I have used X-10 to turn my holiday lights on and off for years mainly because we have so many lights. We put on a good show for Halloween and right after I start putting up 27,000 Christmas lights. I have been increasing the complexity of our display every year with some animations and flashing lights but it is vary difficult and time consuming using Activehome and the X-10 hardware. I would like to take it to the next level this year but can not find any good X-10 software to use. I have been looking at the software offerings and am having a hard time finding something to help me to the next level. I have looked at allot of the free stuff and found most can not be programmed faster than 1 sec. not fast enough for sequencing dancing lights and still time consuming to program. Looking at allot of the paid programs I can not determine if it will help without buying them all. I am looking for a X-10 control program that is easy to program sequences down to a tenth of a second to do some dancing lights in my 45 foot charismas tree this year. Can anybody tell me if the software they are using mite be able to help or should I scrap the hole idea and us some thing like Weed Techs digital I/O board and hope to find some good control software for it to do dancing lights. The ultimate for me would be a program that would run off an excel spread sheet where if a box is filled to would turn on an output and stay on if more boxes where filled and then off at the next clear box running over time. I have seen all the ready made charismas light hardware and software but I do not have the time or money to go that route and was hoping to save some of my investment in X-10 that has served me well all these years leading up to this point.
