WetterCubePlus/Diagnose und Fehlersuche/en
Dies ist die englische Fassung. Zur deutschen Fassung
Reading /log
The cube keeps a small log in memory (the last 40 entries, empty after a restart). Open it in the browser:
- during normal operation:
http://wettercubeplus.local/log(or click Log ansehen in the "Firmware-Update" card of the web interface) - in setup mode (phone on the "WetterCubePlus-Setup" network):
http://192.168.4.1/log
| Header line | Meaning |
|---|---|
| Aktueller freier Heap | free internal RAM, with the lowest level since start in brackets |
| PSRAM | free external RAM (of 8 MB), lowest level, largest free block |
| Uptime | minutes since start |
| LVGL-Speicher | "Pool im PSRAM" with the free PSRAM |
| Letzter Neustart | power connected, software restart (e.g. after an update), crash, watchdog or brownout |
| WLAN beim Start | duration and signal strength, or the failure reason |
| WLAN jetzt | network, signal strength and IP address |
| Standort | city with coordinates (0.0000 means: not found yet) |
| Letzter erfolgreicher Abruf | how long ago the last successful request per data source was (weather, DWD pollen, pollen/air, DWD warnings, radar, biowetter) |
| Update | installed and latest known version, last check |
| Letzte /api/ampel-Anfrage | how long ago the WetterAmpel last reported (normally 30 s at most) |
Below are the events, newest first. Successful requests are not listed one by one (the log would fill up quickly); they appear as a time in the header instead. Failures are listed with their reason:

Common problems
| Problem | Cause and remedy |
|---|---|
| Cube shows the setup mode although Wi-Fi was configured | "WLAN-Verbindung fehlgeschlagen": the credentials are still saved. Is the router reachable? Is 2.4 GHz Wi-Fi active? The cube retries by itself every 60 seconds. The reason is in /log under "WLAN beim Start"
|
| "Bitte den WetterCube konfigurieren" | The settings are empty (e.g. after "erase device" in the web installer). Repeat the first setup |
| Glitches after plugging in | Suspect power supply/cable: does /log say "Letzter Neustart: BROWNOUT"? Use a supply of at least 5 V / 2 A and a short cable
|
| Wi-Fi reason "Netzwerk nicht gefunden" | Name misspelled, router too far away or only 5 GHz active |
| Wi-Fi reason "Passwort?" | Wrong password: enter it again via the portal |
| Update icon does not appear | It only appears when a newer version is released, and only on the main screen. In the web interface "Auf Updates prüfen" forces an immediate check |
| Update aborts with "download error" | GitHub Pages sometimes serves the new firmware only after a few minutes. Wait a moment and retry |
| Weather values stand still | Look at /log: fetch errors are listed there with the heap level. The lowest levels show whether memory was tight
|
| Traffic light always shows the same color | Check "Letzte /api/ampel-Anfrage" in /log: well above 30 s means the light is not reporting (check Wi-Fi or the device)
|
| Touch is off | Hold a finger on the display while powering on and re-calibrate |
