@Dan8 All good suggestions, I'll try to answer your questions.
At this time we don't have plans to add more zones. We do allow multiple devices to be managed on the same account.
We support running 2 zones (from a power perspective).
Yes, the master valve feature is for the irrigation master pump. Currently, all the zones are programmed to use or not use the master valve. We do have plans to individualize them (one or more zones for master) but I can't give you a date but it is in our software backlog.
Yes, you can enable/disable all/any of the smart watering features which rely on weather data.
We support a large number of programs, probably close to 12. It depends on the size of the programs.
The software doesn't allow you to run 2 zones at the same time. We do have plans to allow for this mix/match but I don't know when we will implement that feature. It is in our software backlog.
I hope this answered everything. Please let us know if you have any other questions or feedback.
Have a great day!
