I've got a rule set up to notify my phone when triggered by Sunrise, and another for Sunset, and I only sometimes get the message, most often I don't get any message. (my mistake, this is working)
Also, I have sunset-to-sunrise predicates in some of my rules and they work, but are severely delayed, often by 12 hours or more. I have noticed that for rules that aren't triggering when they should, I can see red text in the Apps page which says the predicate is false. If I go into the rule, it will say the predicate is true, but will still not trigger, and will still say "predicate false" on the Apps page. If I go into the rule and press Done a few times then the red text on the Apps page disappears and the rule will trigger correctly.
I'm on version 126.96.36.199, which is the latest at the time of this post.
My timezone is +10.
I've checked System Events->Location Events and the events and times look good.
Also had this problem in previous version of RM.
