Should be 6 digit pin enter option when switch on

should option to enter pin for on any switch. Ex - 6 node my device cover hall or outside light and one emergency siren.
So I want to on emergency siren when enter 6 digit pin code.

We have pin feature in Lock controllers but not in nodes
Other than that nobody is asking for this feature. If a feature is not used by most of our users, its not worth the effort to build.

You will be implement this feature definitely in future.
