$35 – $45
Zigbee motion sensor with 100° FOV and 5m range. Built-in daylight sensor. Requires Hue Bridge. Works with HomeKit, Alexa, Google.
You want ambient light detection for smart automations
Light sensor prevents lights from turning on during day. Only triggers when dark enough. Smart daylight awareness.
You need temperature sensing with motion
Built-in temperature sensor exposed to HomeKit. Can trigger HVAC automations. Unique feature among motion sensors.
You want the most reliable motion sensor for lighting
Zigbee mesh is rock-solid. 2-year battery life on AAA batteries. Magnetic mount for easy repositioning. Ultra-fast response.
You already have Philips Hue lights and Bridge
Seamless integration with Hue ecosystem. Lightning-fast automation. Temperature sensor exposed to HomeKit. Best Hue companion.
You do not have a Philips Hue Bridge
Requires Hue Bridge ($60+) to function. Cannot work standalone. Consider Eve Motion for hub-free Thread/Bluetooth.
You need wide-angle coverage (170°+)
Only 100° field of view. Aqara P1 offers 170° fully rotatable. May need multiple Hue sensors for large rooms.
You want the cheapest option
At ~$45, more expensive than Aqara (~$25). Premium for Hue ecosystem integration. Aqara is better value.
Integration can get stuck on "no motion detected" even when working in Hue app and Google Home.
SmartThings CommunityAfter turning Hue light on/off via Home Assistant, motion sensor stops triggering until bridge resyncs.
Home Assistant CommunityLimited 100° field of view compared to competitors
widespreadCause: Hardware design choice. Aqara offers 170° for comparison.
Requires Hue Bridge - no standalone operation
widespreadCause: Zigbee device needs hub. Bridge adds $60+ to initial cost.
Buying without Hue Bridge
Sensor is useless without Bridge. Cannot pair or function.
Tip: Ensure you have Hue Bridge before purchasing. Required for all Hue accessories.
Not updating scenes after adding new bulbs
New bulbs ignore motion sensor triggers. Only original bulbs respond.
Tip: Update motion sensor scenes in Hue app after adding any new lights.
Remote access via Hue app when away from home. Voice control via Alexa/Google.
Motion-triggered lighting works locally via Bridge. HomeKit automations run locally. No cloud needed for basic function.
Tested with up to 50 devices
100° FOV, 5m (16ft) range. AAA batteries last up to 2 years. Includes light sensor and temperature sensor. Magnetic mount.
Requires Hue Bridge. Max 50 accessories per bridge. Narrower FOV than competitors. Indoor use only (outdoor model separate).
Aqara Motion Sensor P1
If: Want wider FOV (170°) and cheaper price
Eve Motion
If: Want Thread/Matter without a hub
Philips Hue Outdoor Motion Sensor
If: Need outdoor or weatherproof motion detection
You already own Hue Bridge and lights
Seamless integration, fast response, reliable Zigbee. Temperature sensor bonus. Best companion for Hue system.
You are starting fresh with no smart home hub
Requires $60+ Bridge on top of sensor cost. Eve Motion or Aqara are better starting points.
You need wide coverage for large open rooms
100° FOV is limiting. Consider Aqara P1 with 170° FOV or use multiple Hue sensors.
Motion sensor controls scenes, not individual lights. Update the scene in Hue app to include new bulbs.
Source: Hueblog TroubleshootingYes, includes temperature sensor exposed to HomeKit. Can trigger automations based on room temperature.
Source: HomeKit IntegrationNew lamps added to system may not respond to motion sensor until scenes are updated to include them.
HueblogSensors occasionally stop working entirely. Usually fixable with battery removal and re-pair. Firmware updates help.
Multiple ForumsSensor stops responding until battery pull/re-pair
occasionalCause: Zigbee mesh issues or firmware bugs. Usually fixable with reset.
Higher price than Aqara alternative
commonCause: Premium Hue ecosystem pricing. $45 vs $25 for similar function.
New bulbs not triggered until scenes updated
occasionalCause: Motion sensor controls scenes, not individual lights. Must update scenes.
Placing sensor where 100° FOV is insufficient
Motion not detected from sides. Lights fail to trigger.
Tip: Place sensor to cover main traffic flow. May need multiple sensors for large rooms.
Motion events, temperature, light levels. Stored locally on Bridge. Cloud sync optional.
Simple sensor - no audio/video. Local Bridge operation available. Cloud features optional.
You want temperature-based automations
Built-in temperature sensor exposed to HomeKit. Trigger HVAC or fans based on room temp.
Up to 2 years on 2x AAA batteries. Easily replaceable. Low power Zigbee protocol extends life.
100° field of view with 5 meter (16 feet) detection range. Narrower than Aqara P1 (170°).
