Technologies & Capabilities
Responsive Motion Detection For Daily Automations
The sensor uses a high-quality PIR module to detect movement quickly, making it ideal for lighting, security, and occupancy-driven routines.
Built-In Ambient Light Sensing
With accurate lux measurements, the P2 helps automations respond to real-time lighting levels so lights activate only when needed.
Thread Connectivity With Matter Support
The sensor connects through Thread, creating a fast, low-power, and stable network that integrates easily with Matter-enabled smart home platforms.
Flexible Mounting For Optimized Coverage
Its compact design and adjustable base allow placement on walls, shelves, or corners to achieve optimal coverage in hallways, rooms, or entry areas.
Aqara Motion & Light Sensor P2 vs. P1
| Detection Range & Accuracy | Uses PIR motion detection with a wide 170° field of view and up to a 7-meter detection range. Adds built-in ambient light sensing for more accurate lighting automations. |
Offers up to a 7-meter detection range with a 170° field of view. Features dual-element PIR sensing with adjustable sensitivity for reduced false alarms. |
|---|---|---|
| Light Sensing & Automation Context | Includes a lux sensor that allows automations to react to real-time brightness, ensuring lights activate only when needed. |
Does not include a built-in light sensor. Automations rely on motion only unless paired with a separate lux-measuring device. |
| Connectivity & Protocol | Connects over Thread and supports Matter, allowing broad compatibility with Apple Home, Google Home, Alexa, and ecosystem Matter controllers. |
Uses Zigbee 3.0, offering a stable mesh network connection with low latency and strong battery efficiency when paired with Aqara hubs or Zigbee coordinators. |
| Mounting & Placement | Includes a magnetic base with angle adjustment for flexible placement on walls, shelves, or corners. Designed for fast Thread pairing in rooms with proper controller coverage. |
Also includes a magnetic stand with full rotation and tilt adjustment. Known for wide placement flexibility and excellent performance in Zigbee mesh environments. |
| Power Source | Powered by a CR2450 coin-cell battery with efficient Thread operation. Battery life varies based on motion frequency and Thread network activity. |
Powered by two CR2450 batteries with up to five years of life under typical use, benefiting from Zigbee’s low-power design and configurable detection interval. |
| Platform Integration | Integrates through Matter, enabling native support across major platforms as long as a Matter controller with Thread is present. |
Works with Aqara Home, Home Assistant, Apple HomeKit, Alexa, and SmartThings through Zigbee integration or an Aqara hub. |
| Additional Capabilities | Supports lux-based automations, Thread mesh participation, Matter interoperability, and improved responsiveness in supported ecosystems. |
Includes adjustable motion detection intervals, sensitivity control, and a long battery life focus, making it reliable for high-traffic areas or whole-home deployments. |
Frequently Asked Questions
How to reset Aqara Motion & Light Sensor P2?
To reset the P2, press and hold the pairing button for a few seconds until the indicator light starts flashing. Once it flashes, release the button and the sensor will enter pairing mode so you can reconnect it to your Matter-enabled platform or Thread network. If the sensor remains unresponsive, remove the battery for a moment, reinsert it, and repeat the reset process.
Where should I install the Aqara Motion & Light Sensor P2?
Common locations include hallways, bedrooms, bathrooms, entryways, and living spaces where motion or lighting-based automations are useful.
How do I use the "Detection Time Interval"?
Detection Time Interval controls how quickly the sensor reports new motion events after the previous one. A shorter interval creates more responsive automations but may use more battery power. A longer interval reduces reporting frequency to conserve battery while still supporting standard lighting or activity-based routines. Adjust this setting based on how frequently you need the sensor to detect and report motion in your space.
Does the P2 require a hub?
No Aqara hub is required. The sensor connects through Thread and works with compatible Matter controllers from supported platforms.
Can the P2 trigger lighting automations?
Yes. With built-in lux sensing, it can activate or adjust lights based on both motion and current brightness levels.
