Hi guys, I had a similar problem before, I have a water timer valve, (bluetooth connected to a BT hub aswell), I found that adding a scene (tap to run in my case) on the tuya app will create a scene on home assistant if you have the tuya integration installed. Then you can create a on/off or logic inside the scene of the tuya app. Unfortunately you can’t see then current state of the device, but at least you can controll it. Hope it helps.
