Cannot connect Iphone app to Nest Protect

Community Member

My iPhone app is no longer connected to Nest Protect.  I had it set up, but I've noticed it has  quit working.  I cannot get it to reconnect.

How do I reconnect without removing the 7 alarms from their ceiling installs?

Thanks, Mark

Unfortunately you’ll need the QR code or setup key. The QR code and setup key are physically printed on the back of the device. Once you have either the QR code or setup key:

  1. Open the Nest app.
  2. Tap the Settings cog > Add product +.
  3. Follow the steps on screen.

I'd definitely recommend writing down the setup key for each Protect and keep it in a safe place.
