Well, that explains it then. Most z-wave locks don’t seem to have door sensors. Usually that status sensor, latch sensor, handle, etc. always reports open. You’re the first I’ve seen report it as doing anything, hence my initial response. Sorry, I should have asked.

Can you go back to 6.7.0 and re-interview the device and watch the driver debug logs in z2m? The logs will tell you if the device is accurately reporting whether it supports the door status or not. If it’s saying the wrong thing, it could be an explanation. This is new functionality added in V9 of the driver.
