Very easy to use, yet very powerful. Excellent, fast support by the developer. I don't know how he has time to respond in such detail so fast each time I have a question, but it sure has helped a newbie to home automation set up a rathe complex system very quickly. Great program, great developer. What more could you ask for in software. $90 is a lot for something that is included for Windows when you buy a controller, but he earned every penny from me. Bundle it with EvoCam with its Quicktime and unlimited camera support, and it outshines any Windows solution. Suggested next step, ability to send wireless commands from the CM15A.
