Hi @Pae!
Thanks for posting in the community.
I’m sorry to hear that your Nest thermostat stopped working on your phone. No worries, I’m glad to help you in this.
To further assist you, I will need some information. Here are some questions for you:
- What is the exact model of your Nest thermostat?
- What’s the software version of your Nest thermostat?
- Do you control the Nest thermostat from the Nest app or the Google Home app?
- How far is the Nest thermostat from the Wi-Fi router?
- Do you see any message on the app or the Nest thermostat display?
In the meantime, you can check the next article: Nest thermostat is offline.
I will be waiting for your response.
Regards,
Daniel.
