We do have the hive Thermostat, you can’t put a TRV where the main Hive thermostat is as the main Hive box controls that rad. We have 3 other rads and a towel rad, but they don’t have existing TRV’s so it would mean change the radiator valves. I may well do this next time I get a plumber in. I’m really happy with them, I used to heat the whole house in the morning angled evening. Now it’s just the hall, bathroom, bedroom and kitchen.
