Since March 2023 we have at home a PV-System from AlphaESS.\ Since years I'm using Home Assistant for my smarthome and tracking of all my entities in my home.\ So the idea was to integrate the AlphaESS system to HomeAssistant. \ The official API was not enough, the other solutions are interesting, but my Software-Developer-Heart says:\ "There is a MODBUS TCP interface, this must be usable". \ From now on, I tried to integrate the system with modbus. \ And it is working :)
