Hi all, I have been testing my program for a couple of days now and it seemed to work fine until I introduced a power outage to it. It is a reef controller that has time, temp, lighting, heat control, moon lighting, and 2 relays. The time, temp, relays, and heat are not affected by power outages. The moon lighting, and lighting are only affected by power outages after midnight. I lose the on-off display and also lose power. I have tried resetting the display and on the board. Once the clock reaches the photo period it works fine until a power outage after midnight. I will post the code.
