Customer Reviews

Michael, CO

"Some time back we had a water leak in our laundry room which caused damage to our wood floors. We have since placed a notion detection device in the laundry room. It recently detected a water leak from our washer. Thankfully we were able to turn off the water and get our washer repaired before we encountered any damage. We also have the devices on our entry door, garage door, and kitchen door. I would certainly recommend them to anyone wanting monitoring devices for their home."

Chris, MD

"Twice since first getting Notion, it alerted us to an HVAC failure with its temperature threshold alarms. In both situations, once with us on the other side of the country, we were able to get someone home to move our temperature-sensitive pets to a safe location and have the system repaired very quickly. It saved the lives of our pets, and lets us rest easy while away from home!"
