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

Cr4z33

@sdetweil and how would I get the broadcasting of the doorbell video feed?

Custom coding?

sdetweil

@Cr4z33 same rtspstream, that part of your solution didn’t change

button -> ha automation -> mqtt publish -> mqttbridge -> notification to rtspstream to open and connect video feed

altho you may have to use
https://github.com/evroom/MMM-MPlayer
instead of rtspstream module

and install MMM-ViewNotifications to see the events sent inside MagicMirror

@sdetweil hmm I want to give it a try tomorrow morning (GMT+2).

Would you mind if I might contact you by PM just in case? 🥺

sdetweil

@Cr4z33 no problem. i am US Central UTC-5

Hi and sorry fir the late reply…
Your config of the MQTT module is still missing a “debug: true”. The messages only get logged if debugging is enabled.

	{
		module: 'MMM-MQTTbridge',
		disabled: false,
		config: {
                        debug: true, 
			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
			},
	}

@wishmaster270 yes, we covered that before

sdetweil

@wishmaster270 i’ve come to the conclusion

the doorbell itself does not publish to mqtt
MqttBridge did not get any message from its subscribe

he is going to try to build a HomeAssistant automation, as it CAN see the doorbell button thru its integration

Cr4z33

@wishmaster270 thanks for spending some time on my issue although you’re busy.
As sdetweil said he’s already helping me into this. 🙂

@sdetweil my bad, my bad and again my bad! 😓

I was going to tryout your method when I realized I actually never checked deeply what was outputting npm start… There’s A LOT of doorbell data being captured by MMM-MQTTbridge indeed! 🤦🏼

You can see here the output.

Can you see at this point (maybe) some additional data that needs to be added to mqttDictionary.js or do you still believe I should go your way (HA, automation, etc.)?

While waiting for your kind reply I will play at trying your method. 😁

@Cr4z33 Good afternoon,
I do not have the time to dig too deep into MMM-MQTTbridge …
But what I see checking your console logfile and compare this to your first posting:
You obviously had managed that the MQQT message arrives and is acknowledged.

.
The message you receive is:

{
    "Action": "Pulse",
    "Code": "Invite",
    "Data": {
        "CallID": "5",
        "IsEncryptedStream": false,
        "LocaleTime": "2025-04-30 10:40:43",
        "LockNum": 2,
        "RealUTC": 1746002443,
        "SupportPaas": false,
        "TCPPort": 37777,
        "UTC": 1746006043.0,
        "UserID": "101"
    },
    "Index": 0,
    "deviceType": "DHI-VTO3311Q-WP",
    "serialNumber": "****"
}

This is what you trying to capture in your mqttDisctionary.js
I’m not 100% sure if you

catch the right data-value : - is your jsonpath correct?
is “notiID” the right place for the module name you try to reach?

Just spontaneous thoughts about your issue - maybe misleading …

Ralf

@rkorell hi it’s a good question indeed.

However too bad that I am not skilled enough to know the answer lol that’s why I am posting here asking for help! 😂

Let’s see if @sdetweil or someone else can find out.

sdetweil

@Cr4z33 woohoo, i see the data, now its MQTTBridge configuration, and that part i dont know (yet)

rkorell

@Cr4z33 OK, I guess you have to dig a little bit deeper into MMM-MQTTbridge …
You may give MQTTbind a try - this seems to be easier and more straightforward…

In addition: I’m not really sure if your RTSP-play module is able to react on notification - had you double-checked this? (If it does not react on notification, you cannot be successful…).

Regards,
Ralf

rkorell

@rkorell @Cr4z33 with writing the above I’ve just noticed:
Your RTSP module is NOT “RTSP-play” but "MMM-RTSPStream" !
This should be your first trial then in your mqttDisctionary.js …

sdetweil

@rkorell MMM-MPlayer should work for displaying on notification

rkorell

@sdetweil cool.
had played around with this and it was frickling to position - but worth a try … :-)

@Cr4z33 just found “source” : you have copied this configuration .
But I bet you have to place the module name as “notiID” …
this is not “RTSP-play” but “MMM-RTSPStream” …

(Pay attention : it is highly probably case-sensitive …)

rkorell

@Cr4z33
MMM-RTSPStream is quite old and the author himself doesn’t use it anymore and recommend indeed other modules.
So it a a wise advice from Sam (@sdetweil ) to use MMM-Mplayer …
This one still have an active discussion here .

Ralf

rkorell

@rkorell said

use MMM-Mplayer …

Just checked: You CAN use MMM-Pages notification to start and stop your stream …
(e.g. “NEW_PAGE=0” will start the stream.

Unfortunately you will have to care about switching OFF the stream by yourself - I guess the doorbell will not be sufficient to send a “STOP” signal - You likely would to see the stream longer that the visitor is pressing the doorbellbutton …

Thank you again @rkorell and @sdetweil for your precious help, but I am at a point where I don’t have enough skill to generate the needed code lines.

What comes afterwards (ie. stop the stream, etc.) is not what worries me hehe, but all I am able to do at today is how to install a module and give it a basic config.

Having two modules to “talk” to each other is another matter and that’s where I start asking for help to people who know what they are doing (I am more a copy&paste or a tutorial follower guy). 😁

Once again this is the RTSP URL:

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

and this is the MQTT button press line:

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': '*******'}

I tried creating a Home Assistant automation, but it’s probably wrong.

sdetweil

@Cr4z33 you are composing a service that does not yet exist
button on doorbell causes window w video stream to
open

appears no one has done that w this video doorbell, welcome to the bleeding edge. u get to MAKE the sausage no one else wants to see!!

a MagicMirror module runs inside a web browser, all in javascript. it can consume info from the outside using url based apis http get or put/post

Now, sometimes, you want module A to work with data from module B. for example calendar. it reads the raw data file (ical/ics), parses all the events, gets the list of pertinent events ( dont care about 2 years ago, only next week…)

and displays them. hm id like a different display, but dont want to learn about all the file reading and parsing and selecting)

MagicMirror provides a way for one module to share its data with others, called Notifications. some identifying string, with some attached data. the mechanism is a broadcast. one send, every other module gets the same message.

if a modules doesn’t understand the identifying string, it ignores the message
if it DOES understand the identifying string, then it MUST understand the format of the attached data.

so, modules that DO participate in this data sharing must document ( in their readme.md file)

what notification strings they send (and its associated data format, if any)
AND
what notifications strings they accept (and its required data format)

nothing going outside the browser is known inside the browser,
to get that kind of info requires some module to be able to bridge the two environments

i have a simple one
id like some way for a script running outside MagicMirror to trigger a module to do something (receive a notification it knows about)
so i wrote MMM-CurlToNotification
from the command line outside MagicMirror you can issue the curl command to send a packet of data that turns into a notification sent to all modules
there are other modules that provide similar support (as well as others), mmm-remotecontrol for example

anyhow MMM-MqttBridge does that bridging for MQTT messages. in both directions

mqtt -> notifi(cation) and notification) -> mqtt

but you need to know a bunch of stuff, and figure out how to code the file that does the actual work

i work backwards
i need a video played from a url on demand
what modules can do that
and how do i setup for the on demand part

pick a module RTSPStream or Minfo, read its doc to understand what notifications it understands, and what data it needs

install and configure the selected module

now you ‘could’ use my curltonotification module to verify that the video player module works

then you back up to the MQTT bridge module config to send the same message you just tested with, and what mqtt message will trigger it

then back up, and find/setup what will send that mqtt message
and how it is triggered to to that

you can draw this all out on a piece of paper

coding is just making the computer fo the exact same thing over and over, just faster. if you dont know what, then it cant either

someone presses the doorbell button
how does something outside the doorbell know?
can that something send a msg via mqtt that the bridge is listening for? if not, can i find something that that can take the first things out and get it into our expected mqtt message

repeat along the way,
test each step
