It seems that Rachio's notification system does some odd rounding and does not discriminate past a minute interval. As such, my zones are now reporting as having run for 0 minutes, and my seasonal adjustments report similarly strange numerals. It should not be too hard to convert to a messaging system that is capable of saying that your drip line has been adjusted to run from 1 minute to 55 seconds, rather than from 1 minute to 0 minutes. It's quite confusing to see reports of zones running for 0 minutes since I don't know if it really didn't run, or if it just ran for less than a minute.
This suggestion is for both the iPhone app push notifications and email notifications.
