Got my Iro installed and working a couple weeks ago - so far, so good.
One suggestion for something I'd like to see, would be a way to group multiple watering times together into, for lack of a better term, a schedule. Then provide the ability to enable/disable watering on a per schedule (consisting of multiple watering times) basis.
This would provide the ability to create schedules for different times of the year - e.g. summer, winter, grass seeding, etc - without having to adjust/enable/disable multiple watering times.
Additionally, would be nice to get a FAQ up for the 'Water Budgeting' feature, similar to the one for 'Weather Intelligence' to get an idea on how it works.
