I've installed and programmed, reset, and programmed again this device. It appears to work fine for a minute or two, then the lights start blinking. I've programmed it for ON at sunset and OFF at sunrise. However, P01 on and P01 off soon start flashing alternately, and it's almost as it the OFF program were set to the current time. Ie, it's after sunset and the lights should be on, but then P01 OFF flashes in the screen with the current time.
