Looking for some assistance to get modbus monitoring working on our Samsung Gen 7 unit. With the aim of putting some sensors in our Home Assistant setup.

I can communicate with the modbus card but find the data and mapping it seem to be a real challenge and the hope of producing a HA sensor showing the realtime COP a pipe dream as I cannot reliably get the LWT RWT and Flow rate. I already have the realtime power from a Shelly Pro em50. But can't get the flow rate. 

I have followed the work Glyn did that fed into eamonhub, but it doesn't seem to work with the Gen 7. https://community.openenergymonitor.org/t/emonhub-support-for-samsung-heatpump-monitoring-via-modbus/21154/

Can anyone assist with this? I am sure if we can get it working it will help others looking to do some HA integration/automation.

Any help appreciated.

Cheers
