well, I am on computer controle now for my lights. I had a bit of problem setting up the program to run it so I fired off a e-mail to the author (Bill-e) and 10 min later he came back with the solution.. my fault I for got to copy a file to tell it how to use the ports hehe.
anyways it all looks good now, it has the capability of controling 6 lights + a moon light.
you can set it up to mimic the sunrise and sunset from any place in the world and it varies the moonlight bulbs acording to the moon phase.
The wave maker page can controle up to 6 pumps and has functions to go random or to vary on/off times to simulate tides, intensity feeding quite time ect.. and you can set # one to turn on/off at a constant interval for use in a directional flow changer.
now none of thease idems that it controles has to be a light or a pump.. if you only want to run a skimmer 12 hours a day you could do that or anything else that is powered.. as all the program does is turn on/off a X-10 modual.
if you want to see the menues you can go
HERE and take a look at the screen shots.
