Wondering if you can use a Nest doorbell without an existing doorbell?

It is possible to install a Nest Hello doorbell without any existing bell or wiring. We will cover the installation process for a Google Nest Doorbell without a pre-existing doorbell.

Compatibility and Requirements

Phone and Wi-Fi Requirements

When using a Nest doorbell without an existing doorbell, it is essential to ensure compatibility with your phone and Wi-Fi network. Nest doorbells work best with strong and stable Wi-Fi connections. The following are some requirements to consider:

  • A compatible phone running on iOS or Android OS
  • Wi-Fi network operating on 2.4 GHz or 5 GHz bandwidth
  • Nest App installed on your phone for set up and control

Voltage and Wiring

Nest doorbells can be used without an existing doorbell by installing the Nest doorbell (battery) model or using an indoor power adapter for the Nest Hello model.

These options eliminate the need for existing doorbell wires or transformer.

The Nest doorbell (battery) comes with a built-in rechargeable Li-Ion battery, making installation much more straightforward.

For those looking to use existing wiring for chime and recharging, ensure the voltage is within the recommended range for Nest doorbells.

Google Assistant Integration

Integration with Google Assistant is possible, adding convenience and versatility to your Nest doorbell experience. The following are some benefits of integrating Google Assistant:

  • Voice control over the doorbell functions
  • Access to live video feed and notifications on compatible devices
  • Integration with other smart home devices in your ecosystem

To use Google Assistant with your Nest doorbell, make sure you have a compatible Google Assistant device, such as a Google Home Mini or Google Nest Hub. Then, link your Nest account to your Google Home app and enable the necessary permissions for a seamless experience.

Using a Transformer

A transformer can be utilized to power the Nest doorbell if there is no existing doorbell.

The transformer will convert the mains voltage to a suitable low voltage for your Nest doorbell.

It’s essential to choose a suitable transformer based on the voltage requirements of your device, so that it can function correctly.

Indoor Power Adapter

If there is no existing doorbell, an indoor power adapter can be used to power the Nest doorbell.

This adapter is connected to your doorbell and plugged into an indoor power outlet. To install the adapter, follow these steps:

  1. Connect the adapter to your doorbell and plug it in.
  2. Connect the adapter wire ends to the wire terminals on the back of your doorbell.
  3. Remount your doorbell.
  4. Plug in the adapter into an indoor power outlet.

If desired, you can also install clips to neatly place the adapter cable along the wall.

Chime Compatibility and Options

Existing Chime Integration

The Nest Doorbell can work with pre-existing chime wiring if it is connected to the device to power it.

Once powered, you can choose to utilize either the existing indoor chime or have your Nest/Google smart home devices prompt the sound directly.
