Hi Shailjadutt,
Thanks for posting in the community! I understand you're looking for a base plate for your Nest Learning Thermostat (3rd gen) and want to know where you can purchase one. I'm glad to help!
The base plate that the thermostat display unit attaches to is not available for separate purchase from the Google Store. It is included as part of the complete thermostat package because the base and the display are paired during manufacturing. This helps ensure that the thermostat works correctly with your home's heating and cooling system.
Could you tell me if you are experiencing any issues with your current base? If your thermostat is not working properly, it might be due to a problem with the base itself.
I look forward to your response.
Best regards,
Juan
