I called orbit, they said the rain bird sensor is not compatible and will not work with b-hyve. I’m assuming based on your findings (Randall and Tim) this is not the case. Maybe using the orbit sensor allows for the updated calendar info in the app? i don’t want to purchase a new sensor but think ill try both methods and see what happens. Im in SoCal, so i don’t get a lot of rain but it would be nice to have the system fully operational. Thanks for the info, this was the only answer i could find on the topic.
