Requirements

• I have updated Mushroom to the latest available version
• I did a search to see if there is a similar issue or if a pull request is open.

Is your feature request related to a problem?

No

Describe the solution you'd like

I would like a switch to be restricted, that means you need a PIN to toggle it off.

This is most useful for devices used to power appliances that should never go off if not in a specific scenario or maintenance window.
Thus blocking erroneous toggling would be really nice.
