[MMM-MQTTbridge] A module to publish and receive MQTT messages

Cr4z33

@wishmaster270 I would like to intercept the MQTT event of when my Dahua video doorbell is pressed and send the stream to MMM-RTSPStream, but I don’t really know how to get the two modules to “talk” to each other… 😅

So looking at DahuaVTO2MQTT registry this comes out when the doorbell button is pressed:

MQTT message published, Topic: DahuaVTO/VideoTalkLog/Event, Payload: {"Action":"Pulse","Data":{"EndState":"Missed","LocalNumber":"9901","LocaleTime":"2024-07-22 10:09:27","RealUTC":1721635767,"TalkTime":0,"UTC":1721639367}}

Now looking at MMM-RTSPStream readme this is the section where it explains how to control it from other modules (aka MMM-MQTTbridge), but as I said above it didn’t make sense to me.

Can you please help me (at least on your module’s side)?

@Cr4z33 Hi, you will first need the URL of the RTSP stream of your camera.
In the next step you will need to subscribe to the topic in the file mqttDictionary.js

var mqttHook = [
    {
      mqttTopic: "DahuaVTO/VideoTalkLog/Event",
      mqttPayload: [
        {
           jsonpath: "Action", 
           conditions: [
                       {
                         type: "eq",
                         value: "Pulse"
                       },
                     ],
          mqttNotiCmd: ["doorbell"]
        },
      ],
    },
  ];
var mqttNotiCommands = [
    {
      commandId: "doorbell",
      notiID: "RTSP-PLAY",
      notiPayload: "YOUR-STREAM-URL" 
    },
  ];

But you will need to find a way to stop the stream in any way.

@wishmaster270 thank you mate!

Yeah I will add a timeout command as I don’t think it will take much to search for it. 🙂

@wishmaster270 sorry to bother you again.

Right now my mqtt Dictionary.js looks like this

var mqttHook = [
  {
    mqttTopic: "zigbee2mqtt/BTicino F20T60A",
    mqttPayload: [
      {
        payloadValue: "",
        mqttNotiCmd: ["POWERMETER"],
        mqttPayload: ""
      },
    ],
  },
];

var mqttNotiCommands = [
  {
    commandId: "POWERMETER",
    notiID: "POWERMETER_VALUES",
  },
];

module.exports = { mqttHook,  mqttNotiCommands};

so how should I add the new piece of code please?

wishmaster270

@Cr4z33 The two datatstructures are arrays containing objects. So you can simply append the two objects…

var mqttHook = [
  {
    mqttTopic: "zigbee2mqtt/BTicino F20T60A",
    mqttPayload: [
      {
        payloadValue: "",
        mqttNotiCmd: ["POWERMETER"],
        mqttPayload: ""
      },
    ],
  },
  {
      mqttTopic: "DahuaVTO/VideoTalkLog/Event",
      mqttPayload: [
        {
           jsonpath: "Action", 
           conditions: [
                       {
                         type: "eq",
                         value: "Pulse"
                       },
                     ],
          mqttNotiCmd: ["doorbell"]
        },
      ],
    },
];

var mqttNotiCommands = [
  {
    commandId: "POWERMETER",
    notiID: "POWERMETER_VALUES",
  },
  {
      commandId: "doorbell",
      notiID: "RTSP-PLAY",
      notiPayload: "YOUR-STREAM-URL" 
    },
];

module.exports = { mqttHook,  mqttNotiCommands};

@wishmaster270 thank you again!

However nothing happens in the MagicMirror frontend (although I can see the MQTT event if running MM by npm start

[23.07.2024 17:15.55.132] [LOG]   [MQTT bridge] MQTT message received. Topic: DahuaVTO/VideoTalkLog/Event, message: {"Action":"Pulse","Data":{"EndState":"Missed","LocalNumber":"9901","LocaleTime":"2024-07-23 17:15:55","RealUTC":1721747755,"TalkTime":0,"UTC":1721751355}}

I suspect that I am entering the wrong data at

"YOUR-STREAM-URL"

What shall I enter? Just the IP address or something like ie.

rtsp://username:password@IPADDRESS/cam/realmonitor?channel=1&subtype=1#backchannel=0

if using pm2 to autolaunch MM, then

pm2 logs --lines=xxxx

will show you the last xxxx of the output

@Cr4z33 Hi,

think I found the problem.
You need to send streamX as value where X is the number of the stream in the configuration of MMM-RTSPStream.
You will need to configure the camera information in the MMM-RTSPStream module and only will be able to start the stream by notification

Thank you both will do as soon as I am back at home again!

Hi mate I am coming back after a long time because real life was very busy lately and I could get back at this only in the last 2 days.

So based on your reply I set mqttDictionary.js like this

var mqttHook = [
  {
    mqttTopic: "zigbee2mqtt/BTicino F20T60A",
    mqttPayload: [
      {
        payloadValue: "",
        mqttNotiCmd: ["POWERMETER"],
        mqttPayload: ""
      },
    ],
  },
  {
      mqttTopic: "DahuaVTO/VideoTalkLog/Event",
      mqttPayload: [
        {
           jsonpath: "Action", 
           conditions: [
                       {
                         type: "eq",
                         value: "Pulse"
                       },
                     ],
          mqttNotiCmd: ["videocitofono"]
        },
      ],
    },
];

var mqttNotiCommands = [
  {
    commandId: "POWERMETER",
    notiID: "POWERMETER_VALUES",
  },
  {
      commandId: "videocitofono",
      notiID: "RTSP-PLAY",
      notiPayload: "stream1" 
    },
];

module.exports = { mqttHook,  mqttNotiCommands};

Although stream1 is the one and only stream used in MMM-RTSPStream I still get no playback when the doorbell button is pressed, but if I start the stream by clicking on the module’s playback button then it works.

I paste here also the PM2 log line (note that sensitive data have been censored) when the doorbell button is pressed:

[23.09.2024 12:36.03.216] [LOG]   [MQTT bridge] MQTT message received. Topic: DahuaVTO/VideoTalkLog/Event, message: {
    "Action": "Pulse",
    "Code": "VideoTalkLog",
    "Data": {
        "EndState": "Missed",
        "LocalNumber": "9901",
        "LocaleTime": "2024-09-23 12:36:03",
        "RealUTC": 1727087763,
        "TalkTime": 0,

    },
    "Index": 0,
    "deviceType": "DHI-VTO2202F-P-S2",
    "serialNumber": "*******"
}

Can you please see why it’s not working yet? 🙏🏼
