Hello Sriz,

Thanks for posting and for keeping us in the loop on what you've done to have your concern rectified.

I'm glad to hear that you were able to resolve the E299 message code on your Nest Thermostat by changing the battery. In the meantime, please observe your thermostat's behavior, and if you ever encounter similar problems in the future, let us know.

Best regards,
