We have the modbus interface installed in the outdoor integrated unit. It is connected onto our network using a Waveshare RS485 to ETH (B) POE device. We use these for all monitoring and metering. Inverters, batteries, remote CT etc.
All we can get out of it is LWT RWT and by accident FR. These are being read from using modbus sensors in HA directly.

They do seem to work but we can’t seem to be able to get other info like Target Water Law temp, Indoor temp, Outside temp, Active Electrical power consumption, Compressor % and Pump % etc.
Any help appreciated.
Cheers
