After some initial problems all my timers, including the ones triggered from Sunset, have been running fine until this past Wednesday. We had a very short duration power outage Wednesday morning (less than 10 seconds) whcih seems to have totally confused the EZServe. I had lights going on and off at apparently random times and timers not firing at all. I looked at the status of the EZServe and the Sunrise/Sunset times did not make sense. Based on the strange Sunrise/Sunset times I RESET the EZServe and re-established the time zone. Everything seems to be running fine now. I would expect the microprocessor to be tolerant of a power outage like that. Any thoughts?
