WetterCubePlus/Inbetriebnahme/en

Dies ist die englische Fassung. Zur deutschen Fassung

1. Install the firmware

Option A: Web installer (recommended, no development environment needed)

Open the web installer (Google Chrome or Microsoft Edge only, because of WebSerial).
Connect the ESP32-S3 via USB-C and follow the instructions.
Careful with the "erase device" dialog: if ticked, the installer erases the whole flash, including all settings and the Wi-Fi password. Do not tick it when you only want to reinstall without losing data.

Option B: Arduino IDE – see Development. After that, everything else works through updates over Wi-Fi (no more USB needed).

2. First setup

The device starts with touch calibration: tap the 4 crosshairs one after another. Afterwards the cube opens its own Wi-Fi "WetterCubePlus-Setup".
On your smartphone (or PC) open the Wi-Fi settings, look for "WetterCubePlus-Setup" in the list of available networks and connect to it. If the phone says that the network has no internet access, stay connected anyway.
The browser now opens the cube's setup portal by itself. If that does not happen, open http://192.168.4.1 in the browser.
In the portal enter the credentials of your home Wi-Fi (choose the network, enter the password).
Enter your location without umlauts (Munchen instead of München, Koln instead of Köln, Dusseldorf instead of Düsseldorf).
Choose your DWD region / federal state (also used for the radar map).
Save. The cube restarts and connects to your home Wi-Fi. Afterwards connect your phone to your normal Wi-Fi again (this usually happens by itself).

Afterwards the cube is reachable at http://wettercubeplus.local or the IP address shown on the display.

Re-calibrate touch

Hold a finger on the display while powering on until "Neukalibrierung" appears, then let go.

If the Wi-Fi connection fails at startup

At startup the cube tries twice (15 seconds each). If that fails it shows the setup mode ("WLAN-Verbindung fehlgeschlagen"). The saved credentials are kept, and the cube automatically retries every 60 seconds and restarts on success. When in doubt, read /log (in setup mode at http://192.168.4.1/log).
