* Set lock status correctly for Schlage BE469 Z-Wave locks
PR #17386 attempted to improve the state of z-wave lock tracking for
some problematic models. However, it operated under a flawed
assumptions. Namely, that we can always trust `self.values` to have
fresh data, and that the Schlage BE469 sends alarm reports after every
lock event. We can't trust `self.values`, and the Schlage is very
broken. :)
When we receive a notification from the driver about a state change,
we call `update_properties` - but we can (and do!) have _stale_
properties left over from previous updates. #17386 really works best
if you start from a clean slate each time. However, `update_properties`
is called on every value update, and we don't get a reason why.
Moreover, values that weren't just refreshed are not removed. So blindly
looking at something like `self.values.access_control` when deciding to
apply a workaround is not going to always be correct - it may or may not
be, depending on what happened in the past.
For the sad case of the BE469, here are the Z-Wave events that happen
under various circumstances:
RF Lock / Unlock:
- Send: door lock command set
- Receive: door lock report
- Send: door lock command get
- Receive: door lock report
Manual lock / Unlock:
- Receive: alarm
- Send: door lock command get
- Receive: door lock report
Keypad lock / Unlock:
- Receive: alarm
- Send: door lock command get
- Receive: door lock report
Thus, this PR introduces yet another work around - we track the current
and last z-wave command that the driver saw, and make assumptions based
on the sequence of events. This seems to be the most reliable way to go
- simply asking the driver to refresh various states doesn't clear out
alarms the way you would expect; this model doesn't support the access
control logging commands; and trying to manually clear out alarm state
when calling RF lock/unlock was tricky.
The lock state, when the z-wave network restarts, may look out of sync
for a few minutes. However, after the full network restart is complete,
everything looks good in my testing.
