Adding Xiaomi Door and Window Sensors to SmartThings

One of the initial reasons I chose to invest in SmartThings was the ability to keep an eye on my house via my phone, making sure it was secure. The initial starter box included 1 door and window sensor and 1 motion sensor. These were positioned in the most effective places protecting the front and back doors.

However, this did not cover all doors and parts of my house were still accessible without triggering SmartThings. This made me a little worried, especially with a newborn child.

The problem with SmartThings sensors is the expense. Each additional sensor was coming out at around £30 (this was until a recent price drop on the 6th December to £20.99). I had 4 doors which I needed to secure which at the time was looking at £120 (now £84).

I needed a cheaper solution!

Through research and a couple of posts on the facebook SmartThings user group, I discovered the Xiaomi door and window sensors. At £6.11 per sensor, it seemed like the ideal solution to add to my smart home. In total for 4 sensors with delivery and customs protection, it came to £31.40 (working out at £7.85 each). The initial delivery said 3-5 working days, it turned out to be 15 days before their arrival.

How to connect Xiaomi Door and Window Sensors to SmartThings

Creating a Device Handler

The first step to adding the door sensors was to add a custom device handler to the SmartThings control hub. This allows us to recognise the devices when adding them to the SmartThings app. To do this login to your control panel at and go to my device handlers at the top menu.

Click the ‘+ Create New Device Handler’, select the tab ‘From Code’, copy code from and paste in the box. At the bottom underneath the code click ‘create’ and then back at the top click ‘publish’.

Once you’ve added the custom code. The next step is to add the devices to SmartThings. To do this go on to your SmartThings app, got to my home and click the + button in the top right corner. The app will immediately start looking for new devices. Now on your sensors, there is a small hole at the bottom, you’ll need something small like a pin to press it (I used an earring). There is no pattern (unless someone has found one), you simply need to alternate between clicking the button and holding it.

XIAOMI Door and window Sensors Afterthoughts

The Xiaomi door and window sensors proved a useful addition to my smart home at a fantastic price. Although they’re not as easy to connect or as feature-packed (such as temperature readings) as the SmartThings sensors they prove to be reliable and work extremely well.

One of the sensors did drop out after 12 hours (the first time I added it), however, after reinstalling it, there has been no further issues.
