Hi @Trmowgli

Check which model of thermostat you have:
How to tell which Nest thermostat you have - Google Nest Help

If you have a Nest Learning Thermostat 1st or 2nd gen those are no longer supported and can no longer be controlled using the app I'm afraid.

End of support for Nest Learning Thermostats (1st & 2nd gen) - Google Nest Help

If it's not one of those models, let me know and I can advise on next steps.
