The advantage compared to the old model, which was connected by means of a magnet to be glued by a reed relay is, of course, that this is omitted. Instead, for example, must cover the viewing window on a sensor window sash when closed. This works acc. To instructions up to a distance of 3mm. In practice, I was able to realize a somewhat greater distance in not fully cover the window and still switch reliably. But this may vary from device to device. The integration into the control software was not a problem. A further advantage is the low cost Micro Battery, which replaces the two button cells of the mechanical model. Unfortunately, this results in a disadvantage: The device has fallen quite long.
Overall, outweigh the benefits of the new development for me, although the disadvantages, but a motivation for the exchange of all predecessors, I do not see. Because the most important functions are available in both versions.
