MMM-ISS by daterell

[Nidra57]

I tried to install the module , but I don’t get any data on my mirror, just “Next ISS fly over”, “Visible”, “Max Height” “Appears” and “Disappears”. Has anyone have suggestions to solve this?

{
  module: 'MMM-ISS',
  position: 'bottom_right',
  config: {
    // These values must come from available locations on the SpotTheStation site: https://spotthestation.nasa.gov/
    country: "Netherlands",
    region: "Flevoland",
    city: "Almere",
    minElevation: 40 // 40 Lowest elevation for the panel to show up
  }
},

Oorzaak:
NASA heeft SpotTheStation op 12 juni 2025 offline gehaald, waardoor alle MMM-ISS installaties wereldwijd niet meer werken.

Oplossing:

• gratis N2YO API-sleutel aanvragen op n2yo.com/api
• node_helper.js herschreven om de N2YO API te gebruiken — zonder dat de rest van de module aangepast hoeft te worden.

Config.js:

{
  module: "MMM-ISS",
  position: "bottom_right",
  config: {
    apiKey: "JOUW_N2YO_SLEUTEL",   // ← nieuw
    lat: 52.37,
    lng: 5.22,
    units: "km",
    minElevation: 40
    // country, region en city zijn niet meer nodig
  }
},

Node helper.js:

/* Magic Mirror

@Nidra57 please , code block around config, log, js

There could be errors shown in the place you start MagicMirror

If pm2, then

pm2 logs —lines=xxxx

Where xxxx is the count of most recent lines, default 15
