Just cloned an existing rule that worked fine, turning dimmers and switches on/off in a fish room/house
I basically added a few additional else If's threw in a few delayed on/off's and changed/added a few extra time triggers, checked and nothing showed up in logs to show it was working, also the "run actions" and "update rule" buttons were missing, as there wasn't anything in the logs I changed a setting, clicked "done" (no update or run action buttons) and finally got a mention in the logs which was the following
