Radiator valve drivers

Hi.

I'm hoping to connect my radiators to Hubitat.

However, I've only found one radiator valve driver, the officially supported one from Fibaro which is Z-Wave and quite expensive.

So I'm wondering if anybody can point me to some community drivers for other radiator valves that I could try out. Preferably Zigbee.

Something like this for example:
