Find your Nest product's MAC address

Each of your Nest products has its own MAC address. The MAC address is a unique combination of letters and numbers a device uses to identify itself on a Wi-Fi network, just like a computer.

Important: Your Wi-Fi router uses MAC address filtering as a security measure to prevent any unknown devices from joining the network. If your router has MAC address filtering enabled, you need to temporarily disable it while you connect your Nest product to Wi-Fi.

  1. Follow the instructions in your router’s manual to disable MAC address filtering.
  2. Continue setup with the app to connect your Nest product.
  3. Once your Nest product is connected to the Wi-Fi, get the MAC address from the Nest app or the Google Home app.
  4. Add your Nest product’s MAC address to the router’s allowed devices so it won’t get blocked from joining the network.
  5. Turn the router’s MAC address filtering back on.

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