Brighten up your old smoke detector with the Leeo Smart Alert Nightlight (pictures)

The Leeo Smart Alert Nightlight combines a color-changing glow you can control with your iPhone with a smart sensor that listens for your smoke alarm and carbon monoxide detector and alerts you when something is wrong.

The nightlight plugs into a standard outlet.

The compact shape means it won't block the other plug.

Once it's plugged in, you'll see it start to glow.

You can control the color via the iOS app.

Just drag the icon to the color you want.

The nightlight casts a warm, bright glow.

You can control the brightness with the outer ring of the front face, or with the app.

If an alarm sounds, the light blinks red. You'll also get a push notification, followed by a phone call.

The Leeo Smart Alert Nightlight also detects humidity and temperature. You can customize alerts for these as well.

Leeo has a 75-foot (23-meter) listening range. Place it in the hallway so it can hear multiple rooms.

Setting it up on Wi-Fi is as simple as it gets. Plug it in, open up the app, and enter your network information.

The Leeo Smart Alert Nightlight helps you monitor your home from wherever you are.
