What's interesting about Leeo is that I'm betting you could also use it to listen for other connected alarms - Piper, which I reviewed back in April of 2014, watches for motion and then sets off an earsplittingly loud siren if it sees it.

Easy to install, low-tech, with in-home monitoring for some crucial, but simple details, Leeo is a solid choice for those looking to tip some ease of mind into their daily routine.

The Leeo Smart Alert Smoke/CO Remote Alarm Monitor is a sleek, easy-to-use device that “listens” for your existing smoke and carbon monoxide alarms and sends notifications to your phone.

It also makes this unit particularly appealing to people who want to monitor vacation homes or are away on long trips.

It is just easy to set up it as you just need to plug in and then connect it to your place Wi-Fi.

What experts didn't like
Customer reviewers report alarm won’t pick up on signals from older smoke detectors.
- BestReviews
One thing I was kind of surprised with was the lack of IFTTT integration for Leeo, considering that most other connected devices seem to jump on the IFTTT bandwagon.

Not a big issue, but a glitch in the programming as far as I was concerned.

The app suffers from a few bugs, however, and in the event of an emergency, the alerts won't do much to help you figure out what's actually going on.

Apart from the false alarms, I have only two other criticisms: First, Leeo doesn’t have any provision for being incorporated into other smart-home systems.

One issue mentioned by several customers is a tendency for other sounds to trigger Leeo.
