First off, I absolutely love the iOS app. Can’t say enough good things about it. (I am on the 2.0 beta).
I know there is a 150 push notification-per-day limit. Although I doubt I will hit that limit ever it would be nice to keep track of where I am at any given time. Would it be possible somehow to create a sensor that tells me how many messages I have received (or, maybe better, how many I have left before I hit the limit?)
Also - any news on when 2.0 will be “stable” and released through the regular channels?
I would create the counter and let it ride and never reset it, then use the History Statistics sensor to calculate things like the number of times you were notified today, this week, this month, this year, etc. I do this with TV time, and I track my hours at the office, at home, and at all of the other zones. You could also incorporate a cost measurement with an input_text sensor to determine things like cost/hr of TV viewed, etc. Go crazy.
