Nest Learning Thermostat Technical Info Tour

You can find all the technical details about your Nest Thermostat in Technical Info option in Settings.

If you need to find any technical information regarding your Nest Learning Thermostat, such your IP address or what software version you have, you can find it in Technical Info. Press the ring to access the menu and turn the ring to SETTINGS. Within Settings, select TECHNICAL INFO.

You’ll find information regarding your Nest Thermostat's sensors, your Wi-Fi Network, the serial and model numbers associated with your device and much more. Below is a list of all the information available to you in Technical Info.



The name you’ve assigned to your Nest Thermostat.

If you want to change the name, you’ll have to go back to SETTINGS, then to NAME, and change the name there. There are a few generic names you can use such as Nest, Hallway, Office, or you can type your own.


Current temp

The current temperature of your home or office, displayed on the Nest Thermostat's temperature screen. Determined by multiple sensors within the Nest Thermostat.

Target temp

The target temperature that the Nest Thermostat is working to reach.

Rel. humidity

The relative humidity in your home or business. Determined by one of the sensors inside the Nest Thermostat.


These sensors provide information on near-field activity, far field activity, and ambient light.


Equipment sensed on

This confirms the wires you’ve connected to the Nest Thermostat base. This information can also be found (along with a diagram of the wiring) in SETTINGS > WIRING.



The current voltage of your battery. A voltage of at least 3.7 is required to install a software update. A voltage of 3.6 is required for the display to turn on when you approach. The Nest Thermostat's battery voltage will fluctuate, but your voltage should generally be higher than 3.6V if everything is functioning normally. The VOC, VIN, and LIN values refer to the voltage and electrical current conditions under which the Nest Thermostat's battery is charged.



This provides information about your Wi-Fi connection. If you’re not connected to a network, you will see “Client not connected.”

If you are connected, you’ll see your network name, the network round-trip time for a simple network ping (measured in milliseconds), and your signal strength, measured out of 100. A value of 75 is considered strong, while a value of 36 or lower is considered weak.


This tells you what type of security is on your Wi-Fi network.

Currently, the Nest Thermostat can connect to open (no-password) home networks or to networks that follow PSK (Pre-shared key mode) or personal security protocol, specially designed for the home and small business. These security systems are typically labeled WEP, WPA, and WPA2 Personal.


This tells you the Nest Thermostat's Wi-Fi network interface, however, it’s unlikely you’ll ever need this information or see it change.

IP address

This provides the IP address for your Nest Thermostat on your wireless network.

Subnet mask

This is also specific to your Wi-Fi network connection. A subnet mask is used to identify the network address of an IP address.


This is the IP address of the router that your Nest Thermostat is connected to.

Name servers

This is the name server associated with your Wi-Fi network. These are typically provided automatically to your router by your Internet service provider. A name server translates domain names into IP addresses.

Search domains

This is used if your Nest Thermostat needs to resolve an unqualified domain name.

Nest server URL

This indicates where the Nest Thermostat uploads data:

Last upload

The exact date and time of your last upload. Uploads are done automatically, so this information is there to tell you when your Nest Thermostat last had information uploaded.

Last update

The exact date and time of your last update; as with the last upload, this is done automatically and simply tells you when your Nest Thermostat was last updated with new software.

MAC address

This is the unique identifier assigned to your Nest Learning Thermostat.



Auto-Schedule displays the last time the learning schedule was updated and the current phase of learning. The Nest Learning Thermostat compiles the learning adjustments each day and processes them at the end of the day, which is displayed here.  


Software version

The version of software the Nest Thermostat is currently running.


The model of your Nest Learning Thermostat display.

Serial number

Your Nest Thermostat's unique serial number.


Software version

The version of software the Nest Thermostat base is currently running.


The model of your Nest Learning Thermostat base.

Serial number

The serial number of the Nest Thermostat base.
