Upgrading your smart thermostat probably wasn’t too high up on your list of priorities until Google revealed that it would end support for its first and second generation Nest Learning Thermostats in October.
Once October rolls around, those older Nest thermostats will lose all smart functionality. This means you won’t be able to control them remotely using your smartphone or with your voice through your smart speaker. These older models will continue to work but only as a regular thermostat where you’ll need to adjust them manually.
