Hello.

Maybe will be useful for somebody.

https://github.com/MFxMF/SDM630-Modbus

In total are 88 parameters mapped.

Great work! Thank you!

Thank you excellent info, just what I need.

But i Have a mayor question: I need to connect the SM630 with RS485 to my raspberry so I bought a TCP232-204 rs485-etehrnet gateway. But what steps do I need to do to get domoticz to connect to the SDM630 ?

I have been reading on this forum for hours but can't find the answer

I am also working on this problem right now. There are two options:

Option 1: Use tool like socat that allows you to make a virtual serial port (ex.:/dev/ttyVir0) and bind it to the ethernet gateway. I couldn't make it work...

Option 2: Since the library used in the plugin is minimalmodbus it doesn't support modbus tcp, a new plugin should be written. I am currently trying to write one however, my python experience is not fantastic but I am slowly getting there.

It is possible to connect to SDM630 wirelessly? Maybe ESP8266? Probably some kind of solution would be RPi Zero W, and second Domoticz.

UPDATE I see there is solution with ESP8266.

Hi, thank you for sharing your code.
Can i use the SDM630 in Domoticz in combinatin with solar energy. So the kWh meter counts back or minus in the Domoticz logs?

[Odouch]

Could you use HF2211 in conjunction with SDM630?

[Odouch]

Has anyone tried ESP32 + SDM630 + DomotiCZ?

Have you found a solution for ESP8266 and SDM?

I tried ESPEasy with test plugin, and it didn't work very well. It offers possibility to read only 4 registers, and i do not see option to send them to different IDXs. Tried also Tasmota, and it reads a lot more, but again i don't know how to send those readed values to specific IDXs. Currently i am working on code to send values choosen by me to specific IDXs just by HTTP GET request to Domoticz. My SDM630 is not connected to main wires, so i am testing this with only 1 phase connected. You can look at the Reaper7 SDM library on Github. This library is also used in ESPEasy, and Tasmota.

Good day,
I'm a complete beginner.
Can't use this solution?

It took me a while but I found out that the cheap Chinese RS485 to USB converter (as shown on the pictures of the writer of this script) seems to work with the SDM630 and raspberry Pi (Domoticz), but in fact it doesn't. It is totally not stable and causes GUI freezes every week.
Since I replaced this adapter with a FTDI based one it really works perfectly without any hangups at all!

I just wanted to share that with you.

hi
I have DOMOTICZ2021.1 (build 13360) and SDM 630 modbus V2
I have a problem with starting the plugin
I have no choice of COM port

i installed: pyserial, minimalmodbus

[kaziormirek]

i solved my problem
in /boot/config.txt
add in last line enable_uart=1


[all]
#dtoverlay=vc4-fkms-v3d
enable_uart=1

Hi,

The plugin is perfect, but since the update of stable version 2021.1, the power consumption from power is not working properly. Does anyone know how to fix this ?

The Total Power Meter type shows correct power but negative or zero power consumption values.

For example the device from this line:

if 88 not in Devices:
Domoticz.Device(Name="Total Power Meter", Unit=88,TypeName="General",Subtype=0x1D,Used=0).Create()

Does anyone have experience with this ?

Hello,
Thanks for your code, but I have a problem.
I have 2 Eastron SDM630-Modbus V2 and I would like to daisy chain them and be able to loop over them in order to retrieve MQTT data via node-red.
Can you tell me if this is feasible and if so, do you have any code that allows to do it?
I thank you in advance.
