I'm having same exact issue as several others reported here but there was no resolution and the thread was closed https://community.ring.com/t/retrofit-kit-showing-empty-zone-as-open/29480 I have 6 zones only and it's been like that for years. Now Zone 7 says it's Open and ready to test. There is nothing connected to it and never was. There's no way to disable it in settings. Is this a firmware or hardware issue? My family members also have retrofit kit at their house so I checked theirs and same issue! They have 5 zones connected and Zone 6 says it's Open and ready to test
