It’s not possible and even not necessary to add the „LSC Smart Dimmer Switch“ to the TUYA-App. The Dimmer Switch works only as a remote for your bulbs/switches, in this case you can only turn on/off or dimm (brighter/darker) the bulb which it is connected to. You can’t control the functions of the „LSC Smart Dimmer Switch“ with your smartphone, because it is a remote like your smartphone with TUYA-App.
Just pair the „LSC Smart Dimmer Switch“ with any bulb/switch (only one item possible!) and it works like a charm.
To do so:
- Add the bulb/switch as an item to your TUYA-App, connect it to your WiFi, turn the bulb/switch on
- Turn on the „LSC Smart Dimmer Switch“ by hand (on/off on the side), wait a moment
- Turn the bulb/switch off and then on by hand
- Now press the dial on the „LSC Smart Dimmer Switch“ for 5 seconds, until the small LED is blinking blue
- now the „LSC Smart Dimmer Switch“ connects (pairing) automatically to the bulb/switch, the chosen bulb/switch begins blinking if connected
- Ready…now you can control your bulb/switch with the „LSC Smart Dimmer Switch“! That’s it!
Hope this helps…
