I am still unclear how practically to do this. The OAT has been falling overnight, and is currently 4 degrees, ie approaching the defrost cycle range....
Yes, it is in one of the modbus registers, and I just collect it as I would collect any other register value. I'm guessing it is set by an algorithm t...
