First thing I noticed is that under the default settings, any DSC zone added as default "Security" device type will become a DSC keypad, which is not what one wants and it causes a KeyError in the plugin.
I seem to be able to override this by selecting "Show all options" and then selecting e.g. contact sensor or occupancy sensor as device type. Contact sensor devices can then later be changed to window or door in the Home app. So this seems to work nicely. But, when open a zone, Home app does not show the zone as open. What is wrong here? I did not select anything under Device State in the setup since I got an error message with what I thought should be selected:
ContactSensorState: value=closed is not a numeric value.
