Hi,
Paired 3 successfully over the weekend. Hopefully below might help if you want to compare. When I reset them they were powered on:
- Plugged them in fresh out of the packaging. They were powered on, solid white light.
- Used a paper clip to press the reset button. Heard a click and the light started flashing,
then went to a dull glow after holding the rest button in for 12 seconds. - Added Thing in the phone app and gave it a name, pressed save.
- Logged into the IDE and set them all as Zigbee Switch Power
Working very well since.
If they still won’t pair, I would send them back as faulty.
