Aqara Door and Window Sensor P2, Matter over Thread, Requires Thread Border Router, Contact Sensor with Remote Alarm and Local Automation, Supports Apple Home, Google Home, Alexa and SmartThings

This door & window sensor works amazingly well with Home Assistant.I paird this up to my Pi running home assistant via a ZigBee conbee stick & it's yet to let me done.It's a really small sensor so perfect for hiding away on the side of a window or door frame. The double sticky tap on the back makes super quick the install & pairing up to your ZigBee hub is a breeze, it was found instantly on mine. It provides accurate results when opening and closing the door allowing for my automations to run flawlessly.Great value for money!

Just paired perfectly to the Zigbee receiver on my HomeAssistant and works seamlessly via the ZHA integration.

I've bought a few of these now. They connect well via MQTT in home assistant and I've had no issues with them dropping out. In home assistant they show the state including the battery life percentage and the temperature! I've got these set up to turn on and off lights when cupboards are open and closed as well as the loft hatch! No more fiddling around to find the switch or a torch! So far the battery life seems to be great and I don't think I'll need to replace the batteries any time soon!

Quite small and added to Home Assistant via zigbee2mqtt - just permit and push the button

Works well enough with Home Assistant and is a very discreet size & shape. Beware, though, if you have a number of Zigbee repeaters/routers, make sure to pair it when it is next to the router/extender you need it to operate through. It will not move to a better signal if you relocate the sensor.

On a mission to replace all of my Z Wave sensors and controllers in my home assistant installation.On my doors I previously had the sensitive Z wave strips which were extremely slim line and worked very robustly and very consistently. Was a bit worried that these items were going to be a bit too chunky and large when sitting on the exterior of the door, but actually they sit there quite nicely and after a day or two you don't really notice them.Respond extremely quickly actually much quicker than the sensitive Z wave strips.I now have quite a few Aqua components in my home assistant instal and they all work extremely well never had any dramas.Recommended A+

Awesome product, used it to make smart home security system to secure doors and Windows. The zigbee connectivity is perfect. Easy to install and looks elegant.

Aqara promised that an upgrade for the firmware on this sensor would unlock its additional features. This was way back when the sensor first released, and they still advertise that to this day.They said an Aqara M3 hub would be needed in order to get the updated firmware, and access the additional settings and features, leading users to buy the M3 Hub I imagine.The M3 Hub started showing up in December of 2023, and still here we are over a year and a half later without a firmware update for the sensor. Aqara ignores any requests for details on why there's no update.Without the update, the sensor has no configuration options. It can be seen within the Aqara app, and within your preferred Smart Home Ecosystem. This means there's no tamper protection as advertised, and the button on the sensor cannot be configured, so has no function whatsoever.Battery life is good by the looks of it. I've had it over a year and haven't had to replace the battery at all.I can't really recommend these to most people sadly. I feel like Aqara has miss lead consumers with this promise to add the additional functions, but hasn't followed through.
