With Nest Hello, you can watch everything that is happening just outside your door.

It broadcasts live to your phone at all times, and you can get a three-hour snapshot if you want to check in on what’s happening on your doorstep throughout the workday. Nest Hello is unobtrusive, functional, and an excellent complement to your home’s security system.

How to Install and Use Google NEST Hello Doorbell Without Existing Doorbell

Without an existing doorbell, all you need to do is drill a few extra holes where you want the Nest Hello to be and buy an indoor power adapter for the Nest Hello. If you want to install a Google NEST Hello doorbell without an existing doorbell, follow this step by step guide.

A lot of doorbells are about 4 feet (or 1.2 meters) high. So, hold the Nest Hello’s wall plate against the wall to make a mark for where the power adapter’s wires will come through. The hole should be in the middle of the main hole in the wall plate and in the bottom half.

It’s important to turn off the power to your home’s breaker box, especially in the places where you plan to plug the Nest Hello in. Your home’s indoor plumbing and electrical wiring should also be known. The building codes where you live should have this information, and this will make it safe to put the Nest Hello in your house, so you can do it.

Decide if you want to use the Nest Hello wedge that comes with it. Useful if you think the camera on the doorbell won’t be able to see what’s going on at your doorstep. Stick it on the back of the wall plate.

Drill a hole for the wires from the power adapter. We’ll start at the beginning. This is where you marked in step 1. It’s important to start by drilling two pilot holes above and below where the wires go. You’ll use these to put the wall plate on. Take care to make sure the Nest logo is at the bottom, and screw the top hole in first. Make sure the wall plate is straight before you screw in the bottom hole. This will let you do this.

A grommet should slip over the adapter cable before you run it through the hole to the outside. Then, connect it to your Nest Hello. No matter which wire goes to which terminal, you should make sure that all cables point down so that any extra can be shoved back through the wall.

When you’re done, you can put Nest Hello on the wall plate. It should push itself in with a click. The wire should be tucked behind the hole if it doesn’t fit. Nest Hello will start up and be ready to use when you plug in the adapter.
