt auch .. hier reichen meine kenntnisse nicht zum beurteilen des fehlers..
danke !
