I didn’t see this anywhere else on the forum, so for anyone else having problems pairing this switch, this is how I did it.
- Hold down the bottom (off) switch until the light flashes red, then let it go. Takes about 10 seconds.
- Click “Add Device” in the smartthings “Things” menu.
- While the red light is flashing, hold down the bottom (off) switch again for about 5 seconds.
At this point the light should flash green a few times and the device should show up as detected in Smart things.
The directions included elsewhere on the Smartthings site said to hold down the bottom button for 5 seconds - this was completely wrong.
