When converting a Basic Rule to RM5 I noticed that the last action that turns off a switch gets converted to turning the switch on instead of off. It's an easy thing to miss. I noticed it because I converted a few rules and my lights never went off. I manually fixed them, but the bug should be addressed, unless it is unique to my setup. I'm on 2.5.0.159
[EDIT] I'm updating my hub now to 2.5.1.142 to see if it was fixed already
