Need help with MMM-MQTTbridge not "communicating" with MMM-RTSPStream

[Cr4z33]

So long story short what I want to achieve is to show my video doorbell live feed for 15 seconds on my smart mirror whenever someone presses its button.

Therefore I want to use MMM-MQTTbridge to detect the doorbell MQTT line with code

2025-04-16 11:40:58,897 INFO __main__ Publishing MQTT message DahuaVTO/Invite/Event: {'Action': 'Pulse', 'Code': 'Invite', 'Data': {'CallID': '3', 'IsEncryptedStream': False, 'LocaleTime': '2025-04-16 11:40:58', 'LockNum': 2, 'RealUTC': 1744796458, 'SupportPaas': False, 'TCPPort': 37777, 'UTC': 1744800058.0, 'UserID': '101'}, 'Index': 0, 'deviceType': 'DHI-VTO3311Q-WP', 'serialNumber': '*******'}

and send the RTSP-PLAY command to MMM-RTSPStream to play its video feed.

This is the MMM-MQTTbridge config.js section:

	{
		module: 'MMM-MQTTbridge',
		disabled: false,
		config: {
			mqttServer: "mqtt://:@ipaddress:port",
			mqttConfig:
			{
				listenMqtt: true,
				interval: 500,
			},
			notiConfig:
			{
				listenNoti: true,
				ignoreNotiId: ["CLOCK_MINUTE", "NEWS_FEED"],
				ignoreNotiSender: ["system", "NEWS_FEED"],
			},
			// set "NOTIFICATIONS -> MQTT" dictionary at /dict/notiDictionary.js
			// set "MQTT -> NOTIFICATIONS" dictionary at /dict/mqttDictionary.js
			},
	}

This is the MMM-RTSPStream config.js section:

{

module: "MMM-RTSPStream",

position: "middle_center",

disabled: true,

config: {
autoStart: false,
rotateStreams: true,
rotateStreamTimeout: 10,
moduleWidth: 500,
moduleHeight: 281,
localPlayer: 'vlc',
moduleOffset: { left: -170, top: -125 },
remotePlayer: 'ffmpeg',
showSnapWhenPaused: false,
remoteSnaps: false,
shutdownDelay: 12,
stream1: {
name: 'Videocitofono',
url: 'rtsp://username:password@doorbellip/cam/realmonitor?channel=1&subtype=1#backchannel=0',
frameRate: 'undefined',
width: 500,
height: 281,
muted: true,
ffmpegPort: 9999,
},
}
}

And finally this is the content of mqttDictionary.js:

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

Looking at MM and PM2 logs there’s neither a single trace of that MQTT line being detected nor the feed being playbacked.

Perhaps someone of you skilled people can please help me? 🥺

The author of MMM-MQTTbridge is busy at work and therefore cannot help.

[sdetweil]

@Cr4z33 if you set

debug:true

in the MMM-MqttBridge config in config.js

it will output messages at npm start

i always recommend not using pm2 while testing
as you can see the messages from npm start easily

@Cr4z33 said in Need help with MMM-MQTTbridge not "communicating" with MMM-RTSPStream:

MMM-RTSPStream

The position is incorrect. There is no middle\_center position.

[sdetweil]

@mumblebaj AND with release 2.30 or higher a message will be sent to the stderr stream that this module will not be loaded

good catch

[sdetweil]

@mumblebaj WELL… it turns out this is a false warning as _ is treated as _ in js…

I changed the position middle_center1 and got

@sdetweil sorry for being gone for so long time, but I’ve been out of town more than scheduled. 😅

So back in topic… the typo for the MMM-RTSPStream config section was done in this forum post only.

Where did you get all those warnings from?
Looking at npm start output nothing like that was displayed (on my side).

On the other hand I could see this when I launched that command with MQTTbridge log set to true:

[29.04.2025 09:57.21.030] [LOG]   [MQTT bridge] Subscribed to the topic: DahuaVTO/Invite/Event

So the module is somehow doing something, but then as I said nothing happens at button press.

[sdetweil]

@Cr4z33 as i said the \- in the position is ok,
i made the position invalid by adding a 1 at the end, then the bad position output is shown from npm start

still no activity from the button
two things

1. the event is not triggering to mqtt
2. the action in mqttbridge is not what you expected

i dont know how to debug either one

[Cr4z33]

@sdetweil it’s OK mate and thanks for having tried to help me. :)

Let’s hope someone can come up with a working solution soon.

[sdetweil]

@Cr4z33 looking further at mqttbridge it also logs receipt of the notification from the subscription

so that tells me it did not receive info from mqtt

[Cr4z33]

@sdetweil I am not quite sure that I understood.

Are you saying it’s a module’s bug or is it needed further coding I should add (somewhere)?

[sdetweil]

@Cr4z33 im saying the module will report when it receives the mqtt info. it did not report. sooooo it did not receive the info

why i do not know

[Cr4z33]

@sdetweil hmmm I see.

I wonder if there’s actually another way to see the doorbell stream when the button is pressed?

There’s a button sensor entity for it in Home Assistant.

[sdetweil]

@Cr4z33 i dont know, but MQTTBridge was not informed of the button press as you expected

is your other bridge code running? you mentioned you had some app talking to the doorbell and publishing the mqtt message

is the doorbell an mqtt device , fed thru zigbee2mqtt for homeassistant?
or is there a native integration?
i would expect the doorbell to NOT publish to mqtt directly
it would be a tiny market to add and support that code IN the doorbell firmware

[sdetweil]

@Cr4z33 you could build an HA automation to send the MQTT message on button push

[Cr4z33]

@sdetweil said in Need help with MMM-MQTTbridge not "communicating" with MMM-RTSPStream:

But then again nothing would happen.

I mean I’ve already DahuaVTO2MQTT in the middle and I used the right line taken from its console, but here we are. 😅

[sdetweil]

@Cr4z33 something is not sending the mqtt message

bell -> ha automation -> mqtt -> mqttbridge -> rtsp…
should work

for me, this works

alexa-> nodered -> mqtt > ha automation -> mqtt -> mirror_app -> screen off

And you are using this MQTT module on the smart mirror or?

[sdetweil]

@Cr4z33 no, i wrote my own code for the mqtt integration

but its fundamentally doing the same thing, receiving an mqtt message and sending a notification to other code to act

[Cr4z33]

@sdetweil I see I wish I had the same skills to do ALL by myself lol!

However I wonder if I am the only person in the world having a smart video doorbell and MagicMirror?

I mean I haven’t found any universal solution to this in this forum, but just some modules for certain doorbell hardware like Ring, etc.

[sdetweil]

@Cr4z33 and the ring module talks directly to the ring doorbell

you should be able to use HA automation to get to mqttBridge, no fancy coding

automation trigger
device bell button push
action, more, command, mqtt publish

i have ring doorbell, and the module doesnt work for me
doesnt matter, as im hardly ever in front of the smartmirror when the doorbell rings
there is a ring2mqtt docker container, but again it really doesnt add anything useful
