Homekit Switches not working
The HomeKit switches do not seem to work. I have set up the "Capture Image, Night Vision, Restart Cam, Record Video, Horizontal Left, etc" switches in my configuration but they don't seem to work. 

This is my config:


{
                    "cameraName": "Front Entrance Cam",
                    "cameraRTSPStreamUrl": "rtsp://192.168.1.24:8554/unicast",

                        {
                            "name": "Front Entrance Motion",

                        },

                            "type": "captureImage"
                        },
                        {
                            "name": "Restart Front Entrance Camera",
                            "type": "restartSwitch"
                        },
                        {
                            "name": "Motion Tracking Front Entrance Camera",
                            "type": "autoMotionTrackingSwitch"
                        },
                        {
                            "name": "Horizontal Left",
                            "type": "moveCamera",
                            "axis": "horizontal",
                            "direction": "left"
                        },
                        {
                            "name": "Horizontal Right",
                            "type": "moveCamera",
                            "axis": "horizontal",
                            "direction": "right"
                        },
                        {
                            "name": "Vertical Up",
                            "type": "moveCamera",
                            "axis": "vertical",
                            "direction": "up"
                        },
                        {
                            "name": "Vertical Down",
                            "type": "moveCamera",
                            "axis": "vertical",
                            "direction": "down"
                        },
                        {
                            "name": "Recalibrate Motor",
                            "type": "recalibrateSwitch"
                        }
                    ]
}


When I press either of the switches in the home app, the MQTT server does register the request but nothing happens. The below screenshot shows this
