Install Nest doorbell with an indoor power adapter

The Nest Doorbell (wired) is designed to replace a wired doorbell and use your home’s current doorbell chime.

The Nest Doorbell (battery) can either replace a wired doorbell and use your home’s doorbell chime, or use its internal rechargeable batteries to stay powered.

If your home doesn’t have a doorbell, or if your current doorbell system is incompatible with Nest doorbells, you can use an indoor power adapter to install a Nest doorbell instead.

Important: The indoor power adapter is sold separately from the Nest doorbell. If it's available in your country, you can purchase the indoor power adapter from the Google Store.

Safety tips

You need to drill a hole completely through your home’s exterior wall to run the power cable to a power outlet inside your home. Before you do, consider the following:

  • You need to know where any in-wall plumbing and electric wiring are.
  • Check the building codes where you live to make sure your installation is safe.
  • You can contact a local professional if you don’t feel comfortable drilling all the way through the wall.

Warning: Do not plug the adapter into an outdoor power outlet. It isn’t weatherproof.

5. Drill and install the wall plate

 If you need to replace your current doorbell, you might be able to mount your Nest doorbell over the old doorbell button’s location. However, you might need to drill a new hole or remove the current doorbell wires and drill out the existing hole so the power adapter’s cable can pass through the wall.

If you don’t have a doorbell, install your doorbell about 4 ft (1.2 m) high, where most doorbells are located.

  1. Use the wall plate to mark holes to drill for the cable and the screws. Use a bubble level to check that the wall plate is straight.
  • Important: The doorbell wires must come through the bottom of the wall plate hole (as pictured). If they don’t, they can prevent the doorbell from locking onto the wall plate.
  1. With an 11/32 in (9 mm) drill bit, drill a hole for the power cable completely through the wall.
  • Note: You need to know where any in-wall plumbing and electric wiring are before you drill.
  1. Drill pilot holes for the screws with a 3/32 in (2 mm) drill bit. Use the included masonry bit and wall anchors if you need to drill into stone, stucco or other hard materials.

  2. Mount the wall plate with the screws.

  • Important: Make sure the wall plate is right side up. The Nest logo should be at the bottom.

6. Run the power cable through the wall

  1. Go inside your home and slip the wall grommet over the adapter cable.
  2. Run the cable through the hole to the outside.

Important: Don’t plug in the adapter yet. You might damage it if the wire ends touch each other. Keep it unplugged until you finish installation.

7. Connect the adapter wires to your doorbell

It doesn’t matter which terminal you connect a wire to.

Make sure the screws are snug and that the wires point down as shown. This is so excess wire can be tucked back into the wall, letting the doorbell properly connect to the wall plate.

8. Mount your doorbell

  1. Slide the top of the doorbell into the wall plate.
  2. Press until the doorbell clicks into place.

If it doesn’t seat properly or you doesn’t click, check that you’ve fully tucked any excess wire back into the hole.

Tip: If you ever need to remove your Nest doorbell, push the included release tool into the hole on the bottom to unlock it. You can also use a thumb tack or paper clip.

9. Switch the power on and plug in the adapter

  1. Skip ahead in the app until it asks you to switch the power back on.
  2. Turn the power on at your breaker or fuse box.
  3. Plug the power adapter into the indoor wall outlet.
  • Note: You can use an extension cord to reach, if needed. If you have excess cable, you can either tuck it back into the hole in the wall or use a cable tie to wrap it up.

10. Check your doorbell's power

Once it’s plugged in, your Nest doorbell should turn on, and its light ring should turn blue.

Troubleshooting

If the light ring doesn’t turn on, double check that the adapter is plugged into a live power outlet. Then, unplug the adapter and plug it back in. Also, make sure the wires are properly connected to the back of the doorbell lo and that the screws are snug.

11. Finish setup with the app

 1. Connect to Wi-Fi

Tell the app where you installed your doorbell. Then, select your Wi-Fi network and enter the password.

Troubleshoot issues

  • If your doorbell can’t connect to your Wi-Fi network, you can try to move your router a bit closer or add a Wi-Fi extender.
  • If you already have a Nest product installed in your home, your doorbell should try to get your Wi-Fi info from it. Try to move it closer to your doorbell if possible or, temporarily uninstall your doorbell and plug it in closer to the assisting product while you try to connect to Wi-Fi again.

2. Test the video stream

Once your doorbell is connected to Wi-Fi and the app, the app should test the video.

3. Turn the chime off and test

Before you test your doorbell, turn off the chime option in the app, even if you don’t have a wired doorbell chime installed.

  1. To exit the set up, tap Done.
  2. Tap your doorbell on the app home screen. Then, tap Settings Nest settings icon.
  3. Switch “Indoor chime” off.
  4. Press your doorbell’s button to check that it’s working. You should also get a notification from the app that someone’s at your door.
