'Dumb' zigbee radiator valves?

I’ve been trying to find a simple zigbee radiator valve but they all seem to be ‘smart’ and have internal thermostats.

Since I want to create a multizone setup at home with one central control unit for my boiler and phillips hue sensors as my temperature gauges in all my rooms, I want a simple on/off radiator valve but I can’t seem to find any.

I have bought Drayton’s Wiser ones and they seem to have lots of issues not responding to commands if I try to change their modes and target temperatures when I try to emulate a dumb valve.

Any suggestions
