This is a fake relay which do not physically connect to anywhere, does not actually do anything. It just acts like a relay, remembers the latest command, updates the interface.
- It may be used to fake any relay, like the heating control output of our thermostat driver.
- It may be stored in a hidden room and used like a variable for programming.
- Again in a hidden room, it may be used as a status feedback for our Magic Buttons system.
- A free driver
