I hope someone can help. I programmed six lights to come on using the dusk feature (not using a macro). Outdoor lights on at dusk, foyer light on 40 minutes before dusk, dining room light on 35 minutes before dusk, bedroom light on 30 minutes before dusk, etc. Off times are specific e.g., outdoor lights off at 11:30 pm; foyer off at 10:30 pm; dining room off at 10:20 pm; bedroom off at 10:15 pm. Dusk is set to my locality, repeat is checked and everything is downloaded to my CM15A, which is plugged in to computer's USB and an electric outlet and has fresh batteries installed. I'm using version 3.306 version updated 2/14/2011. This works perfectly for several days, then unexpectedly, after the lights came on and went off as desired, they come on again, only this time it is in the middle of the night (unwanted), which wakes me up, etc. This is the second time that that sequence has happened. This is in a second home. In my other home, I have used X10 successfully to turn lights on and off. The only difference is I don't use the dusk feature in my other home, where the on times are set to specific times. I would really like to get the dusk feature working properly, without these midnight surprises. Thank you.
