After a power outage - if it was ON before the outage - it does not return to the state it was in and does not connect to the wireless network to bring it back to the ON state. Three times it has caused the same damage to me. I have tried to set a daily routine (ON at 08:00), so that it will return - at least - on its own after a power outage the next morning. Although I had tested it at home, when I had to leave for a while and there was a long power outage, it never returned. Obviously, the internal memory battery ran out and it had no way of knowing what time it was.
