    @stro MagicMirror is a web page.
    It displays html. The modules generate a small section matching their requirements, and mm injects that onto the page in the configured position.

    The module can get it’s data from anywhere. API, file system, database.

    You have an API, which returns data, not html. Some code has to convert the data into displayable html

      @sdetweil thanks for helping me.

      I have the code (pastebin) who put the data, i‘m looking for, in a HTML Output. If i open the html file like this

      file:///home/pi/MagicMirror/modules/test/mopidy.html
      

      everything is okay.

      But if open this HTML File with the Mirrorpath like this:

      localhost:8080/modules/test/mopidy.html
      

      It shows me nothing. And i wonder why.

        @stro open the developers window, ctrl-shift-i, select the console tab and scroll up to see any errors

          Check your

          mopidy.conf

          located at:

          ~/.config/mopidy/mopidy.conf
          

          Look for this section:

          [http]
          enabled = true
          hostname = 127.0.0.1
          port = 6680
          static_dir =
          zeroconf = Mopidy HTTP server on $hostname
          allowed_origins =
          csrf_protection = true
          

          Take note of the hostname part.
          If your’s looks like the above instead of using localhost in the url, use the ip address or host name of the mirror.

          Examples:
          mirror.local:8080/modules/test/mopidy.html
          or
          10.x.x.x:8080/modules/test/mopidy.html

          I tested the code you posted on pastebin and it works as expected for me.
          Only tested using the hostname of the Mirror from external browser. Not locally on the machine.

            I was able to solve that problem.
            MPD port was double busy. Apparently 2 instances of Mopidy were running.

            Now the module MMM-MPD runs under a few specials:

            During the installation the folder name has to be changed according to the config file.
            The config file value maxRows must not be 0!
            The display will only update after a song change!

            It was hard to find this specifics, but I thank everyone for the help!

                Something like this happens to me, but my module is from user coderpussy @github , pretty new fork, maybe I got some failure from moodeaudio devs, but I dont think, so anyway here is some of my errors.

                if change folder name mmm-mpd to mpd_client errors in MM startup:

                  @dnj0104 there is probably more to the error message this also happens when there is some library required by a module not found at startup

                  u can also run

                  npm run config:check 
                  

                  to review any syntax errors in the config.js file

                    in magicmirror/modules

                    or in magicmirror/modules/mpd-module ?

                    Thinks the whole module has to be rebuilt…
