Template Serial Battery

[RFDarter]

It would be nice if we could have a template serial battery that will not directly connect to an bms but instead via USB to a esp32 or similar.

That way we could aggregate multiple batterys and implement a charge logic on the esp32 instead of the config file in the venus os.

Like we can do with the mqtt-battery

Feel free to develop an ESP32 software and then write a battery driver for this driver. In my eyes a lot of work for something that already works with dbus-serialbattery. No ESP32 needed.

Doing it with esphome it has a lot more Potential than doing it in a config file on the venus os.

Ease of use wozld be the big one.
Just messing with the config on the venus os once and to the rest via a web interface.

Changing the current limit and discharge current limit via a mobile phone on a Web interface.

Possibility to include it into home assistant and automating the limits.

Just to name a few.

Would you be willing to merge my battery driver if I write one?

[mr-manuel]

Sure, if you provide the whole documentation end needed ESP files. Then it's a driver like bms/esphome.py.
