Reverse engineering Honeywell HR92 TRV

Has anyone ever attempted reverse-engineering the radio protocol driving these valves? It should be an FSK 868Mhz. I own this system, the valves are fine, but the control system is really lousy, and I can only get current temperatures from their cloud server...
