Learn how your Nest products connect to each other and the internet

Nest products are designed to work together, so they can communicate with you and each other in a variety of ways. They use Bluetooth, NFC, Wi-Fi, and Thread which is a low-power wireless mesh network for device-to-device communications.

Nest products don’t connect to each other through your Wi-Fi router. In most cases, they use Wi-Fi to send their status to the Nest service which then sends that information to other products in your home and the app. In other cases, they use Thread wireless networking to directly connect to each other.

Learn about Thread networks

Thread is a type of mesh network. In a mesh network, all devices can act as a router, letting them relay information directly to each other without the need for a central router. This has several advantages:

  • Improved range

    Thread can also reach the far corners of large homes because each device is a network router. Since every device relays information, the more devices on the Thread network, the further the wireless signal can reach. This is especially helpful in larger homes or homes where the construction restricts the wireless signal range.

  • Low power

    No one likes to replace batteries, but batteries free you from having to plug into a wall socket or hard wire a device. Thread also requires very little power, so even battery powered devices like Google Nest Protects and Google Nest Detects can connect to the internet and other Nest products while staying charged for years.

  • Independent from Wi-Fi

    Thread doesn’t depend on your Wi-Fi router or network. So if your router loses power or its internet connection, Nest products can still communicate with each other and with you.

    For instance, all Nest Protects in your home can still tell you what room the smoke is in and sound the alarm. In addition, if you have Google Nest Secure, Detects will still be able to tell Google Nest Guard if there’s motion or a door or window is opened, let you know with a spoken alert and sound the alarm if needed.

Although Thread networks have some key benefits over common Wi-Fi networks, keep in mind that they’re also subject to wireless interference that can affect range and performance.

How Nest products use Thread and Wi-Fi

Nest products use Wi-Fi and Thread for various things like downloading software updates, sending app notifications, and devices communicating with each other. Some products only have Wi-Fi, some have only Thread, others have both.

For example, the Google Nest x Yale Lock only has Thread. So it connects to internet through another product which has both Wi-Fi and Thread, like Nest Guard or Google Nest Connect.

How Nest products use Bluetooth and NFC

Google Nest cameras, video doorbells and 2nd gen Nest Protects use Bluetooth Low Energy (or BLE) to connect to your phone or tablet during setup. 2nd gen Protects also use BLE for App Silence and to start a Safety Checkup test.

Note: For Google Nest Thermostat E with Heat Link customers in Europe, your phone or tablet must support BLE. This is only a requirement for Nest Thermostat E models sold in Europe. it's not a requirement for Nest Thermostat E models sold elsewhere, or for other models of Nest thermostats such as the 3rd gen Nest Learning Thermostat.

How to turn on Bluetooth on your phone or tablet

Turning on your phone or tablet's Bluetooth varies depending on the model and which OS your phone uses.

  • On Android devices, the app will automatically turn on Bluetooth when needed. Bluetooth settings are usually found in your Quick Settings or the Settings app.

  • On iOS devices, the app can notify you that Bluetooth is needed, but you'll need to manually switch it on. Bluetooth settings are usually found in the Control Center.


Google Nest Tag uses NFC when you hold it on Nest Guard to arm and disarm the alarm.
