Need help with MMM-MQTTbridge not "communicating" with MMM-RTSPStream
-
@Cr4z33 woohoo, i see the data, now its MQTTBridge configuration, and that part i dont know (yet)
-
@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…).

@rkorell MMM-MPlayer should work for displaying on notification
-
@sdetweil cool.
had played around with this and it was frickling to position - but worth a try … :-) -
@rkorell said in Need help with MMM-MQTTbridge not "communicating" with MMM-RTSPStream:
@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 …@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” …

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

@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=0and 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.

@Cr4z33 you are composing a service that does not yet exist
button on doorbell causes window w video stream to
openappears 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 environmentsi 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 exampleanyhow 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 partpick 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 thatyou 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 messagerepeat along the way,
test each step
