What does the green blinking light mean on my nest thermostat?

A green blinking light on your Nest thermostat typically indicates that it's in the process of connecting to your Wi-Fi network or is attempting to update its software. If the light continues to blink for an extended period, it might suggest that there is an issue with the Wi-Fi connection, and you may need to check your network settings or restart your router. If the problem persists, consider resetting the thermostat or consulting the Nest support resources for troubleshooting.
