Hello wjaceh,
I just bough an A1M modbus interface for my Mitsubishi Ecodan Air-to-Water heat pump as I was aiming at same objective as you (optimize power in function of electricity price - actually for me it’s about PV self-consumption optimization). Have you finally found a way to do so?
Before I had also the Melcloud solution with the Wifi interface, I was hoping that the Modbus would have given me better options but after the first attempts I am realizing that I might have just wasted some money…
Regards
Guido
can you use A1M modbus interface finally?
