$20 – $30
Zigbee motion sensor with 15ft range, temperature monitoring, and magnetic ball mount for SmartThings ecosystem.
You want small discreet design
Compact form factor. Easy installation. Blends into environment. Multiple mounting options.
You need immediate phone alerts when motion detected
SmartThings app notifications when motion detected. Good for security monitoring when away or sleeping.
You want motion + temperature in one sensor
Dual function: detects motion and monitors room temperature. Good for HVAC automations triggered by occupancy.
You have SmartThings Hub and want native motion sensing
Seamless SmartThings integration. 120° FOV, 15ft range. Built-in temperature sensor. Official Samsung sensor.
You expect long battery life
Notorious battery drain issues. Some users report 2 weeks to 1 month battery life instead of months.
You do not have SmartThings Hub
Requires SmartThings Hub (Zigbee). Cannot work standalone. Other ecosystems may have better options.
You need superior range or ceiling mounting
15ft range disappointing for some. Ceiling mount only detects motion directly below. Consider Zooz or Aeotec.
Batteries drain in 2 weeks to 1 month instead of expected months. Chronic issue across multiple forum reports.
SmartThings CommunityAfter battery swap, sensor stops detecting motion while temperature still works. May need re-pair.
SmartThings Community15-30 second delay before sensor sends "no motion" event. May affect time-sensitive automations.
SmartThings CommunityBattery level readings fluctuate wildly - 60% one day, 80% next, then 30%. Unreliable battery status.
SmartThings CommunityExtremely short battery life (weeks instead of months)
widespreadCause: Poor power management. Excessive Zigbee polling or mesh issues suspected.
Battery level readings wildly inaccurate
commonCause: Fluctuates between 30-80% randomly. Cannot trust battery status.
Limited 15ft range disappointing for larger rooms
commonCause: PIR sensor design limitation. Ceiling mount makes it worse.
Motion detection stops after battery change
occasionalCause: Zigbee pairing issue. May need to re-add sensor to hub.
Device stops working after few weeks
occasionalCause: Hardware failure or battery drain. Replacement may be needed.
Expecting long battery life
Constant battery replacements. Frustration with short lifespan.
Tip: Stock up on CR2450 batteries. Some users switch to lithium for longer life.
Mounting on ceiling for wide coverage
Only detects motion directly below. Poor coverage from height.
Tip: Wall mount at 6-7 feet height facing room center for best coverage.
Trusting battery percentage readings
Sensor dies unexpectedly. Battery shows 60% then dies.
Tip: Replace batteries on schedule regardless of percentage. Keep spares.
All functionality through SmartThings cloud. Automations, alerts, history.
Very limited. Basic Zigbee communication but most features require cloud.
Motion events, temperature readings, timestamps. Samsung SmartThings cloud.
Samsung cloud dependency. Data processed remotely. Simple sensor - no audio/video.
Tested with up to 100 devices
120° FOV, 15ft range. CR2450 battery (poor life). Includes temperature sensor. Zigbee mesh.
Requires SmartThings Hub. Battery life 2 weeks to 1 month typical. 15-30 second no-motion delay.
Aeotec SmartThings Motion Sensor
If: Want SmartThings compatible with better reliability
Zooz Z-Wave Motion Sensor
If: Need longer range and better battery life
Aqara Motion Sensor P1
If: Want HomeKit with better battery life
You have SmartThings and want basic motion+temp sensing
Native SmartThings integration. Temperature bonus. Accept battery drain as trade-off.
You expect long battery life
Battery issues are widespread and well-documented. Expect 2 weeks to 1 month, not months.
You need reliable security-grade motion detection
Too many reliability issues. Consider professional security sensors instead.
You want to automate lights based on room occupancy
Works for basic occupancy automation. 15-30 second reset is acceptable for most use cases.
Common issue. May need to re-pair sensor with SmartThings Hub. Remove and re-add device in app.
