Good product, Spartan documentation, suitable for frames with paragraph

This sensor is for especially for assemblies suitable in which the to be monitored object (door, window) relative to the frame on which you mounted the sensor, forming a shoulder. For windows that connect area (eg double windows with narrow web between the halves of the window, this product is not or only conditionally suitable, since the optical sensor is located on the side of the device and therefore in geschlossenenem state must be relative to the frame. For double windows more appropriate, in my view, the magnetic sensor, since one magnet and the sensor can be mounted facing each other there.

The product fulfills resume its purpose, even in a light brown wooden door the attached reflective foil is not necessary to increase the reflection, the contact detects the Öfnnen and closing even as perfect.

If you just want verbinen with other HomeMatic products, the device is certainly create with the accompanying documentation. It becomes more difficult when you want to use this sensor with software support to a larger group of devices. The HomeMatic documentation in this regard is very spartan. In this case, I can only advise you to thoroughly research on the internet. Many have these sensors successfully in home automation projects in use and plenty written about it, so I could integrate the sensor with success in my "FHEM" Umgeung after a little research.
