Retrofit your garage door opener for Wi-Fi

An open garage door at night is the way in. Keep your opener. Add a small box that tells your phone the door is closed, closes it, and says when it was left open.

What you get

It wires to the opener you have. Nothing runs on a battery: set it up once, and there is nothing to charge or replace.

When the internet is out

On your home Wi-Fi, the app talks to the box directly. The door still opens and closes from your phone, and it carries on when the connection comes back.

With CO

SafeGarage with CO opens the door a little when carbon monoxide rises while a car warms up on a winter morning. A ventilation helper, not a CO alarm; keep a certified alarm in your home.
