Product Description

Entering the Matter Era

The P2 supports Matter natively, and connects directly to the most popular ecosystems and Aqara Home in the near future through the Matter-compatible Aqara Thread border router*.

Why Thread Protocol?

What is required?

Matter Controller or Thread Border Router Support:

To add the P2 to a particular Matter-enabled app, your device or devices will need to have both functionalities, therefore a 2-in-1 Matter Controller & Thread Border Router is needed as a minimum requirement.

Always-on Open/Close Detection

Stay informed and secure with real-time notifications on your smartphone whenever the sensor detects activity. You’ll never miss a potential security threat, whether you’re at home or away.

By installing the P2 on a first aid kit, medical professionals can monitor when it is opened, ensuring that it is used appropriately and restocked when necessary.

The P2 can also be placed on a safe box in a home or office to alert owners if it is opened by unauthorized personnel, preventing the loss of important documents, cash, or valuables.

Maximizing Efficiency with Voice Assistants

You can receive alerts, or ask about whether a door is open, keeping you on top of things at home.

The sensor is easy to install with its strong sticker and an alternative flat magnet.

Equipped with a powerful CR123A battery, it provides uninterrupted protection.

Additional Features via OTA

Settings through the Aqara Home app will be expanded with the future launch of the Hub M3

[Native Matter Support over Thread] As one of the first sensors to support Matter, the P2 supports access to Apple Home, Google Home, Amazon Alexa and Samsung SmartThings. Meanwhile, as a sensor based on the Thread protocol, the P2 provides enhanced connectivity, low-power consumption, more stability and low latency.
[Open/Closed Status Monitoring] With a built-in high-precision Hall sensor, the Aqara Door and Window Sensor P2 can detect the opening and closing status of doors, windows, and drawers precisely. Once the sensor is triggered, it will send real-time alert notifications to your smartphone whether you’re at home or away, ensuring you’re always aware of any potential security concerns. (*Note: the functionality such as automation conditions may vary throughout the different ecosystems.)
[Local Home Automations] You can integrate the Door and Window Sensor P2 with your smart home ecosystem to enable advanced automations like adjusting thermostat settings or activating security cameras when a door or window is opened. Moreover, the automations are executed without the cloud, which can protect the user’s privacy and will keep working even if there is no internet connection.
[Voice Alerts and Status Notifications] The Aqara Door and Window Sensor P2 supports Apple Siri, Alexa, and Google Assistant. With these voice assistants, you can receive alerts about events such as door entries, or ask whether a door is open, allowing you to effortlessly monitor your home.
[Matter Compatibility] A Matter Controller & Thread Border Router 2-in-1 is required to enjoy seamless integration with a Matter-enabled smart home ecosystem. Currently, the following hubs are tested, but new hubs will be added over time. Apple: Apple TV 4K (3rd gen, 128 GB), Apple TV 4K (2nd gen), HomePod (2nd gen), HomePod mini | Samsung: SmartThings Hub v3, Aeotec Hub v3, SmartThings Station | Amazon: Echo (4th gen) | Google: Nest Hub (2nd gen), Nest Hub Max, Nest Wi-Fi Pro.
