Gen 3, 16 Zone w/ wireless Flowmeter, want to add wired FM

[GreenLeaf]

Hi-
thanks for your response. I found this thread and so now I’m a little confused:

How many flow meters do I need? Can you have more than one or not?

How many flow meters do I need? You will need one flow meter for every backflow preventer in your system. If you have more than one controller and only one backflow preventer, your system will not be compatible, as Rachio only supports one flow meter per Rachio 3 Smart Sprinkler Controller. So I can only have one flow meter? The front and back yard have their own water source. So I would need two.

maybe @franz can clarify/assist?

Thanks, Dave
