So far, I have just found an austrian brand were I could integrate it using Modbus-TCP by sending to the system two values (current production kW, current excedent production kW).
The brand for the Aerothermia is IDM, I think
Do you know any other brands to include in my list to make the final decision?
Thanks in advance.
P.S: My current Solar system is using both MQTT and Modbus protocol to integrate between systems (car chargers, reles, temp sensors…)
