Xiaomi Door & Windows Sensors – Guide to Use

Xiaomi Door & Windows Sensors – Guide to Use

Anyone who follows our site regularly will know that since the release of the HomeKit-enabled Aqara gateway last August, we’ve steadily featured both Aqara and Mijia products as soon as they become compatible. This however also led to some confusion over which products were Aqara and which were Mijia, in addition to the blurred lines as to where the name ‘Xiaomi’ all fitted into the scheme of things.

So, today we will talk about brand-new Xiaomi Door & Windows Sensors which are really worth it and moreover, you can already buy it in our Shop here: Xiaomi Door & Window Sensor

The internal part of the box is solid due to having a strong boundary around the edge to keep things from being crushed, and cutouts to hold the sensor and magnet in place. This is only a door sensor, so there’s not a lot in terms of content, so along with the two parts of the contact sensor, you get the manual in Traditional Chinese, and spare double sided stickers for both the parts of the contact sensor.

The casings for the sensor and magnet both use a form of matt plastic. The matt finish is quite nice, especially if you’re sick of seeing shiny white plastic everywhere you turn in your smart home. It’s a minor detail, but it’s all about the small details for me. Both parts of the sensor already come with double-sided adhesive stickers already attached, so if you screw up the initial placement, or simply want to relocate the sensor at a later date, then do keep these spares in a handy place, as they’re cut to just the right size and shape. You can use standard 3M-style double-sided stickers of course, but they usually tend to be thicker, so they would make these sensors appear slightly raised if you don’t use the original stickers, which are quite thin. The front of the sensor has the Mijia logo, that appears on many of their other devices, along with a small hole through which a small blue LED lights up when the status of the device changes, or flashes during initial setup. The sides of each part have a small horizontal line that you’re advised to make sure line up with each other when affixing the two parts to a door or window, to ensure they work at full efficiency.

The only other difference between the Aqara and Mi sensors is the way in which you reset them/prepare them for installation; The Aqara sensor, like the Aqara motion sensor, has a small button that you press, whereas, as seen in the image above, the Mi door sensor has a pinhole that you insert a paperclip or ‘sim pin’ into in order to perform a reset. This is also the case with the Mi motion sensor, which we’ll be reviewing in due course.

Below the reset pinhole, is a small inset groove to allow for the opening of the sensor, which in turn allows you access to the battery section. The sensor takes a small CR1632 battery, which while quite easy to find, isn’t as ubiquitous as the CR2032. The battery should easily last a year, and so far, the battery on another of these sensors is into its 18th month. This is partly due to the protocol that this sensor uses, which is ZigBee, and also why you will need a hub for this to work. If you aren’t using HomeKit, then the Mi Gateway will work fine, but for HomeKit integration, you’ll need to use the Aqara hub.

As this is a Mi Home compatible device, first and foremost, you will need to add it to the Mi Home app initially. There are two ways to do this, and essentially they should both work exactly the same, but I’ve found the standard way, which begins with clicking on the ‘+’ sign in the top left corner of the Mi Home app home screen, doesn’t always result in the sensor then being exposed to HomeKit. the method I tend to use is just as easy and seems to work to get the sensor exposed to HomeKit every time.

Home Screen of Mi Home app – select your hub, then the ‘Device’ tab
Click on the hub at the top of the list
Select ‘Add child device’
  • Open the Mi Home app, and select the hub that you’ll connect the sensor to
  • Select the ‘device’ tab, then click on the hub at the top of the list
  • Select ‘Add child device’
Select the device you’re adding – the Mi Window & Door Sensor in this instance
Reset the device by inserting a sim pin into the hole
  • Select the device you want to add from the grid of devices;
  • Reset the device by inserting a sim pin/paper clip into the hole at the base of the sensor until the blue light flashes 3 times (usually around 3-5 seconds). You have 30 seconds to complete this section.
Select the appropriate room for the sensor
choose a name
you’re done – click next
  • Once the device has been installed, the Aqara hub will let you know it has been successful, and you can go ahead and add the device to the correct room;
  • Name the sensor as you see fit;
  • Then click ‘Next’ to complete the procedure.

  • Switch over to the Apple Home app, and your new sensor will appear at the bottom of the screen.

If you’ve already been using any of the Mi or Aqara sensors, you’ll be aware of how reliable they are and how fast they are to respond. With regards to the door sensors, the Aqara and Mi both perform excellently well.
