Successful integrated evcc

[azabold-priv]

Many thanks for these great instructions.
This enabled me to create a solution for photovoltaic surplus charging with my Solis inverter, my Easee wallbox (https://easee.com/) and evcc (https://evcc.io/en/).
My original attempt via SolisCloud was much too slow to achieve a reasonable control due to the 5-minute update interval.

If anyone is interested in integrating evcc, I have the configuration of evcc.yaml for the Solis connection below:

Thats perfect @azabold-priv thanks for sharing your work

Have you tried with the SolaX integration? You could use entity names instead of individual Modbus registers.

[azabold-priv]

Yes, I tried to integrate 'SolaX', but it didn't work.
I got the following error:
read failed: modbus: exception '2' (illegal data address), function '4'

BTW: My Inverter is Solis RHI-3P8K-HVES-5G

Where this log is from? Is that SolaX?

[azabold-priv]

Yes it is the error message from evcc when I use SolaX configuration.
