My original doorbell ringer was on a wall 90 degrees from the door. Additionally, it was installed with an electrical outlet box. The Nest Hello didn’t come with the needed hardware for this situation. The AirTech Kit perfectly resolved this situation. I could use the existing electrical outlet box, and drilling was not required; just screw drivers. And the camera view is perfect! What a simple install with this kit. This should be standard hardware with the Google Nest Hello.

Very nice wall plate. Good size to cover old holes to side, but not too big like others I saw online
