$17 – $25
Wireless PIR motion sensor with 30ft range, light sensor, and 3-year battery life for smart home automation.
You need built-in light sensor
Includes ambient light sensor. Create automations based on motion AND light level. Trigger only when dark.
You want simple Bluetooth-based motion sensing
Works via Bluetooth out of box with SwitchBot devices. No hub needed for basic SwitchBot automations.
You already use SwitchBot ecosystem
Seamless integration with SwitchBot devices. Triggers automations for lights, blinds, curtains. Native app control.
You want affordable motion sensing with Matter option
Budget-friendly PIR sensor. Matter compatible with SwitchBot Hub. Works with Alexa, Google, HomeKit via hub.
You need Matter/HomeKit without additional hub
Requires SwitchBot Hub Mini (~$35) or Hub 3 for Matter/HomeKit. Sensor alone is Bluetooth only.
You need presence detection (stationary person)
Basic PIR only detects movement. Cannot detect stationary people. Consider newer SwitchBot Presence Sensor with mmWave.
You want the most capable motion sensor
Basic PIR sensor. 110° horizontal FOV. Not the fanciest option but affordable and functional.
Requires 30 seconds of no motion to recognize "no motion detected". May seem slow to reset.
SwitchBot SupportDevice status not updating in SmartThings reported in November 2024. Integration issues with third-party platforms.
SmartThings CommunitySome users report detection not working via Homebridge integration. Motion sensor status not changing.
Home Assistant CommunityBluetooth range limited to about 9 meters open-air. Walls reduce range. Hub extends reach.
Product SpecsRequires hub for Matter/HomeKit integration
widespreadCause: Sensor is Bluetooth only. Hub Mini or Hub 3 needed for Matter bridge.
30-second delay before no motion detected
commonCause: PIR sensor cooldown period. Cannot be adjusted. Normal for PIR sensors.
Limited 110° horizontal field of view
occasionalCause: Basic PIR design. Competitors like Aqara P1 offer 170° FOV.
Third-party integration issues (SmartThings, Homebridge)
occasionalCause: Bluetooth-to-cloud relay. Status updates may be delayed or missed.
No presence detection for stationary people
widespreadCause: Basic PIR only. Newer SwitchBot Presence Sensor has mmWave for this.
Expecting Matter/HomeKit without SwitchBot Hub
Sensor is Bluetooth only. Cannot expose to Matter without hub.
Tip: Purchase SwitchBot Hub Mini (~$35) or Hub 3 for Matter/HomeKit integration.
Installing at wrong height
Detection area misaligned. Motion not detected or excessive false positives.
Tip: Install at recommended height: 1.2-2 meters (4-6.5 feet). Angle sensor appropriately.
Expecting instant "no motion" status
Lights stay on longer than expected. Automations delayed.
Tip: Understand 30-second cooldown is normal. Design automations around this delay.
Remote access, voice assistants, third-party integrations require SwitchBot cloud.
Bluetooth triggers to other SwitchBot devices work locally. Motion detection itself is local.
Motion events, light levels. Sent to SwitchBot cloud for app history and remote access.
Simple PIR sensor. No audio/video. Cloud for remote features. Local Bluetooth available.
Tested with up to 4 devices
110° horizontal FOV, 55° vertical. ~9m Bluetooth range. Includes light sensor. Install at 1.2-2m height.
Hub Mini supports 4 devices via Matter. Hub 3 supports 30. Bluetooth only without hub. 30-second no-motion delay.
SwitchBot Presence Sensor
If: Need presence detection for stationary people
Aqara Motion Sensor P1
If: Want wider FOV and HomeKit without additional hub purchase
Eve Motion
If: Want Thread/Matter without any hub
You already have SwitchBot Hub and ecosystem
Affordable addition to SwitchBot setup. Matter via hub. Light sensor for smart automations.
You want Matter/HomeKit without buying a hub
Requires SwitchBot Hub Mini or Hub 3 (~$35-80). Eve Motion is hub-free alternative.
You need presence detection for room occupancy
Basic PIR only. Cannot detect stationary people. Get SwitchBot Presence Sensor with mmWave.
You want budget motion sensing with light sensor
Affordable with built-in light sensor. Create motion+dark automations. Good value.
No. Basic PIR detects movement only. For presence detection, get SwitchBot Presence Sensor with mmWave.
