Since RM 4.0 is a change in how to build rules, I thought I would start a threat so we could help each other make our rules better. Here's one to start.
I have a rule which turns some lights on when it's overcast or when it's evening. I also don't want it to run until after 9:00 in the morning. It runs as it should and that's great. When I first created it, my logs would get a lot of entries since the rule would fire even though the lights were already on. Following one of Bruce's example's, I included the Private Boolean so it wouldn't continue to run when it was already true. This worked and it didn't fire after it became true.
The glitch is that while it's false, it's filling up the logs. Any ideas how to slow that down?
