Thank you Daniel, very interesting.
Excellent project 👍
Great job!
Thanks a lot.
Brilliant!!
Thanks
Excellent, like always thanks a lot. Really useful, I was thinking to buy the emonPi but the number of sensors are limited by two and even with the EmonTx is limited to 6 and thats all ... Grafana will present data really well at the end
very useful
Genius!!!
I like your theme, wish you could help me make an interface like this !!!
Hey D hows the solar system doing? Can you give us an update?
Hi, I have a power meter but it does not mentioned the protocol on the manual user, only RS485 port. How can I read data from device ? Could suggest me the idea
Hi I learning a lot of staff from you. I try the code that you mention on Arduino and for me is not working any advice? thank you
Excellent videos... learning a lot of staff from you.The InfluxDB, is that a IOT Platform or a Dashboard? Is where you can see the monitoring of the meters or you visualise them in another platform?Thanks
Thanks, InfluxDB is a database that store Time series data. I use that to store data for visualization. To visualize the data I use merely Grafana or other tools from the Tickstack.
So Grafana does not store data, is just visualisation for dashboards?On my system I will be using the ESP8266 with MQTT that will trigger an SSR for the heater. I would like now to visualise my system over the cloud but at the same moment also keep historical data. Thought to link the Thingboard to the ESP82 ? Is that a good set up?Thanks
Thank for your time and effort. I have a few questions. On your video you tested the sdm with one phase only. Did you go on to test the single phase with a higher current draw and did all the parameters have readings?
Also where I am is 110/220 50 Hz. Split phase. If I connect just two phases and neutral would the meter work ok.
Lastly can the sdm 630 work with ct.
Thanks again
The sdm dont dont do Ct. No it need neutral and yes it works. In My videos you can see that i use 4 of Them. Thanks
Successfully sdm230, thanks Daniel
Did you use a 120 Ohm Resistor for terminating the modbus?
Is it needed when using only one SDM230?
@ yes
Very interesting! I would like to read also my powermeter from my solarcells. Could I get the sketch you used for Serial Modbus RTU to get data out of the SDM meters? I bought the TTL to RS485 converter because I had problems with the USB converter.
You can find it on Github via the links. Or if you only have 1 meter its easier to run tasmota!
@@DIYTechRepairs Thank you, I found the link to daromer2/SmartHome. There are alot of lib's. I want to read out 4 modbus RTU powermeter by rs485. Finally the data will be sent by mqtt. My first goal would be to be able to read the modbusPowermeter. Would ESP8266CO2PM25.ino would be the one?
@@josephtanner248 THe code i used use alot of old libraries so its a big mess to get going. I tried recompile it with newer but never got it working im afraid
Here in the UK we're not allowed to do anything in the fuse box (consumer unit) unless you are qualified - that's the official line ... ;-)
same in australia
Its same here. Unless you have approval you are not allowed to do any changes without someone approving it! So as always stay legal :)
@Mircea your not approved to open the box here and add anything . Yes Clamp on outside is ok but sdm is not a Clamp.....
Yes, I mean a power meter, my inverter doesn't have a power measuring LCD screen and calibration buttons like some other inverters, but it has a WiFi adapter that plugs into the RS485 port, however the This parameter updates every 5 minutes, so I see you doing this or I plan to replace what is
Ok. The sdm type meters can be polled very very often. It updates many Times per second.
I want to know where to buy the switches you talk about in your video on ATS???
On Ebay? :) Which One of em?
Hello DIY I've been watching you for years love your knowledge! Quick question I got a hold of your valence 12v batteries 4 of them! I only charge them to 13.2 volts they don't seem to like anything higher? I took 1 apart like you did in your video and each individual cell reads lishen valence 3.2v is this the maximum charge each cell can handle if so I would only be able to charge to 12.8 volts max because these batteries are in 4s right? They look identical to the black valence batteries you have. Please help me out with some advice I don't want to ruin the batteries, I just want to know is it ok to charge each cell past 3.2v if so what do you recommend? They are old batteries but they work fine so far! They say 14.6 volts max on top of the actual battery does this mean I can charge them to 14.6 that would be nice but I'm afraid to go past 13.2 I don't want to blow them up please help
3.3v is nominal. Max Charge is 3.6 or 3.65v. i Charge max to 3.5
Hi! Very interesting video! But the TTL => RS485 converter you use is not isolated. Are the modbus terminals of the SDM630 galvanically separated from the mains? Is that safe enough to trust? I can't find any safety data in this on the internet. So if anything goes wrong......will everything be connected to the mains which is hooked up to your ESP32?
I got 4*630 connected on same modbus so i would Guess they are isolated.
@@DIYTechRepairs sounds reasonable!
Sketch Sorry, thank you
Oh, thank you for the reply, unfortunately, I want to get the inverter's data out for monitoring whenever needed.
This is not about inverter data but electricity meters ;)
Just a question. Why modbus? Why not Ethernet? Would it a lot of cost to have Ethernet on ESP32 for example? Or is it more about worry of having extra bulkier cables and switches, where modbus can be done with a lot less cables and no switches, and just some bigbanging?
Edit: Never mind, sdm230 already supports modbus / rs485, so it was obvious choice.
The sdm dont do ethernet. They do modbus. And wifi i have everywhere
Nice work! What's the refresh rate of the data you get from SDM?
I poll every 2 seconds.
@@DIYTechRepairs what's the highest possible sampling rate? every half second?
@@ssl2928 dont know but the answer is in the manual. Its high... Many many Times per second
HEya, is modbus the same as IEC 62053-1 (S0) ? I'de like to connect this solution to a ABB OD4165 to measure but i'm not sure if it will work with it. symmetron.gr/uploads/ABB_ODIN4165_ODIN4110.pdf
Any MPP you can recomend for lithium ion battery with wifi monitoring?
Dont know of any thta do that nativly
Daniel, du styrer for vildt
I need to find a cheap easy way to monitor remotely the electron harvesting. from my 2 charge controllers . and batt voltage , current, and basically what's going on. Batt temp would be nice. The actual cell temp. Since I'm using lithium ion. I have them arranged in 100 cell packs. I'd like to have a couple temp sensors in each pack. In case of a bad cell or just hot or cold weather. It does get 100 degees F here and below zero! I'd like keeping up with them. They aren't cheap. Have a idea of how I could do this easily??
Batrium is One way. Or build with Arduino or esp
Can i use the with M-Bus? or do i need to convert from M-BUS to Mod-Bus first?
Not sure. M bus and modbus are different things as im aware but never worked with M-Bus myself. I was under impression Mbus is for meters in generall meanwhile Modbus is more like industrial PLC and meters like the SDM series
Hi, your website does not appear to be responding. I wanted to go there to get more details on the code for this project. I’m new to this, have the SDM installed in an ev charger system and wanted to record charging data to monitor the costs of charging over time.
Up again!
Hi, I compiled a lot of errors with the arduino IDE, although I have inserted all the necessary libraries, can you help me compile it to a .bin file?
They have changed alot of libs and therefore the code i have up doesnt work very well any more. I had same issues first time i compiled it. Some day... when i have time... i will revisit it and sort it but dont have that time today im afraid
How do you get the code from the github link onto the esp8266?
Arduino ide
Hi, you're my inspiration. But I am not able to flash my esp8266 nodemcu. Arduino IDE returns many bugs. Missing files etc. Could you be so kind and share some instructions on how to do it? Thanks.
That version is difficullt to get to work. I need to redo the code 100% im afraid
@@DIYTechRepairs Thanks, Daniel. I will looking forward.
Did you sell the locost?
Its Still in My garage
I've tried to flash your eastron sourcecode on my esp8266 nodemcu but theres just shown last seen date, mac adress and so on.
How can i import the registers in my iobroker ?
My rs485 modul is not blinking on tx or rx.
Do i have to modyfi some files to show the registers ?
Ive try that for 3 days, but i can't find some solutions :(
I have 2 sdm360 meters
One of that have the adress 001 and the other have 002.
120ohm resistor is on the last SDM.
You need to have a working connection. Do you have that? Have you configured wifi?
@@DIYTechRepairs yes wifi is configured and connected, both leds on D5 and D6 are on.
The blue led on the nodemcu is blinking.
those modbus are really expensive can you do the same with sonoff?
Yes but not realy for mains nor that accurate. I have videos about sonoff too
have you ever tested cheap chinese ones from ebay for? AC Power Meter Energy Meter RS485 Modbus 220V
@@CrAzYDr1veR One phase cost fraction of 3phase. Check sdm120
CrAzYDr1veR Btw do you got a link for one you have in mind?
Your example node-red flow won't import
Had to link it in instead. It didnt work to have it on the webpage....
Thanks Daniel
Is this going to work with esp32?
If you rebuiöd the software yes
Awg for the silicon wires?
Which ones? Choose wires accordingly to max current.
