Installing a Google Nest Doorbell takes about 30 minutes for the battery model and a bit longer for the wired one. The Google Home app walks you through setup and shows a video of each step. Wired models need doorbell wiring with enough power: Google specifies a transformer rated 16 to 24 V AC and 10 to 40 VA for the wired 2nd and 3rd gen doorbells. If you are not comfortable with wiring, hire an electrician.
Quick Answer
Open the Google Home app, tap Add, Google Nest device, and scan the QR code on the doorbell. Mount the plate, connect the wires if you have a wired model, clip the doorbell on, and finish setup in the app.
How to Install a Google Nest Doorbell
- Charge the battery model fully before you start.
- Open the Google Home app, tap Add, then Google Nest device, and scan the QR code on the back of the doorbell.
- Wired model: turn off power to the doorbell at the breaker, remove the old doorbell and note the two wires.
- Attach the mounting plate (use the wedge if you need a better viewing angle) and connect the two wires to the terminals. Battery models can skip wiring.
- Clip the doorbell onto the plate until it clicks, restore power, and follow the app to connect it to Wi-Fi.
- Press the button to test the chime and live view.
Battery vs Wired
| Item | Battery / Wired |
|---|---|
| Power | Rechargeable battery / Doorbell wiring |
| Transformer needed | Optional for charging / 16-24 V AC, 10-40 VA |

| Charging | Remove and charge over USB-C / Not needed |
| Install time | About 30 minutes / About an hour |
Troubleshooting
- Yellow blinking light on a wired model: the transformer may be too weak. Google recommends an electrician upgrade it.
- Cannot scan the QR code: type the setup code printed below it instead.
- Weak Wi-Fi at the door: move the router closer or add a mesh point.
- After setup, see how to add a Nest Doorbell to Google Home and how to charge the battery model.
