Before you purchase or install Google Nest Hello, you need to make sure your current doorbell and chime wiring can deliver enough power. If they don’t, you can have a Nest Pro upgrade your system and install it for you. Installing Hello yourself involves some basic wiring on your chime and doorbell, and drilling new holes to mount Hello.
The Nest app will walk you through Nest Hello installation step-by step with detailed instructions, so you should use the app as your primary guide, but we’ve provided the basic steps and some extra details here.
You can also watch a video about installing Nest Hello, if you want to see an overview of the steps.
1. Check compatibility
While most wired doorbells can be replaced by Nest Hello, there are some cases where there isn’t enough power or too much power. So it’s essential to check that your current doorbell can be replaced by Nest Hello. Please go to the following article for detailed instructions:
Note: If the compatibility checker says you’re not compatible, you can have a local Nest Pro replace your transformer at the switchboard (DIN rail transformer) and install Hello for you.

6. Take a picture of the chime's wires
7. Tell the app about your chime's wires
8. Follow the app's chime wiring instructions
Next, the app will walk you through the steps to connect your chime wires.
You’ll get custom instructions depending on what wires you entered into the app. So it’s critical to follow the specific wiring the app tells you.
We’ll run through the most common wiring example for replacing a front doorbell with Nest Hello. If your doorbell wiring is different, don’t worry, the app has detailed instructions for advanced wiring as well. So follow what the Nest app tells you to get the right wiring instructions for your chime.
Disconnect the wire from the front terminal on the chime.
When you're done, the wiring should appear as pictured.
9. Mount the chime connector
Once the wiring is done, find a place to put the chime connector.
Make sure the connector and wires don’t touch the chime or any moving parts, or it may not sound right or work at all.
If space is very tight, it may be easier to attach the connector to the outside of your chime cover.
10. Replace your chime cover
11. Disconnect your current doorbell
Remove your current doorbell and disconnect the wires. You’ll probably need a screwdriver for this step.

Nest Hello will take a few seconds to turn on. You’ll hear a chime and the light ring should start pulsing blue.
If it’s not, select “No, it’s not blue” in the app and it will help you troubleshoot.
19. Troubleshoot if needed
If there’s no light on Nest Hello, go back to your chime box and double check that you’ve correctly wired the Nest connector.
If the light is blinking yellow, Nest Hello isn’t getting enough power to stream video. You’ll need to contact a Nest Pro to upgrade the voltage of your doorbell wires.
3. Connect Hello to the Nest app
1. Enter Hello's location and your Wi-Fi info
First, you’ll tell the app where you installed Nest Hello.
Then you’ll select your Wi-Fi network and enter the password.
If you already have a Nest product installed in your home, Nest Hello will try to get your Wi-Fi info from it.
If Hello can’t connect to your Wi-Fi network, you can try moving your router a bit closer or adding a Wi-Fi extender.
2. Test the video stream and chime
Once Hello is connected to Wi-Fi and the app, the app will test the video.
Ring the doorbell to check that your chime is working. You should also get a notification from the app that someone’s at your door.
If you have an electric chime that doesn’t have moving parts, you may need to adjust the duration with the app so you can hear it ring.
3. Troubleshoot if needed
- If you have a mechanical chime with moving parts and it didn’t ring or didn’t sound right, remove the chime cover and check that the wires aren’t touching any moving parts.
- Then test your chime again.
- If your chime still doesn’t sound right, try installing the connector on the outside of your chime cover.
4. Select other options
For the last step you’ll choose some more settings:
- Opt to try out Nest Aware for free
- Pick a language Hello will speak to visitors
- Choose to turn on audio recording and familiar face detection
