Hi is this config right for mqtt or how does it have to Look. Got. noch reaction when topic Is sent. 


mosquitto_pub -h localhost -t 'siedle/cmnd' -m ring_E_D

  {
            "accessory": "HTTP-SWITCH",
            "name": "Türgong",
            "switchType": "toggle",
            "timeout": 1000,
            "debug": true,
            "onUrl": "http://192.168.0.50:5005/clipall/fury.mp3/5",
               "offUrl": "http://192.168.0.50:5005/clipall/fury.mp3/5",
            "mqtt":{
            "host": "192.168.0.50",
            "subscriptions": [
    {
      "topic": "siedle/cmnd",
      "messagePattern": "ring_E_D",
      "characteristic": "On"
    }
  ]
