Nest thermostats E

This product requires a pin if you want to lock while gone from your home. Unfortunately the pin I had won’t let me in to control my air conditioner. That means if can control through the app the air conditioner will run all night & day. Be careful when this product is tie to your electrical company.

Hi @Confidentqueen,

Thanks for reaching out to the community! I understand that you’re experiencing some inconveniences with your Nest Thermostat E regarding it being locked and requiring a PIN that you don't have, which is preventing you from controlling your AC. Don’t worry! Let me help you out with this.

Please take note that the only way to lock or unlock the thermostat is directly through the app; because of this, the thermostat will not lock itself automatically when you are away from home. Since your thermostat is currently online in the app, we can perform some steps and monitor the device for 24–48 hours to check its behavior.

As the steps vary depending on whether you are using the thermostat itself or the app and since your thermostat is still connected and online please let me share this helpful Help Center article: Lock and unlock your Nest thermostat. Here you will find:

Please try to unlock the device and monitor it for the next 2 days. If the issue persists or if it locks itself again, please let me know, and I will share further steps with you.

Keep me posted!

Best regards,

Debora
