Hi BZJ1848,
Thank you for posting in the community. I understand that you want to know if your Nest thermostat will work without Wi-Fi. I'm happy to help you!
Let me tell you that Nest thermostats can work without Wi-Fi, but you will need to control them directly from the device. Additionally, some features will not be available because they require Wi-Fi to function.
If you have any further questions, please don’t hesitate to reply to this post. I'll be happy to assist you further!
Best regards,
Rusell.
