Hi @Liljohn42!
Thanks for posting in the community.
I’m sorry for the inconveniences that you’ve been experiencing with your Nest thermostat. I can see that it won’t let you connect your thermostat to the WiFi. You are receiving a message with an M code. Let me help you with this.
To better assist you, I need some extra information. Here are some questions for you:
- What type of HVAC system do you have?
- What Nest thermostat model do you have?
- What troubleshooting steps have you done so far?
- When did the issue start?
- Is the Nest thermostat already set up in your account?
- What is the exact M code that you are receiving?
In the meantime, you can check the next article for further information: Troubleshoot Nest thermostat help codes.
Tell me how it goes.
Regards,
Daniel.
