@vv132, feedback on your questions below:
Sure are! Once you have an Iro, please keep an eye out here for notices for beta testers
Not at this time, but we're always looking for feedback on improvements we could make to the Iro. Perhaps you could PM me your recommendations and/or requirements? We might be able to think of some workarounds.
Yep, sure will!
Maybe. It's hard to see without having a photo of your wiring to review. Perhaps you could post one here for others to see and learn from?
Could you provide more details about the 2 zones and why they have to be connected? The Iro's pump valve runs for all zones -- it cannot by deactivated on a zone by zone basis.
No, sorry, the Iro doesn't track flow or GPS. Sorry.
Hope this helps, let me know if you have any other questions we can help answer.
