Water Leaks

Water is the biggest threat to a home, even compared to fire and theft! Knowing the second a leak breaks out can mean the difference between a mop and a basement remodel.

  • Toilets
  • Water Heaters + AC Units
  • Sinks
  • Showers + Bathtubs
  • Appliances
  • Leaky Pipes

Water Leak Detector


Know when people (or pets!) are coming, going, getting into things they shouldn't, or even delivering your mail!

  • Front / Back Door
  • Sliding Doors
  • Garages
  • Gun Safe
  • Liquor Cabinet
  • Mail Boxes

Garage Door Monitor


What good is an alarm if you're not home to hear it going off? Place a sensor near your smoke or carbon monoxide alarm to receive an alert the moment it sounds.

  • Smoke
  • Carbon Monoxide

Smart Smoke and CO Detector


Just place a sensor directly on the glass and Notion will alert you if your window opens. This feature is perfect for a higher level of security without the cost.

  • Sliding Windows
  • Hinged Windows

  • Wine Cellars
  • Music Rooms

Notion also integrates with Nest Learning Thermostat™
