Hi DLane,
I did fear that I may need to reuse 5 of the zones on the Rachio3-16 zone unit. Or as you suggest, having two Rachio3 systems is another option. I am the second house owner for my property and not fully convinced that we really need 21 zones in our yard in the first place. May be I should take a 2nd look at my current irrigation sprinkler system design and see if I can bring the zones down to 16 or under. It seems a bit clumsy (and expensive) to have two Rachio3’s to solve this 21 zone problem. I can also look at reusing five of the zones or take a look at Smart Hunter sprinkler solutions as well. Appreciate your advice. Thx
