I was able to find a great article that will help you to solve the issue.
Please let me know if you have any further questions.
Thanks for answer my post, I fixed the problem with the help of Google Nest care Team.
After a few times trying different things we remove my Thermostate from my add and try the process again.
- Reseting the Nest Connect
- Disconnect others devices from my phone bluetooth
- Make sure your phone is connect to Wifi 2.5Ghz
- Start setup
This make me add the nest. Probably your look will present issue to connect if this happen remove the batteries, take the two screw and press the little blue button on the back but before put 3 batteries back then press and at the same time add the other battery this will help you to reset the lock. Them follow the instructions this helped me to finally added the lock on my account.
