Hi @sdetweil, yes that’s correct — I opened the PR myself after figuring out that SpotTheStation was shut down in June 2025.

The fix replaces the old RSS feed from SpotTheStation with the N2YO API. The module is already working again on my own MagicMirror with the updated node_helper.js. I’ve also updated the README and fixed the default coordinates as requested by @daterrell.

The PR is now awaiting merge: https://github.com/daterrell/MMM-ISS/pull/8

Nidra57

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
 * Node Helper: MMM-ISS
 *
 * By Dave Terrell
 * MIT Licensed.
 *
 * Modified to use N2YO API instead of NASA SpotTheStation
 * (SpotTheStation was shut down on June 12, 2025)
 *
 * Requires a free N2YO API key from https://www.n2yo.com/api/
 * Add `apiKey: 'YOUR_KEY'` to your module config in config.js

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?
