I have only one EZFlora right now. I understand that if I get another one, I can control more zones. Is this compatible with the pump function in zone 8 as well? Would the pump be controlled by zone 8 in both devices or only one? IOW would using 2 EZFloras with a pump give me 15 valves or only 14?
Each EZFlora is independent. EZFlora number 1 knows nothing about EZFlora number 2. Unless being driven by some Home Automation device/product that would control both EZFlora devices, you have 7 zones and 1 pump control in each EZFlora.
