Works quite well so far. However, coverage is sufficient. Furthermore, you can not continue programming as normal on / off times. Keinn "Sun" mode, no automatic. shift of the times, no grouping (absolute flaw!), no direct switching function of all recipients with a click etc. Since I, as seen for more money from other manufacturers much better solutions. Unfortunately, they are not compatible. I open up it is not, as in the 21st century such a device offers such a reduced programming.
