Seems like other people have had this issue recently (https://www.googlenestcommunity.com/t5/Nest-Thermostats/Thermostat-quot-No-Power-e298-quot-Despite-N...). Seems like this is a software/firmware issue if multiple people have suddenly had the same issue at the same time when all their thermostats were working fine previously? However I could not find a resolution - can anyone help?!?!
