Just tripped over the same thing. Axpert MAX inverter requires .cn cloud connected App. Prev gen had BLE local control. I had a look at trying to reverse engineer the protocol, but not much progress since I refuse to run the App. I can send a UDP message to tell it use my TCP server, but then it seems to require a magic knock at the door.
