Use growatt2mqtt for evcc about growatt2mqtt HOT 3 OPEN

Thank you very much for effort and quick reply!!!
I am very happy with your software! It is running since weeks w/o problems.
With your software I have robust values (just in time!) to use it for my Home Assistant activities.
If it is not possible to use the access of growatt2mqtt to evcc, I will try to use the mqtt data in evcc.

OK, after reading about this page for 15-20 minutes, it looks like this software can read modbus directly. Ideally you don't even need my converter at all. You can plug an RS485 to USB converter into the computer/SBC this software is running on and connect the A/B lines to Growatt directly. And it will read the data straight from the inverter. You can see Growatt examples in their page. Remember RS485 can travel few hundred meters without any problems.

Or you can get a modbus RS485 to TCP gateway, and use the TCP example. I would try either of these routes and it will be a direct communication between evcc and the inverter.

As far as I can see, these examples support some generic Growatt Hybrid inverter and TL-XH series, so if you have one of those it will work. But they don't seem to have a template for other models.

I don't think it is possible. I have seen modbus client implementation for the ESP, but a modbus master.
The only option I can think about is a modbus RS485 to TCP gateway and through that evcc and homeassistant could read your inverter as well.
