[16:04:30.547] [LOG] [MQTT bridge] MQTT message received. Topic: cmnd/home/bathroom/mirror, message: TURN_OFF_SCREEN

the log record above means that MMM-MQTTbridge received mqtt message at the topic cmnd/home/bathroom/mirror with payload TURN_OFF_SCREEN.

The next log record

[16:04:30.639] [LOG] [MQTT bridge] MQTT -> NOTI issued: REMOTE_ACTION, payload: {action: ‘MONITOROFF’}

says that MQTTbridge issued MagicMirror’s notification REMOTE_ACTION with payload {action: 'MONITOROFF'} which is exactly what you need. So this part works well.

However, the further messages in log

[16:04:30.646] [LOG] Whoops! There was an uncaught exception…
[16:04:30.665] [LOG] MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?
[16:04:30.667] [LOG] If you think this really is an issue, please open an issue on GitHub: https://github.com/MichMich/MagicMirror/issues

says that something went wrong with the MM core. That could be the reason for not executing the command by another module.

To find out the reason, you need to localize the error. Try to disable all modules and then add modules one-by-one and find which one cause that error.
hint: to disable modules, use disabled: true within each module config.

Change also listenNoti: to false, in MQTTbridge config if you do not need to convert Noti to Mqtt messages. So the module will not check all incoming MM’s notifications.

Here is the full log within my setup, I just sent a simple message to issue noti TEST with payload message:

Hmm, not really sure what changed. I’ve tried setting the notilisten to false, and then I don’t see the error, but after reactivating it, I still dont’ see it.
I can see that the log reports state 0x6 when the monitor is on, and 0x2 when it’s off.
I can send commands to the Remote_Control module via http api, but nothing happens when I try it via the mqttbridge.
I guess I have to ask @Jopyth about that?

I also tried changing the quotation markings in the dict file, to match the Remote_Control parameters in the examples, but no change :-(

var mqttNotiCommands = [
    {
      commandId: "MONITOROFF",
      notiID: 'REMOTE_ACTION',
      notiPayload: '{action: "MONITOROFF"}'
    },
    {
      commandId: "MONITORON",
      notiID: 'REMOTE_ACTION',
      notiPayload: '{action: "MONITORON"}'
    },
    {
      commandId: "UNDIM",
      notiID: 'REMOTE_ACTION',
      notiPayload: '{action; "BRIGHTNESS", value: "100"}'
    },
    {
      commandId: "DIM",
      notiID: "REMOTE_ACTION",
      notiPayload: '{action: "BRIGHTNESS", value: "75"}'
    },
    {
      commandId: "RESTART",
      notiID: "REMOTE_ACTION",
      notiPayload: '{action: "RESTART"}'
    },
  ];

@fribse said in MMM-MQTTbridge:
notiPayload: '{action; "BRIGHTNESS", value: "100"}'

attention the syntax is not correct

try wih:

notiPayload: '{action: "BRIGHTNESS", value: "100"}'

fribse

@Bugsounet Thanks, it doesn’t change the behaviour though :-)

Darned, I just found the problem.

I had this in the mqttdictionary:

var mqttHook = [
    {
      mqttPayload: "TURN_OFF_SCREEN",
      mqttNotiCmd: ["MONITOROFF"]
    },

But I was sending a MQTT message with ‘MONITOROFF’, if I send ‘TURN_OFF_SCREEN’ it works perfectly :-)

Thankyou @Serge and @Bugsounet for this GREAT module, just the missing piece.
Now I have to figure out about the noti->mqtt thing, I can see that the monitor status is reported in the log, but I can’t see what ‘notification’ is sent…

P.S. the logfile looks a bit weird:

0|mm  | [MQTT bridge] MQTT message received. Topic: cmnd/bathroom/mirror, message: MONITORON
0|mm  | [MQTT bridge] MQTT -> NOTI issued: REMOTE_ACTION, payload: **[object Object]**

But it works…

Serge

@fribse , finally it works for you. So the reason was the incorrect config initially as I understood.

P.S. the logfile looks a bit weird:

log means that the payload of the noti is an “object” and not other type of data.

Now I have to figure out about the noti->mqtt thing,

Exactly the same as for mqtt->noti: create an noti->mqtt dictionary and that is, literally, all.

I can see that the monitor status is reported in the log, but I can’t see what ‘notification’ is sent

here author https://github.com/Jopyth/MMM-Remote-Control#system-control wrote that Noti USER_PRESENCE: true or USER_PRESENCE: false is issued by the MMM-Remote-Control.
So configure your noti dictionary with these lines and you will get mqtt as soon as the USER_PRESENCE: true\false arrive. Pay attention, that the same noti could by issued by other modules, e.g.

Also, you can control other modules via mqtt-noti command. Starting from hiding/showing and ending with direct control. Examples:
Within your smarthome ecosystem based on MQTT/HomeAssistant (HA) - a great modules are

MMM-NewPIR - use your PIR sensor, integrated into MM as an instance within HA ecosystem and add it states to the scenes automation.
MMM-Youtube, - send mqtt->noti to this module and control via HA scenes e.g. turn-on news on Youtube in the morning etc.
MMM-Volume, set and turn-on/off the volume (e.g. during the day/night time)
Google Assistant etc.

Also, just a hint: add to ignoreNotiSender a default “clock” module. I will add this by default to the next release. The reason: “clock” module sends notification every second. So adding “clock” to ignored list will prevent MQTTbridge from checking “clock’s” notification in dictionary every second (just to save rpi cpu usage).

fribse

@Serge Yes, I did most of this already, I used the MMM-ViewNotifications to monitor which notifications was sent, and added all those I am not interested in :-)
Thankyou for the followup.

Serge

here is fribse’s great tutorial for simple integration of MM into Home Assistant ecosystem.
Following the logic from his post, user can expand it and control everything on its MM:

Hi @Serge , I found one thing missing from the noti->mqtt, the QOS is not settable.
I can see that you send them with qos:0, it should be settable to 0,1 or 2 as to how much guarantee for delivery it’s supposed to get.
Other than that, it’s working perfectly, even via Google Home to turn the screen on and off (via the switch in Home Assistant)

This looks very interesting! Thanks a lot for the effort to create this module. I look forward to trying it :)
