Hello Carlosavinon,
Thank you for taking an interest in our community. I’m sorry to know that you’re having trouble with the QR code and entry key of your Nest Thermostat E to set up. No worries. It’s a pleasure to help.
To set up your Nest device, you'll typically need to scan a QR code using your phone's camera. If you encounter difficulties, try scanning in a brighter spot. Check out some helpful tips in this article: Troubleshoot QR code scanning with your phone’s camera.
Also, you can set up manually entering the entry key into the Nest app.
- Turn the ring to Settings and press to select.
- Choose the Nest app and get the entry key.
- Your thermostat should show you a 7-character key to enter in the Nest app.
- Another way to find it is behind the thermostat’s display.
For your reference and further information, visit this article: Can't connect Nest thermostat to the app.
Let me know how it goes,
Best regards,
Daniel.
