Xiaomi Human Motion Sensor
Installation via the Homey:
To add this sensor to the Homey log in and go to the device section. Then click on the plus sign and look for the Xiaomi Motion Sensor. If you have not yet installed the APP you have to do this for a while. After this you can start adding it by pushing a pin in the side of the sensor. To keep the sensor awake (and make the addition work) you have to press the hole again every 2 seconds.
The sensor was found neat and the registration of movements comes in. I even have a configuration option to control the "time out". This allows you to set when the sensor transmits "No movement" to the Homey.
You get a motion detector very surprisingly.
