Hope this video was useful for you! I would love to hear what you think about it in the comments :)
Have you tried it? Does it work? Really?
Doesn't compile. cannot covert "String" to "char" in initialization.
char* out_topic = arestVar.get_topic();
Even if it compiles, what it should DO?
Fabulous. Thanks for this. Just what I was looking for. Subscribed!
Nice. Just got your book. Still learning. Didn't know about the dashboard - W4GHV since '54
Hey there just want to thank you for creating videos
We learned a lot from you
Thanks for the video. you made this look very simple and easy.
great video mate. thanks, your tutorial makes it so much easier.
@Justice Sutton you just hacked your friend? Wow!! Who needs enemies.
Very informative. Thank you for posting this video.
Awesome video. Thanks for taking the time to show the world your knowledge. Its truly appreciated.
you probably dont care at all but does someone know of a tool to get back into an instagram account..?
I somehow lost my login password. I appreciate any assistance you can offer me!
@Kristopher Sean instablaster =)
thanks for the great tutorial your awesome man
Ty..soo mush for sharing this tutorial.
Great video as always!
Please make a LCD display (20x4) for MQTT topics and also an OLED display for MQTT topics, those two project would be really needed and appreciated.
great work.thanks....
How would you make it control a 2nd relay? My intention is to make a 2 plug outlet box. Great tutorial! I did it and it works perfectly.
Great videoo, thank yoou soo muuch, was exactly what i needed
Great resource, hard to find something that will do this.
Great vid thanks learned much - sadly cloud esp8266 sketch will not compile?
hello! after watchin n+1 WIFI solution, this helped me a lot to understand the internet controlling thing. thank you!
Thank you , very good .
dude you are amazing, it worked very well
Thanks!
Very cool.....................you have given me another headache LOL........thank you for sharing
Love it! Thanks for the video! :)
Hi, Can you please discuss about the aREST library that you have written? I know the concepts would be a bit advance for most of the people but that would really help and understand it better for web and mobile application developer like me. Would wait for your next video. Thank You.
Thanks for the video, but please tell what if we have more appliances to connect?
thanks!!
really interesting projects and i want to know that how the device is connected and communicating through different wifi or interner???
best,,,,,,,,Thanks
Hi, this is very interesting, and I was able to build something similar; my main question is about the power. If we want to put this installation somewhere we need to get power for the ESP and power for the relay, or for the device driven by the relay. how can we set up something with power for both ? thanks
For the ESP you'll need some external USB power adapter that you can plug to the mains electricity
thank you so much! for this video!!
what purpose have the number five , is a delay by 5 seconds ?
Victor morales delgado, no. "5" refers to pin no 5.
Stein-Erik Dahle thank you :)
Great video so when ahead and built it. Everything works OK. But when I reset the ESP (switch off then on again) I am unable to switch the relay. Is there a way of automatically reconnecting to aRest? so that I do not have to manually get into the aRest dashboard each time I power off.
super! i want to send sensor data wirelessly to esp8266 and trigger relay when a sensor value condition is true.. is it possible??
is possible to send on/off using a dashbutton from amazon!?
Hey guy do you have to set any port to open on your router for this?
HELLO SIR i have a doubt what about the device id it has be user defined i mean we have to enter manually ? any id ? or what is it ?
+Soumil Shah Hey! It means you can enter anything you wish, it's just a way of identifying your device on the network :)
I am working on the same project as of yours but i wanted to know how to connect various esp 8266 to each other in master slaves? (1:N) configuration?
+Jatin Kathuria Check my blog for more projects with the ESP8266 :)
Hey I really need help with an issue i have.
*So here is the problem.*
The sketches (doesn't matter which) I upload will go uploading till a 100%.
After this the sketch does NOT do anything at all.
I tried an empty sketch with just Serial.PrintIn("Working!") in the loop command, but no response.
I get no errors while uploading, it just goes to a 100% and says done uploading.
*My setup*
Adruino IDE
NodeMCU ESP8266-12E
All settings checked multiple times and changed but that did not solve the problem.
While uploading the light flashes till its done.
I hope ANYONE knows what this is or does. I got mine from China and i'll probably have to ask to get my money back.
Thanks for the video! Could you tell me if it's possible to control an ESP8266 in the air? (whitout router or real WiFi), I mean the ESP8266 can 'create' a network WiFi and also recieve and send data?
Merci :) !
Nice video. Does the relay board have a diode for reverse EMF protection? If not, it could potentially damage the ESP8266 when the relay is turned off.
The one I use does indeed have a protection via a diode.
Good to know. not obvious from the video.
Hello, how can i do to get its own wifi signal from de esp3266 ó 8266 ? since gonna install it in my car to start it via cellphone?
Nice video ! Can you make a video or send info on how to create my own dashboard on my own server ?
Thanks
Thanks! Indeed, that's something that would be interesting :)
I am using a nodemcu board but since the power output is 3.3v it just power up the relay and also cant turn on the relay what is the solution ?
Hi there, thanks for your tutorial. But, I want to ask you. What is different your device with nodemcu? I tried your tutorial with nodemcu but doesn't work
bernadus lokaputra same for me
@@sr05051986 Hey, maybe you find solution?? For controling relay with NODE MCU?
@ Can you show this video with app control.. control home devices anywhere in world using app
Hi, does it use a secure connection?
can u explain the same using thingspeak.
newbie here, parts list and url? btw can I use esp8266 board to control different relays wirelessly?
Check the corresponding article on our website :)
can you explain how to operate the 5v relay over nodemcu.(without logic level converter or npn trasistor)
Because nodemcu gpio output is 3.3volt
tried many times,but didn't work.
didnt work for me too
can you help?. its saying (Invalid library found in C:\Users)
Thanks for your tutorial on project ESP8266 control relay from anywhere. I found problem in uploading code as the message say " 'class a Rest' has no member named 'get topic'. Please can you help ?
Hi, make sure to update all the libraries to their latest versions we did a lot of changes recently
many thanks it works, but i click off LED on, ?
Thanks for the video I have joined your channel in the hope that I see a project similar to the one I want to do that is 8266 door sensor with an indicator on my phone so when I am in the workshop I know when the post arrives, any suggestions?
Hi Bob, thanks! I recommend checking our website for more projects: openhomeautomation.net/
@@openhomeautomation I tried your link above but just get an error not able to connect Thanks, Bob
will it work with a ceiling light that need 220v to work? thanks!
If you get some relay able to switch this high voltage you could prooably control your light
from where do we get the device id ??
hi we tried the same project our WiFi get connected but there problem like connection to mqtt failed try after 2 min can suggest me plz what go wrong ?
Is there a way of setting this up like that but controlling the relay from a python script on a raspberry pi instead of a webpage?
Sure, that will work with Python as well!
I am using Esp8266-12e when debugging I am geting : exit status 1 Error compiling for board NodeMcu 1.0 esp-12E Module
Vive la France
what if the relay two or more? thanks before
Thanks for tNice tutorials amazin tutorial! Such a helpful one
Where i can find the device i.d? please reply asap :D thank you
Thanks for this tuto! However the dahsboard.aRest.io user interface has changed and one cannot define the device ID, since it is an empty pick list!! That do not allow to enter any text with the actual device ID!!! No device ID no system working!!
how did you fix that?
exactly. Blynk is the best
Hi, congratulations for this video, but i have some questions.
I tried to conect with my ESP8266-12E, uploading direct from my PC the code in the microcontroler. But it dosen't work.
When I upload the code and press rst comes this error in monitor serial comes this error:
häüȤlìÉã¤$0xølb8ÉüÿŠH�lèˆhl$�y2xÍú................................................. (the points dosn't stop coming)
and nothing more. This result that i can't conect in aREST.
Did you know what i should do to fix it?
thanks for your attention
Rafael Rangel Szillat change your esp module it may b an error
can i use Adafruit Feather HUZZAH with ESP8266 WiFi instead>?
+ashesh sinha Sure thing!
could you do this with multiple relays and control which one turns on or turns on a sensor also if you were to do this how would you receive the data that the sensors collect via wifi or Bluetoothh
Sure, that will work fine for multiple relays, and you could also use the same project to collect data from sensors
thank you so much for answering my question i halve had a hard time find a way to make a resonably cheap home autamation systom a milion thank yous
My relay is working properly.
The maximum digital output from a ESP module is just 3.2 volt and 30 mA and how does it turn ON a Relay of Coil Voltage of 5V ?
any technical answer for this ?
Works just fine on this relay at least :)
Okay but there must be a Technical explanation for this .
are you sure there was no transistor in the Relay Module your were using ?
Raja Vigneshwaran, most relay-modules controls the relay via an optocoupler to separate it from any dangerous voltages.
Which relay exactly are you using? Is it 5V relay?
Indeed :)
How to control 18 relays which are at different locations..
from where we will get device id?? or is it on us to select id??
Hi, it's up to you to set the ID that you want :)
thanx for your precious reply
why show this massage {"message":"Requested device not found"} and my unique_id : "r56f89i"
what is API key in account ?
My module is esp 8266-01
ُSome one can help me??
Is there a way to control this with siri via homekit, but without the use of a homekit server in between ?
That'd be difficult in my opinion, but with a server running on a RPi in the middle that should be no problem !
can a RPi Zero be used or any other cheaper Pi alternative ?
I think you could run Tcp server on ESP, connect to it and control it with some own made protocols
oh ok, I have ordered a Pi Zero to be sure
i followed every step and the program uploads but when i it the reset and monitor the status only crazy symbols appear in the screen and they go on forever tried many times over and always with the same result :/
Ricardo Vieira, try changing the bps-rate (bits pr second or Baud). It'll mostly likely be 115200 bps, but sometimes other bps-rates are used.
Stein-Erik Dahle thank you I will try that
once you pulled up the software i got lost LOL
while compiling its show error that "exit status 1
Error compiling for board Generic ESP8266 Module." please send me solution
same problem please help
Same problem - cant even compile
hey thanks love it
By the way, there are 3V relays.

You can control relay with ESP8266 12E, like in this video above?
@@samot56498 SURE!!! ...I went on to connect it to my IFTTT and Google home assistant...
@@ANTHONYBOOTH Thank you very much for your answer. :D :D

Dear Sir
how to get device id
please sugess.
You define your own device ID in the code :)
After few days arest dashboard will not be worked properly
I used some of your libraries,I was able to control the relay from anywhere over the internet.Here is the problem for me,the device is responding in JSON format.What am I suppose to do to create my own dashboard dashboard without using dashboard.arest.io
I can help every body.
is it also possible to use password with the device id?
It is possible using aREST Pro :) Check the videos on th-cam.com/channels/TZOzcRUkEJNRQF-Vh9C7rw.html
but what about safety someone can hack your wifi to control your things

great work.thanks....
how can i get device ID?
You define your own device ID in the code :)
const int nodeID = ESP.getChipId();
