First, it’s essential to understand the different parts of the Nest doorbell. There are three main components: the chime box, the power adaptor, and the faceplate. The chime box is a small device that connects to your existing doorbell wires to connect your doorbell and your Wi-Fi network. The power adapter plugs into an outlet near the doorbell and provides power for the doorbell itself. At the same time, the faceplate acts as a protective barrier between the outside world and your home’s internal wiring.

To begin the installation, shut off power to your existing doorbell at your circuit breaker panel or fuse box. Then remove any current doorbell button or cover plate from its mounting screws on either side of the entryway. Once these have been removed, please take note of any exposed wires inside so you can properly connect them to their corresponding terminals on the chime box later in this process.

Please see the video:

Next, mount the chime box near where you removed your old doorbell hardware using screws or double-sided tape, depending on what material makes up your entryway wall (i.e., drywall versus brick). Connect each wire from your entryway to its corresponding terminal on the chime box, ensuring each wire has been appropriately secured before connecting it to your Wi-Fi network via Bluetooth or Wi-Fi Protected Setup (WPS).

To install Nest Hello, the essential requirement is to adjust and set the voltage to ensure the doorbell’s properly working. If you already have a properly battery-based doorbell, install wires and chimes before setting up Nest. However, if there is no doorbell or an intercom system, you will be expected to contact and ask for Nest Pro help. This will be the first step in figuring out the rest of the installation process of Nest Hello. If you have a doorbell, the process gets trouble-free as you need to set up the voltage.

According to their official website, the wires will be compatible if there are two or more wires. Even though it is battery-powered, it does not mean it would not be functional at all. As long as there are wires, there is a good chance of compatibility. An electrician will be required to set up the wiring system to associate with Nest Hello. The wiring should have T, F, and R marked to understand the installation process. Without any labels on the wiring, help would be needed from Nest Hello or professionals. Once you have determined whether you have wires, the next step would be to deal with the voltage professionally.

There are three main ways to check the voltage.
1. Using a millimeter
2. Asking a professional
3. Finding the transformer’s voltage.

If you avoid hassle work, you can contact Nest Pro or a local electrician who will quickly check the voltage. As professionals, they will figure out voltage and install Nest Hello if you avoid too much work. It will add a bit to the cost but allow you to stay under budget, saving time and extra effort.


Finally, after ensuring everything is connected correctly, you can install the power adapter and faceplate for the Nest Doorbell. Begin by attaching one end of an included extension cord to a weatherproof outdoor outlet located within five feet of where you will be mounting your Nest Doorbell, then plug in and attach it into place, securing it with screws if necessary before screwing in its faceplate with provided mounting screws until firmly attached in area.

With all three pieces securely installed now, all that’s left is to set up and configure it using Nest’s app on iOS or Android for additional features like motion detection notifications, etcetera. Once connected successfully, you’re all set!
