Hello, I think I got it fixed by routing my sprinkler controller through an Netgear Extender instead of the main Netgear Orbi router.  If you are googling Netgear Orbi vs Doorbell Rings, there is a well known issue with doorbell rings vs Netgear Orbi connection which i think its the same problem in this case.

You won't be able to connect if its offline

I'm not sure I understood your question clearly but I thought there is a 'soil type', shade, 'sprinkler head' types for each zone.  You just need to set the same setting for each zone and the watering will come out the same right?
