Solaredge Modbus TCP not working

[MickazNL]

Really love this docker image so far!

I'm trying to get Solaredge Modbus TCP working but the connection is throwing connection refused:

Error loading data from modbus Error: connect ECONNREFUSED 192.168.222.241:1502 at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1137:16) { errno: -111, code: 'ECONNREFUSED', syscall: 'connect', address: '192.168.222.241', port: 1502 }

My docker image is set up like this:

sudo docker run -it
--name=smartmeter
--restart=unless-stopped
--network=host
-e TZ=Europe/Amsterdam
-e SMARTMETER_SOCKET=192.168.222.245:23
-e SMARTMETER_mqtt-url=mqtt://localhost:8889
-e SMARTMETER_mqtt-topic=diy/smartmeter
-e SMARTMETER_mqtt-discovery=true
-e SMARTMETER_debug=true
-e SMARTMETER_sunspec-modbus=192.168.222.241
-e SMARTMETER_sunspec-modbus-port=1502
svrooij/smartmeter:latest

Ip and Port are correct (Solaredge uses port 1502 for modbus) the Hacs Solaredge modbus integration is also working for me.

Modbus is some what picky, mine uses a different port. And I had to turn it on at the inverter and connect for the first time within 120 seconds.

And modbus is a system where only one client can connect at the same time.

Thanks for the reply, I have that part working (which was also a hassle haha) I'm able to get the data extracted off the inverter with other software.

As we speak i'm building a modbus to mqtt in node red which is able to get the data:
