I use the SMART-box to my showcase lighting and currently controlling the Christmas lights. It is great that you can program the hours after astronomical times, eg switch on 1h before sunset and off 2h after sunrise. Also accessible through the iPhone with the FRITZ! App works for me perfectly, the box can be thus connected remotely and even measures nor the room temperature! Here can be (so far) with FRITZ! Smart Home control no radiator valves, that would be desirable!
