        Would it work if u give them names like MMM-FHEM1 and MMM-FHEM2?

        Cause if u add two instances with the same name in the config i can imagine, that he will read the first value and overwrites them in the second instance. Like

        var variable = 1;
        var variable = 2;

        Output would be 2.

            @bobbob601 thx for the answer. Do you have a example how to write a module with multi-instace support?

              Having the same problem with my module… A theoretical solution could be to make node_helper multi instance aware by appending some identifier to the notification unique to the instance: ie GET_WEATHER_001… The helper triggers on GET_WEATHER and builds an array with the different notifications and payloads. It then periodically runs through the array getting the appropriate requests and sending out notifications like WEATHER_001 with the specific payload.

              Haven’t built it yet though…

                  @bobbob601 I got it working by passing a unique ID to the node helper and passing it back from the node helper.

                  https://github.com/trgraglia/MMM-MVG-LocalTransport

                  Hope this helps.

                      @bobbob601 Yup. In my case, the user provides a station ID per instance because it has to do with local transport here in Munich. So in theory, the user is already providing unique IDs and I have no need to generate them. ;)

                        every instance has already a unique identifier see here https://github.com/MichMich/MagicMirror/tree/master/modules#available-module-instance-properties

                        also the discussion in here is related to the issue https://forum.magicmirror.builders/topic/960/london-bus-status/14

                        Please create a github issue if you need help, so I can keep track
