Zigbee Door and Window Sensor 3 Pack, Wireless Mini Contact Sensor, Home Automation, Requires Aqara Hub, Zigbee Connection, Kid Safety, Compatible with Apple HomeKit, Alexa, Works with IFTTT

I have an August lock that is supposed to provide some "door ajar" alerts. It never does, and the sensor does not integrate well with HomeKit. Recently, I put down a door mat that catches on my door and leaves it open, and I've had a few times where I've left the house and left my door wide open because I'm used to it closing behind me. I already have a few Aqara sensors around my house for leak detection, and a door sensor on a deck door that is harder to close and can get left ajar accidentally, so I decided to get another sensor for my front door. This sensor is perfect! It was easy to setup and get connected to my existing Aqara hub, and it works very well with HomeKit. I get notifications every time the door is open or closed, and in addition, priority alerts when the door is left open past my timeout setting (two minutes). Installing it was also a breeze, and one of the sensor parts is small enough that it fits on my recessed doorframe with just enough distance between the sensors for it to be effective detecting opening and closing. My Zigbee hub is close by, so it does not need to communicate over a long distance, which should probably help with battery life - however, the sensor on my other door is on a second floor and it communicates perfectly, and I have only had to replace its battery twice. I continue to be pleased with the Aqara ecosystem!

I was pleasantly surprised by how effortless the setup was—just pair it with your Zigbee hub, and you're done. No complicated steps, no fuss. It connected instantly and has been working flawlessly ever since. The responsiveness is great, and it integrates smoothly with my smart home routines. If you're looking for a reliable sensor that "just works," this is it.

works very well, and very compact size

I bought these because they're incredibly tiny and Aqara has a good reputation for seamless integrations with Home Assistant. (I don't use an Aqara hub or Alexa.) Pros: - They're very unintrusive. Being so small and rounded, you hardly even notice them. - Native Zigbee, so super low power and no proprietary hub needed. - Battery life, at least so far, has been decent: reporting about 65% after six months of use. Cons: - They were harder to connect than other Zigbee devices, requiring me to bring them very close to a relay or, if I'd already attached them to the door, plugging in a Zigbee outlet nearby temporarily. - They tend to disconnect slightly more often than other Zigbee devices, even in areas with very strong mesh coverage. Ultimately, I decided to go with Sonoff instead for the rest of alarmed doors. They're quite a bit larger, and the boxy shape catches the eye more, but they're much more reliable. And for something connected to my home security system, reliability is king. For interior doors that don't matter so much, I prefer these for their small size. They're great for non-critical automations like turning on the bathroom fan when the door closes, or adjusting thermostats depending on which doors are open.

Connectivity/Pairing: I connected these to HomeAssistant using a Sonoff Zigbee dongle. Getting the devices to go into pairing mode is very confusing if you don't read the directions. You have to press the button for exactly 3 seconds - no more, no less, otherwise it'll go into a different mode. Otherwise, pairing them was fine, and they work great with HomeAssistant. Accuracy: These are very accurate. If I look at my phone while opening and closing the door, the sensor sends updates in real time (less than 1/2 second delay). I have not noticed any false positives or negatives. Adhesive strength: If you stick these on properly, they stay on very tightly. It took a hair dryer and a lot of effort to remove one. Surprisingly, removing it didn't damage the painted doorframe, but I wouldn't expect that to always be the case. The adhesive is quite strong, probably strong enough to rip paint off in the right conditions.
