Review: Excellent Door and Window Sensor that works well in Home Assistant and HomeKit - I needed to replace a door and window sensor and thought I'd give this one a try, since it's Matter over Thread. While the sensor is a little bigger than I'd like, it sits high up on a door and doesn't stick out much. I forget it's there now. I added the sensor directly to HomeAssistant (because I have HA set up in my Thread network already) and it added quickly without any hiccups, so it's definitely possible. I did have to replace the battery it came with, since I think the battery had drained while sitting in the box, but that wasn't a big deal. The sensor works great and I would definitely buy another one. Whenever possible I prefer Matter over Thread or Z-Wave devices for use in Homekit to keep 2.4GHz interference down and to keep IoT devices off my wi-fi network, taking up IP addresses. This one was a good buy and I recommend it IF you already have a thread border router. If you don't use Home Assistant and just use HomeKit, I still recommend it because I was able to pair it with HomeKit and it worked flawlessly. I have an AppleTV 4k and a few HomePod minis as border routers, so your mileage may vary.
Review: Aqara P2 Contact Sensor – Disappointing Reliability for a “Next-Gen” Matter Device - I’ve been a long-time Aqara customer with over 35 Aqara products at home — including switches, cameras, and sensors. The original Aqara Zigbee contact sensors have worked flawlessly for years. That history of reliability is what led me to purchase four Aqara P2 Contact Sensors, which use Matter over Thread. Unfortunately, the P2 has failed to meet expectations. Constant Disconnections: After just a few months, the P2 sensors started disconnecting from Apple Home. Unlike Zigbee devices, which reconnect automatically after outages, the P2 requires a manual factory reset and re-pairing. This means removing it from Apple Home and rebuilding every associated automation and shortcut. This disconnection occurs roughly every two months or after internet outages, even though Matter and Thread are supposed to be local protocols. Other Matter and Zigbee devices recover just fine — only the P2 fails consistently. Battery Drain Issues: One of my P2 sensors showed 0% battery. After inserting a new CR123A battery, it dropped to 25% within a day and 0% by the next. Another fresh battery dropped to 75% in minutes. I contacted Aqara support, who attributed it to residual power and advised removing the battery, holding the reset button for 5 seconds, then reinserting it. This did not resolve the issue. Poor Customer Support: Support requires emailing Aqara and waiting 3–4 business days between responses. After weeks of following scripted troubleshooting steps, they concluded that my device was out of warranty and that I would need to purchase a new one. Given the issue appeared after a battery change, this response was especially frustrating. Final Verdict: The Aqara P2 Contact Sensor is unreliable, difficult to reset, and not ready for real-world use. If you’re heavily invested in automations or HomeKit, you’re better off with: • Aqara’s original Zigbee contact sensors, which are far more stable • Or Eve’s Matter-compatible contact sensors, which have performed far more reliably The P2 is not worth the time or effort. Aqara’s implementation of Matter is still too immature for a critical-use sensor.

## 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 . Meanwhile, as a sensor based on the Thread protocol, the P2 provides enhanced connectivity, low-power consumption, more stability, and low latency. (**Note: 2-in-1 Matter Controller & Thread Border Router is required and sold separately)
- [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: To ensure a stable connection, place the Door and Window Sensor P2 main unit between the accessory unit is no more than 22 mm )
- [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: Hub v3, Aeotec Hub v3, | desertcart: Echo (4th gen) | Google: Nest Hub (2nd gen), Nest Hub Max, Nest Wi-Fi Pr
- [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. Please ensure to use a CR123A battery when replacing, as incompatible models may cause failure or malfunction.

### ⭐⭐⭐⭐⭐ I have several of these, and they have all worked flawlessly for me with Home Assistant
*by J***S on October 22, 2025*

I have not had any of the connectivity issues or reliability issues that some reviewers have had with this product. To date I have purchased 7 of these contact sensors, and they have all been rock solid, in fact theyve been some of the most reliable products in my smart home. If that changes I'll edit this review with an update. They all paired to Home Assistant using Matter quickly and without issue...except for one. One was actually giving me a decent amount of trouble with pairing. I ended up temporarily turning off my Wifi's 5Ghz network, factory resetting multiple times, and retrying multiple times, but it did eventually work, and that sensor has not given me any trouble since. The sensors are also pretty fast to update, and while it's a tad bulky for a contact sensor, the trade-off is that i've gotten great battery life out of them so far. I have no complaints
