Here is a handy device that monitors your smoke and carbon monoxide detector and alerts you on your smartphone when things are not quite right. The Leeo Smart Alert Nightlight does not require you to sign up for a contract to get started. It monitors temperature and humidity in any room and sends notifications to your phone. It can also call your phone when smoke or carbon monoxide alarms sound.
Did we mention that this is a pretty decent nightlight with 16m color options for you to choose from? You can always rely on backup contacts if for some reason you can’t answer your phone. The device sets you back $99 at this time.
