Add support for Eastron SDM Energy Meters in Homey Pro. [image] Eastron | Homey Advanced Energy Monitoring with DIN Rail Meters over Modbus TCP [Afbeelding met tekst, elektronica, machine Door AI gegenereerde inhoud is mogelijk onjuist.] After 15 years of…

I have no experience with the USR-DR134, is the slave ID (client) correct? Default is 1 for the SDM630 (I changed that to 2 as my Growatt inverter is also 1 and they are on the same bus).

Yes, both client IDs are set the same on the SDM630 and on the TCP gateway, but I still can’t get it to work. Tomorrow I’ll test the gateway with one of my Growatt inverters. If that works, I’ll know the issue is with the Eastron meter.

I am still in doubt because I am not sure if this device is the only one on that phase… Because if my other electric devices also go via this phase it is not worth measuring this… I want to know my heatpump energy usage only, ultimately which part derives from solar panels and which part from the ne…

Not sure on what exact settings you need for the Eastrom SDM630, but the baud rate seems a bit high, I suggest starting with 9600 and see what happens. Also, I see port 26 and 23 used, did you set those values? I would expect to see 502 there. These are my settings for a similar waveshare device c…

Thanks @DaneedeKruyff , not yet successful… changed baud rate, port (router is limited with these settings)also changed work mode: [IMG_6693]

Well, let’s take a closer look. What are the other options/combinations for Work mode?
