Just in case anyone looks at this and has the same issues, I replaced the Hunter relay with the Orbit relay (less than $40 at Lowe’s), and so far, I have not had any pump faults in the couple days since I swapped them out.
I never did hear back again from Orbit support, so I guess they really do not care about following up with customers having issues.
I get the same message from my iPhone when I try to upgrade the firmware. It is very annoying. No idea why firmware upgrade is not an option from the website access.
I have my B-Hyve connected to my Orbi mesh network and have had no problems with the connection.
