No data received in domoticz

[artstam]

I just have an new solaredge inverter installed and i activated the modbus tcp (WIFI). Installation in domoticz was no problem but i can't receive any data. I got the following log:

2023-10-22 11:03:40.016 Solaredge: Pushing 'onHeartbeatCallback' on to queue

What can i do to solve the problem?

Het @artstam,

Are you sure that the portnumber is correct?
SolarEdge seems to be using different ports for particular inverters.
My inverter is using port 502, but I have also seen reports of port 1502 and 11502.

If you are sure the port is correct, did you try other values for the "Inverter Modbus device address" setting?

[artstam]

Portnumber double checked and device addres =1 and i tried several others.

Two additional questions:

• I use the IP-adres from the Solaredge on my network. If i go directly via a webbrowser to this adres then i get information of the Solaredge. Is this the IP-adres i should use?
• My Solaredge is connected via the Wifi of the Solaredge to my router. Is this ok or should i use the Lan RJ-45 connection of the Solaredge?

Are you sure that modbus is enabled on the inverter?

[addiejanssen]

There's one more topic here in the discussions where somebody reported that it started to work after a software update.
I don't know if it is possible to get data via modbus over wifi from all the types of inverters Solaredge has.

[artstam]

The firmware is up to date and according to Solaredge support the modbus should work with wifi. But it does not work.

I then connected the solaredge via Lan cable and it works perfectly!
