Wonderful way to watch over your home anytime, anywhere while home or away via the Notion App and the notion sensors provide a great peace of mind, from your smoke alarms, to thermostat settings, open doors or windows and water leaks. Our water leak sensors have saved us a couple of times. Thank you Notion!!

Smoke and carbon monoxide alarms are great, if you’re there to hear them...
What if you have pets at home, how will you know if there’s a possible threat?
By installing a Notion Sensor near your UL-listed smoke or CO alarm, you can receive an alert on your smartphone when the alarm sounds so you can take action.
*This device does not detect fire, smoke or carbon monoxide and is intended to listen for only UL-listed smoke and CO alarms that are fewer than 10 years old.
Setting up your Notion Sensor is quick and easy.
No hardware required, professional installation or monthly fees!
