{
                pin: 24,
                name: "power",
                longPress: {
                    title: "Power off",
                    message: "Keep pressed for 3 seconds to shut down",
                    imageFA: "power-off",
                    notification: "DOOR_STATE",
                    payload: "close.png"
                },
                shortPress: undefined
            }

you would therefore need a button released to send open.png
