Pairing Tuya Radiator Valves

[Rowan Sylvester-Bradley]

A year or more ago I bought 20 Tuya remote controllable radiator valves at the cost of several hundred pounds with the intention of controlling all the radiators in my home (I have 19 radators) via OpenHAB or Home Assistant. I also bought two Tuya Zigbee gateways. I have not been able to use any of these devices yet, because I can't find out how to pair the valves with the gateway so that I can control the valves remotely. I have asked everyone that I can think of how to do this, but either I have not had replies, or the replies have not been effective (e.g. the valves do not behave as the correspondent has described). Maybe the firmware in my devices is newer or older than what other people have got, or something. Someone surely must know how these devices work? If you know how to do this, or how to find out, please let me know.

Thank you - Rowan
