Hi unfortunately after a LOT of back and forth with Worcester it is the case that this model isn't compatible with 3rd party controls (Nest/Hive). Unfortunately the only smart meter alternative is their own brand but the reviews of the app are awful so I've stuck with the Comfort + 2 RFI...
I have a Worcester GC2000iW C Combi boiler - it appears to be the model (circa 2019) that is only compatible with Worcester's own Comfort +II RF controller and the EasyControl Key. The Control Unit is pre-installed with the Key.
I wanted to know if anyone has had any success circumventing it...
