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.

Five stars…after some issue resolutions
These are wonderful, but you have to do a few things if you’re having issues. I tried connecting one and it was not working at all. So I tried to set up another and the same thing happened.Since both were not working I figured it was something with my network. Turns out my mesh router (Google Nest Wifi Pro) was conflicting with my router (whatever ATT gave me). The ATT router had its WiFi signals enabled for 2.4Ghz and 5Ghz so when the set up was happening, it was picking up both WiFi connections from my phone. I disabled the signals from the ATT router, and they still weren’t working, but I wanted to try a third just in case, and it magically connected easily.Since that started working, I wanted to troubleshoot the other two that were still having issues. I figured hat during the setup, the devices remembered the settings so I needed a way to reset them and start fresh. I saw a video from their YouTube account that you can factory reset if you press the button 10 times.Once I did that, both connected easily.I bought 13 of these and never had an issue setting up the other 11 after the network issue / factory reset took place. They are easy to set up and don’t get in the way.Finally I used the extra magnets that came with each device on my fridge, lol.

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 reliablyThe P2 is not worth the time or effort. Aqara’s implementation of Matter is still too immature for a critical-use sensor.

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.

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 fabricationPoints négatifs :❌ Nécessite un hub compatible Matter / Thread❌ Un peu plus cher que les capteurs non MatterConclusion :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.

WICの照明を自動点灯したくなったのですが、反応遅延が大きいとか、WANが死んだら反応しないとかは論外なので、エコシステムにはHomeKit（HomePod mini）を利用し、本センサーでオートメーションを組むことにしました。我が家はもともとPhilipsHue照明を多数導入していましたので、WICにしてはオーバースペックとなりますが、PhilipsHueのホワイトグラデーション75W相当を利用しました。（夜間は色味を変える等も見越して…）ただ導入過程でさまざまな課題にぶち当たります。1. HomeKitに追加できない2. 付属のマグネットの用途がわからない3. 取り付け方の説明が大味4. 電池の絶縁シートが変に挟まってて抜けない5. 電池蓋が固くて手で開けられないまず1つ目、説明書にはペアリングモード（ランプの点滅状態）になってればOKという記載がありますが、うまく繋がりませんでした。これはあえて一度電源オフ（ボタン10秒くらい長押し）して、再起動すると行けました。2つ目、なんか磁石が付いてるんですが用途不明です。説明書にも特に記載がありません。ChatGPTに聞いたところ、本体↔︎アクセサリパーツの距離が規定距離に収まらない時の補助用部品らしいです（ホントかは不明）。なので使いませんでした。3つ目、これも説明書がらみですが、取り付け方の説明書きが大味すぎてよく分かりません。公式サポートに『動画チュートリアル』があるのでこれを一度見ることをお勧めします。とにかく添付の説明書は役に立たない点、ご留意ください。4つ目、まあ偶然のハズレ個体かと思いますが、絶縁シートが電池蓋に巻き込まれてえらい事になってました。幸い絶縁できてた＋シートが抜けたので良かったです。5つ目、絶縁シートを抜く過程で電池蓋を開けるに至ったのですが、マイナスドライバーなどの固くて薄い一の字型の工具がないと開けることが困難です（動画チュートリアルにも力が必要と明言されている）。センサーを貼り付けたあと、電池交換の際には苦労しそうな予感があります。そんなこんなで困難を乗り越えた訳ですが、センサーの質がすこぶる良くって加点が減点を打ち消しました。反応速度、反応精度、電灯のオンオフ切り替えいずれもパーフェクト💯で期待通りのオートメーションが組めました。カプセル型かつ本体サイズが少し大きめで目立つのが惜しいところですが、HomeKit対応ドアセンサーとしては最高峰の商品なんじゃないでしょうか。今後追加で開閉センサーを仕込みたくなったら本品をリピートさせていただくつもりです。（黒色のバリエーション展開もお願いします）
