I have seven HS200 switches, and most of them work properly. However, two of them are difficult to toggle manually. When I press the switch, it will quickly turn on and then immediately off as I lift my finger.
I suspect that I'm not the only user who is experiencing this problem, so my suggestion is to add a setting for debounce in a firmware update. This would enable users to set a period of time after the switch is physically pressed before it will register a second press, and eliminate the on-off behaviour.
This could also be accomplished by adding the double-press setting available in the HS200, with an option to ignore the double-press so that it doesn't toggle the switch twice.
