## Description

Aqara Door and Window Sensor P2

Review: This is one of the easiest sensors to setup in my Home Assistant ecosystem. Bought one and quickly bought a second one after seeing how reliable and easy it was. One is used on our balcony door (setup on the 90 degree corner where the glass door meets the wall) to ensure that if we go to leave the house without closing it, our home will tell us. Works like a charm and has given us peace of mind the cats are safe! When I saw how sensitive these are, I bought a second one for a snack cupboard. I placed the sensor on the inside of the cupboard doors and now if the cupboard is opened even a sliver, the home counts how many times, and gives a snarky AI generated comment if it's too high haha. These sensors are easy to forget about which is the idea, they're out of sight but they diligently keep an ever vigilant eye on things. happy to report that the battery is still 100% after 2 months! Will be buying more I'm sure.
Review: J’utilise principalement HomeKit, avec des appareils de différentes marques, et ce détecteur de porte Aqara P2 s’intègre parfaitement grâce à Matter. L’appairage est simple et rapide, et le capteur est immédiatement reconnu dans HomeKit sans difficulté. La détection est très réactive, aussi bien à l’ouverture qu’à la fermeture, ce qui le rend idéal pour les automatisations (notifications, éclairage, alarmes, etc.). La compatibilité Matter est un vrai avantage, car elle permet d’utiliser le capteur avec un écosystème multi-marques tout en conservant une excellente stabilité. Le capteur est discret, bien fini et inspire confiance côté qualité. Points positifs : ✔️ Compatibilité HomeKit native via Matter ✔️ Fonctionne parfaitement dans un écosystème multi-marques ✔️ Installation simple et rapide ✔️ Détection fiable et instantanée ✔️ Design discret et bonne qualité de fabrication Points négatifs : ❌ Nécessite un hub compatible Matter / Thread ❌ Un peu plus cher que les capteurs non Matter Conclusion : Un excellent détecteur de porte pour les utilisateurs HomeKit qui veulent une solution fiable, moderne et compatible avec plusieurs marques grâce à Matter. Très satisfait de ce produit.

## Features

- [Native Matter Support over Thread] As one of the first sensors to support Matter, the P2 supports access to Aqara Home, Apple Home, Google Home, desertcart 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. Aqara Home(Hub M3), 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 | desertcart: Echo (4th gen) | Google: Nest Hub (2nd gen), Nest Hub Max, Nest Wi-Fi Pro.
- [Easy Installation & Long Battery Life] With its compact design and adhesive back, the sensor is easily integrated into any interior. Additionally, equipped with a powerful CR123A battery, it provides uninterrupted protection with infrequent replacements.* The battery life may vary depending on the border router and Matter app the sensor is connected to. For best results, the future Aqara border router is advised.
