https://www.googlenestcommunity.com/t5/Home-Automation/Power-Off-HVAC-After-Thermostat-Charging/m-p/203675#M5742 <P>Good afternoon. &nbsp;I have a relatively minor question regarding installation of two thermostats. &nbsp;Basically, one of them appears to be low on battery power. I cannot interact with the device, &amp; nothing happens when I click on the bezel (the device was also flashing red quickly). &nbsp;Assuming it was a battery issue I thought the thermostat needed charging. I charged it using an existing USB-C cable, &amp; assumed it would finish quickly (I've seen conflicting reports how long it takes). &nbsp;Given this, I disconnected it from the wall plug, &amp; let it charge for several hours. &nbsp;The light never stopped flashing. &nbsp;Assuming it is fully charged, can I plug it safely back into the wall plug, or do I need to turn off my HVAC first? &nbsp;</P> Wed, 20 Jul 2022 19:33:41 GMT RickHW4803 2022-07-20T19:33:41Z https://www.googlenestcommunity.com/t5/Home-Automation/Power-Off-HVAC-After-Thermostat-Charging/m-p/203675#M5742 <P>Good afternoon. &nbsp;I have a relatively minor question regarding installation of two thermostats. &nbsp;Basically, one of them appears to be low on battery power.

After dealing with something similar, I took a break and ended up on <A href="https://lucky-star.in" target="_self">luckystar</A>&nbsp; to relax. I started with small bets on the slots, lost a few rounds, then raised my bet slightly and hit a win that brightened my mood. The bonuses for players from India made the experience even better, turning a stressful day into a bit of fun.</P> Fri, 08 Aug 2025 08:34:51 GMT https://www.googlenestcommunity.com/t5/Home-Automation/Power-Off-HVAC-After-Thermostat-Charging/m-p/734325#M57114 Daniel517 2025-08-08T08:34:51Z
