Failed to fetch observation stations: HTTP ${stationsRespons

Error message

Failed to fetch observation stations: HTTP ${stationsResponse.status}

What it means

To find the nearest observation station, #fetchWeatherGovURLs fetches the stations collection for the grid point. A non-ok HTTP status (embedded in the message) aborts initialization with this Error.

Solutions

1. Check the status: 429/503 means rate limited or down — increase the updateInterval and retry later.
2. Verify api.weather.gov health at status.weather.gov for 5xx errors.
3. Reduce polling frequency so you stay under NWS rate limits (user-agent identified clients are expected to poll sparingly).
4. If only current-weather observation fails, consider type "forecast"/"daily" which does not need stations.

Example fix

// before
config: { weatherProvider: "weathergov", type: "current", updateInterval: 60000 } // too aggressive
// after
config: { weatherProvider: "weathergov", type: "current", updateInterval: 600000 }

// verify the stations endpoint before enabling type "current"
const r = await fetch(`${forecastGridpoint}/stations`, { headers: { "User-Agent": "MagicMirror" } });
if (!r.ok) throw new Error(`stations pre-flight failed: HTTP ${r.status}`);

async function initWithRetry(provider, tries = 3) {
  for (let i = 0; i < tries; i++) {
    try { await provider.initialize(); return; }
    catch (err) {
      const m = err.message.match(/HTTP (\d+)/);
      const retryable = m && (m[1].startsWith("5") || m[1] === "429");
      if (!retryable || i === tries - 1) throw err;
      await new Promise(r => setTimeout(r, 2 ** i * 30_000));
    }
  }
}

When it happens

Trigger: GET to the grid point's stations endpoint returns 404 (grid point has no station list), 429/503 (rate limit or NWS outage), or any other non-ok status.

Common situations: NWS API rate limiting after frequent polling (MagicMirror's default interval); api.weather.gov incidents; requesting stations for remote/ocean grid points with sparse coverage.
