I have been using the smarthome Power linc Controller 1132CU and the Smarthome manager essential software. I love this product. In March I tried out the CM15A for a month and it was so unreliable that I asked for a money refund. The Smarthome unit has been working exactly the way I programmed it
The Smarthome essential software is not as flashy as the AHP software and if you would want to program a light for a specific date you will need the Manager essential plus software for around $115 with the Powerlinc controller or $69.00 for just the software. The big difference with Smarthome and the CM15A is that the smarthome is a much more reliable system.
I would highly recommend the Smarthome software if you are having the same problems that I was having with the CM15A unit. Mainly making lights to go on or off.
