How to install Nest Hello with the Indoor Power Adapter

1. Things to know before you begin

Nest Hello is designed to replace a wired doorbell
and use your current doorbell chime. But you can
use the Indoor Power Adapter to install Hello if you
don’t currently have a doorbell, if you have a
wireless battery-powered doorbell, or your doorbell
system won’t work with Hello for other reasons.

The steps are different to install Hello with the
Indoor Power Adapter, so follow this guide closely.
You’ll need to skip some steps in the app and follow
them here instead.

You can also watch a video to learn the basic steps for installing Hello with the power adapter. 

  • Purchase Nest Hello and the Indoor Power Adapter
    from the Google Store.

  • If you would like a separate doorbell chime in addition
    to using the Nest app on your phone, you can purchase
    a Google Nest Hub or other Google Assistant-enabled
    device from the Google Store or a local retailer.

  • You’ll need to drill a hole completely through your
    home’s exterior wall to run the power cable to
    a wall outlet inside your home. Contact a local pro if you don’t feel comfortable drilling all the way through the wall. 

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

    is off If you need to, you can also turn off the main
    power switch at the breaker box.

6. Drill and install the wall plate

  • If you are replacing your current doorbell

You may be able to mount Hello over the old doorbell button’s location. But 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 Hello about 4 feet, or 1.2 meters high- this is 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 Hello’s wall plate hole (as pictured).
If they don’t, they can prevent Hello from locking onto the wall plate.

2. Drill a hole for the power cable all the way through the wall.
Use a 11/32 inch (9 mm) drill bit that’s long enough to go
completely through the wall. Remember that you’ll need to
know where any in-wall plumbing and electric wiring are before drilling.

3. Drill pilot holes for the screws with a 3/32 inch (2 mm) drill bit.
Use the included masonry bit and wall anchors if you’re drilling into stone, stucco, or other hard materials.

4. Mount the wall plate with the screws.
Important: Make sure the wall plate is right side up. The horizontal screw hole should be at the bottom.

7. Run the power cable through the wall

Go inside your home and slip the wall grommet over the adapter cable. Then 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.

8.  Connect the adapter wires to Hello

Connect the wires to Nest Hello.

  • 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 Hello properly connect to the wall plate.

9. Mount Hello

Slide the top of Hello into the wall plate. Then press
until the doorbell clicks into place.

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

Tip: If you ever need to remove Nest Hello, push the
included release tool (or a thumbtack) into the hole
on the bottom to release it.

10. Switch the power on and plug in the adapter

Skip ahead in the app until it asks you to switch the power back on. Then turn the power on at your breaker or fuse box and plug the power adapter into the indoor wall outlet.

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.

11. Check Hello's power

Once it’s plugged in Nest Hello will turn on, and its light ring will turn blue.  


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

12. Finish setup with the app

1. Connect to Wi-Fi

First, you’ll tell the app where you installed Nest Hello. Then select your Wi-Fi network and enter the password. Hello will then connect to Wi-Fi.


  • If Hello can’t connect to your Wi-Fi network, you can try to move your router a bit closer or adding a Wi-Fi extender.

  • If you already have a Nest product installed in your home, Hello will try to get your Wi-Fi info from it. Try to move it closer to Hello if possible or, temporarily uninstall Hello and plug it in closer to the assisting product while you try to connect to Wi-Fi again.

2. Test the video stream

Once Hello is connected to Wi-Fi and the app, the app will test the video.

3. Turn off the chime and test

  2. Tap your Hello on the Nest app home screen. Then tap Settings Nest settings icon.
  3. Set the Indoor chime On/Off option to off.
  4. Now press Hello’s button to check that it’s working. You should also get a notification from the app that someone’s at your door.
