Each of your Nest products has its own MAC address: a unique combination of letters and numbers a device uses to identify itself on a Wi-Fi network, just like a computer. MAC address filtering is used as a security measure to prevent any unknown devices from joining the network.
- If your Wi-Fi router has MAC address filtering enabled, you can temporarily disable it while you connect your Nest product. Follow the MAC address filtering instructions in your routerâs manual.
- Continue setup with the app to connect your Nest product.
- Once your Nest product is connected to Wi-Fi, look up the MAC address in the app by following the instructions below.
- Add your Nest productâs MAC address to the routerâs whitelist so it wonât get blocked from joining the network.
- Turn the routerâs MAC address filtering back on.

Your Nest product must be connected to Wi-Fi for the MAC address to be listed in the app.

Get the MAC address for older cameras or thermostats
Some older Nest products have their MAC address on the device itself. If yours does not, use the app instructions above.
Cameras
