Alarm Panel
I have a Honeywell Lyric Alarm Panel that is integrated with SmartThings via an SmartApp... the panel is exposed in this app as both a lock and a switch so that it can be either Armed Stay or Armed Away, depending if the lock or switch is used  Disarm is off on either one. 

Looks like when this is added to home bridge, it doesn't understand the switch, but the lock works just fine:

If you need any other information, please let me know!  Thanks!
