Nest 3rd Gen constantly having issues with sensors

[lordneeko]

 This is a regularly recurring problem where the set temp is below the sensor temp but it still doesn't come on. The fix? Switch to the other sensor, then back. When I first got the sensor it was very reliable and followed my set schedule...and then I could override the current set sensor. Now, it is a huge pain in the rear. Manually switching sensors doesn't stick for more than like 5 minutes, and many times the nest won't control the temp based on even the scheduled sensor. I have NO desire to buy a new nest, when the software for the current one has gotten worse and worse over the 10 years I've owned it.

Hi, @lordneeko,

Thank you for reaching out to the community. I'm truly sorry that the communication between your Nest Sensor and Nest thermostat isn't controlling the temperature correctly. I'm happy to help you find a solution.

Often, this issue occurs due to a low thermostat battery, which impacts sensor connectivity. If the sensor battery is low or falls below 5%, the sensor can't transmit temperature data to the thermostat. To assist you, please follow these steps:

Replace the Nest sensor battery: The Nest Temperature Sensor uses a CR2 lithium battery commonly available at local stores.

• Insert a coin into the slot on the sensor's back.
• Unscrew the battery cover by turning the coin.
• Replace the battery.
• Replace the cover.

Check the battery level on your Nest thermostat:

• Settings > Technical Info > Power > Battery
• If the battery level is lower than 3.65 volts, charge the thermostat for at least 2 hours, then try to connect it with the sensor.

If you encounter any trouble connecting the sensor and the thermostat, please follow these troubleshooting steps:

• Restart the thermostat.
• Remove the sensor battery for at least 30 seconds, then put it back.
• Try to connect the Nest Sensor with the thermostat.

Please let me know how it goes.

Best regards,

Ana

Thanks for the AI generated response.  This is not a battery issue (it's almost brand new), the Nest registers the temperature just fine.  This is a software issue in the NEST controller (or app, or wherever that is stored) that doesn't stick when I manually select a sensor during a time period. It just changes back a few minutes later, instead of "selecting the sensor until the next scheduled change" (which is the message of the popup when you manually select a sensor). This sensor logic has been a bit janky for the last year or so, and recently got worse.

Hi, @lordneeko,

Thank you for your quick response and for clarifying the information. I apologize if the previous steps didn't help. I'm happy to assist you further.

Let's perform a connection test following these steps:

• In the Nest app, go to Settings > Nest Temperature Sensors > Affected Sensor > Check Connection.
• Move the Nest Temperature Sensor close to the thermostat, anywhere from 1 to 3 feet.

Please let me know if you receive any error messages. 

Additionally, please ensure that the Nest thermostat software is updated. 

Keep me posted.

Best regards, 

Ana

Connection to sensor is good.

Hello @lordneeko,

Thanks for posting in the community. 
I appreciate your effort, it seems that everything is good but let's follow some steps to troubleshoot the issue you are having.

Let's try the following steps:

1. Restart the thermostat.
2. Remove the sensor battery for at least 30 seconds, then put it back.
3. Check if you are logged in to the correct account and can find the sensor in the Nest app or Home app for Nest Learning Thermostat (4th gen).

• If not, they need to change accounts or unpair and pair the sensor to the correct home structure. If the customer wants to use a new or different account, the sensor continues to show in the old account until removed from that account.

4. To reset the network settings of the thermostat, go to Settings > and then Reset > and then Network. If the network isn't available, select Account connection instead.
5. Reconnect the thermostat to the network. If you reset the thermostat's Account connection, also reconnect the thermostat to the account.
6. Run a connection test.
7. To perform a full reset, remove the battery from the sensor for 5 minutes and then put it back.
8. Unpair and pair the sensor back to the account.

Once the sensor is removed, please monitor it for 24 to 48 hours, and then you need to add the sensor back, you can check the following link for further information: How to set up and install the Nest Temperature Sensor in the Google Home app.

Please let me know how it goes. Thank you.

Thank you all for providing support, but this is NOT a tech support problem. It is a software problem that has been problematic for the NEST sensors for years, worse the last 6 months or so. It's a bug in the software... unfortunately I don't think anyone at Google actually maintains the software anymore anyways.
