Nest Issues Instructions To Cure Glitches After Software Update

The Nest customer support page has a 10-step program for thermostats that won’t turn on after a recent software update. The instructions are a fix for a software update to version 5.1.3 or later that may cause Nest thermostats to become “unresponsive or may not charge the battery efficiently,” the website said. Issues customers may encounter: The thermostat is off in the Nest app and is disconnected from Wi-Fi; the thermostat says the battery is low and needs to shut down; animations are slower than usual; a message says to remove the thermostat from the base and reattach it; the display is dark and unresponsive or has a blinking red or green light; the thermostat can’t control the heating or cooling system.
