Correct, the rules (should) work as in OH1. I have seen them working on my system.
However, as of some weeks ago, on the chnage to a new nigthly I have been observing the above mentioned problems with rules. I even did a complete reinstall of my RaspBerry2 (including OS and OH2).
Maybe @martindk is observing the problem I have. In my case I believe the problem to be myself, however I can’t figure out what I’m doing wrong.
