My timers turned items on an hour early today. This is the first time I noticed after an upgrade mid week. I turned off the items and they later came on at the correct time. Timer set to Sunset plus :30. This appears an extra firing.
To make sure I understand, you upgraded mid week, and the timer in question has been working fine for a few days, and then Sun it triggered incorrectly, or is this timer only set for Sunday?
Can you confirm the time on the EZSrve is correct, and that the Sunrise / Sunset times are correct as well?
