That’s a nice gadget!
It’s true it has to be supported by the Tuya zigbee app.
With Tuya (related) devices the firmware can be different for the same type, or similar looking device.
The needed info can only be discovered by buying it, pair and interviewing it, and then request support → here’s the how-to.
Or, the quickest, but not the most easy way (and, it depends on the cloud):
- buy a cheap (~ E19,-) Tuya zigbee hub
- control Homey via raw commands (Tuya MQTT-ish version) with the Tuya Cloud app.
Oh when you’re interested, I found a much cheaper one here, around E 14,60
