Smoke, carbon monoxide, and weather

The Halo+ senses smoke and carbon monoxide. You can also customize which weather notifications you'd like to receive.

Rapid alerts

As you'd expect from a smart smoke detector, Halo+ has an iOS and Android app, and it'll send you an alert when it smells smoke. You can also silence the alarm with the app.

Weather options

And don't worry, the weather alerts won't cause the alarm to go off every time it rains. In fact, Halo+ has lots of options for customizing your alerts.

An easy-to-use app

When it's not an emergency, you can use the app to change the color of your accent light, check on the battery of the smoke detector, and see a log of activity.

The accent light

You can even use Amazon's Alexa assistant to control the accent light with your voice. You can change its color and brightness.
