Nest temp reading is wrong

[CBroughtonKW]

We recently suspected the indoor temperature reading is incorrect on our Nest Learning Thermostat (3rd Gen). We have matched it to a mercury indoor thermometer that we now keep near the Nest thermostat. Nest is reading 5° cooler than reading on thermometer. Should I reset to factory settings? Readjust wiring?

Hey CBroughtonKW,

Thanks for posting ― let's sort thiss out.

A few questions:

• When was the thermostat installed?
• Where did you install your thermostat? (in a room and on a wall or stand)
• Do you have other active Nest thermostats? If yes: Do they show the same issue?
• When did the issue start?
• Have you tried any troubleshooting steps? If yes: Would you mind listing them?

Give these steps a try:

1. Go to Settings > Technical Info > Network.
2. Check for the Signal strength value.
3. Restart the thermostat
4. Turn on Sunblock
5. Check if the thermostat is near a heat source

Keep us posted.

Hi everyone,

Just one quick final check in here since activity has slowed down. We'll be locking the thread in the next 24 hours, but if you still need help, I would be happy to keep it open. If there's more we can do, just let me know.

Thanks,
Mel
