Great Idea. Unfortunately, the part goes rechnt broken quickly, is to read as well as in other reviews. I have 3 of them in action! Internally, a latching relay is installed, which falls at shutdown and so really comes down to zero power consumption. Brilliant! Unfortunately, the latching relay is obviously of poor quality so that it more and more firmly welded sticks after a few months of use, ie do not switch off! This happens now in all three doses I have in use, unfortunately. Ansmann please make improvements! So it goes unfortunately only one star!
