Hi all

Just set up opentherm on a gen 4 hive mini. The hive hub and receiver both call for heat (green light on the receiver and the app thinks it’s used energy) but the boiler does nothing. Uploaded a pic of the boiler for details too.

I have had to switch to the standard on/off system as I just cannot get opentherm to work. Any suggestions on what we’re doing wrong with opentherm?
