📡 Quick Picks
Why Matter Smart Sensors?
Smart sensors are the eyes and ears of your smart home. They detect motion, monitor doors and windows, track air quality, and alert you to water leaks — all automatically triggering actions across your entire smart home ecosystem.
With Matter, your sensors work with Apple HomeKit, Amazon Alexa, Google Home, and Samsung SmartThings simultaneously. A single Eve Motion sensor can trigger a HomeKit scene, an Alexa routine, AND a Google Home action — no duplicates needed.
What We Look For
- Matter certification — verified CSA Matter certified for universal compatibility
- Response speed — Thread sensors respond faster than Wi-Fi or Bluetooth
- Battery life — sensors should last 1-5 years on a single battery
- Detection accuracy — no false positives, no missed events
- Build quality — compact, discreet, and durable

Water damage is the most expensive home disaster that sensors can prevent. The Shelly Flood Gen4 is one of the first Matter-certified leak sensors, and at $30 it's cheap insurance for under sinks, behind toilets, near water heaters, and in basements.
Smart Sensor Buying Guide
Motion vs. Presence Sensors
Traditional motion sensors (PIR) detect movement — great for triggering lights when you walk into a room. But they can't tell if someone is sitting still. Presence sensors (mmWave radar) detect even stationary people by sensing micro-movements like breathing. If you want lights to stay on while you're reading in a chair, get a presence sensor.
Thread vs. Wi-Fi vs. Bluetooth
For sensors, Thread is the clear winner. Thread sensors use minimal power (years of battery life), respond instantly through mesh networking, and don't congest your Wi-Fi. Wi-Fi sensors drain batteries faster but don't need a hub. Bluetooth sensors have short range and often need a nearby bridge device.
Where to Place Sensors
- Motion sensors: Hallways, staircases, room entrances at 6-7 feet height angled downward
- Door/window sensors: All entry points, garage doors, medicine cabinets, gun safes
- Presence sensors: Living rooms, offices, bedrooms — anywhere people sit still
- Water leak sensors: Under sinks, behind toilets, near water heaters, by washing machines
- Air quality sensors: Main living area, bedrooms, near kitchens
How Many Sensors Do You Need?
Start with the high-impact placements: front door contact sensor, main hallway motion sensor, and one water leak sensor near your water heater. Then expand room by room. Most homes benefit from 5-10 sensors total. The IKEA MYGGBETT at $12 makes it affordable to cover every door and window.
