Works to control several radio outlets on two floors so far without any problems, the accuracy of the clock is ok Functionality can but something to be desired: There is for example no programming for weekdays, no automatic adjustment of the switching times of sunrise / sunset and not the possibility of applying a switching program at several outlets. Will I eg three sockets at 7:00 on, I need to create three switching programs. Will I change the switching time at 8:00, I have to adapt to all three switching programs. While I can combine multiple outlets on a code, but they are always connected together, even with manual shifting. Conclusion: For simple applications, it was good, for more sophisticated programming but unsuitable.
