The Leeo alarm monitoring system will monitor the temperature and humidity in any room in your home, and will send alerts to your smartphone. The app will also send you notifications and will even call you when smoke or carbon monoxide alarms sound. If an alarm does happen to sound in your home and the Smart Alert Nightlight can’t get a hold of you, it’ll alert your friends using the backup contact list that you create.
