-t --on           turn the relay on
-f --off          turn the relay off
-g --gpio=gpio    the gpio the relay is connected to

        "living": {
                "name": "Living",
                "switch": {
                        "name": "switch",
                        "protocol": [ "relay" ],

			}],
                        "state": "off"
