@robertokc that would be a great product. I'm on the Board of my HOA (1158 single family homes), and we have over 30 different controllers for our Common and Recreation areas. Unfortunately, we also have a mix of wired and battery powered controllers, due to remote locations.
Just a commercial unit with the features you mentioned would be fine. I think that web / mobile access without an included screen would be fine. Everybody has a smart phone today, especially the supervisor of a landscaping team.
Our $40,000 annual water budget could be much better spent by properly watering with a commercial Rachio device, plus our extensive landscaping would be in much better condition.
I will say this: commercial and public (park) facilities have very generic watering setups. We have pop up sprinklers in most places that are performing double duty watering grass, plus the trees planted within the grass strips. Programming zones is going to be tricky in these circumstances.
