/**
 * Users can add on-off switches. A on-off switch can turn on (or off) lights.
 * If a light has an intensity level, when it gets switched back on, it gets the last available
 * intensity level that was set by the user (or 100% if no such level exists).
 * The user can change the state of a switch through the SmartHut interface.
