Step-by-Step Installation Instructions
The following section outlines the key steps for installing the Google Nest Hello doorbell, based on verified installation procedures and user experiences.
1. Preparing the Electrical System
Before beginning the physical installation, it is essential to ensure that the electrical system is ready. This includes identifying and turning off the correct circuit breaker. In most cases, the doorbell transformer is located near the HVAC system, typically in the garage or basement. If the exact location is unclear, it is safe to test each breaker until the doorbell stops functioning.
For users who cannot locate the circuit breaker, an alternative method involves opening the chime box and disconnecting the wires at the screw terminals. This effectively cuts off power at the doorbell. It is important to label or photograph the wires to ensure correct reconnection later.
2. Mounting the Doorbell
The Nest Hello should be mounted at a height that allows for clear visibility of visitors. A recommended height is 40–50 inches (approximately 4 feet) from the ground. This ensures that the camera captures full facial recognition and reduces blind spots.
To mount the doorbell, follow these steps:
- Use the wall plate provided in the box as a template to mark the drilling points.
- Drill a large hole (9 mm or 11/32 inch) through the middle hole in the wall plate. This allows for wire clearance.
- Drill two smaller holes (2 mm or 3/32 inch) for the screw mounts at the top and bottom of the wall plate.
- Ensure that the power to nearby devices—such as porch lights—is turned off before drilling to avoid electrical hazards.
Once the wall plate is mounted, attach the Nest Hello to the wall plate using the provided screws.
3. Connecting the Power Source
The Nest Hello can be powered either through a traditional doorbell transformer or via an indoor power adapter. The latter is particularly useful for users without an existing chime or doorbell wiring.
To connect an indoor power adapter:
- Plug the adapter into a standard electrical outlet.
- Connect the terminals on the back of the Nest Hello to the wire ends of the power adapter.
- No specific wiring configuration is required—either wire can be connected to either terminal.
It is important to note that the Nest Chime Connector included in the box is not necessary for this setup. Additionally, the doorbell does not require hardwiring or a separate transformer when using the indoor power adapter.
4. Configuring the Nest App
After the doorbell is mounted and powered, the next step is to configure it using the Nest app. The app provides a guided setup process that includes the following steps:
