Just installed the Modbus connector today, and installed the Modbus integration into Home Assistant, and loving the extra functionality and data over the Modbus Cloud version, however, having an issue with an entity, specifically the PV Power .. which I had used on the Cloud version, and it showed the total solar being produced now

As per the image below, I can see PV1 and PV2 ... but PV Power is showing as Unknown .. any ideas?

Wait until the sun is up tomorrow (i.e. you have pv power) and then restart your HA, that sensor is a riemann sum and it freezes occasionally on new installs.
