Hey there,
 
I would be more than happy to assist you and answer this for you. The voltage for your battery will fluctuate, but it should be higher than 3.6V when it’s charging normally.
If your thermostat isn’t receiving enough power to charge the battery, and it falls below 3.6V, your thermostat will turn off Wi-Fi, delay software updates, and disable the screen to preserve the battery charge and delay shutting down completely.
  • 3.7V is required to install a software update.
  • 3.6V is required for the display to turn on when you approach.

Hello,

I installed my nest thermostat yesterday and it updated without any issues, I shut off the display turn on during approach because it just was not necessary.  This morning it showed that the Nest was offline for 6 hours overnight but then just after 830 this morning it showed online, working and with a voltage of 2.87 with OK as the battery status. It has been on 8.5 hours today with no interruptions... Is this normal? I did not charge the device prior to install so I am curious if it the voltage was truly 2.87, how did it perform the update and also, for about 15 seconds after placing the nest on the base it had an N260 error that flashed for maybe 5 seconds, disappeared and did not flash or show again. What is going on with this device? Your assistance is appreciated.

Hi Russellv,

 

Thanks for reaching out. I'm sorry to hear that you're having an issue with your Nest Thermostat. I'd love to know more about this and I have a few questions:

 

  • What type of Nest Thermostat do you have?
  • How is your Nest Thermostat wired?
  • What is the power reading of your Nest Thermostat? You can find this by going to Settings > Technical Info > Power.

Looking forward to your response.

 

Thanks,

Edward
