Using a scene we have the ability to reverse the status of a device (turn it off if on or on if off).
I would want to request this same ability for a scene. Currently we can use a scene to turn a other scene on or off, but not to reverse it’s status.
A use case for this would be if I want to override a motion sensor with a button press and later use that same button press to disable the override. Using a light switch with 1 more button than your number of lights is a perfect option since you don’t need to connect the extra button to a light, you can just use it as a scene controller.
Without the reverse action I would need 2 different scenes, one for enabling and one for disabling and this won’t be possible in the above scenario since you would need 2 buttons for this.
