Hello @HApple
Thanks for reaching out to our Nest community about the Airwave option. I apologize for all the inconvenience. Don't worry, I'm here to help you with it.
I suggest trying to perform a Reset On Your Nest thermostat and then checking if all of your system is on and correctly wired.
Feel free to keep us posted if this error is still there. I will definitely do my best to find a solution for you.
Best regards,
Douglas.
