mikk; You are using Active Home Pro that was updated to work with a CM11A or the original Active Home that was originally supplied with a CM11A?
I don't know if AHP was ever tweaked enough to do downloads to the CM11A.
I always got a out of memory error. No matter how small I made the Sunrise Sunset tables.
The old Active Home was able to download the timers just fine for me also.
Also if you unplug the CM11A. It has no battery backed clock and forgets the time. Then it starts sending the computer a set the clock request.
