Welcome to the WetterCube Wiki
Guides, settings and help for all WetterCubes: weather, health and your home at a glance.
🚀
Install the firmware, set up Wi-Fi, get going. The web installers flash the firmware straight from the browser.📟
7-inch display, sensors, Home Assistant, airing, memory card.🛏️
A display for every room: the additional module for the Fusion.📱
3.5-inch touch display, DWD warnings, pollen, rain radar, WetterAmpel.🧊
The first smart weather display: ESP32-C3 with a 1.54-inch display.🧩
Which board do I need? Cases to print yourself.🗺️
What comes next? The whole family 2026 to 2027.Why I do this: I am weather-sensitive and wanted the important information in one central place, tailored to me. Local instead of cloud: The web interfaces run on the devices themselves and are only reachable on the local Wi-Fi; there is no cloud requirement. Google does not need to know how warm it is in my bedroom right now.
Updates and maintenance: The Fusion is the current spearhead; the Next is developed in parallel. The WetterCubePlus continues to receive updates, including new features as far as the device allows. The WetterCube only gets security updates when they are necessary.
At your own risk: You use the software and the guides on your own responsibility; I accept no liability for damage or consequences. You should roughly know what you are doing (flashing a board, setting up Wi-Fi, and with WetterCube and WetterCubePlus also crimping cables and soldering). If anything is unclear, please ask first: through the contact form or on GitHub (issues). When flashing, you can usually not break much on an ESP32, the board can be flashed again at any time; real damage is more likely to come from wrong wiring or a wrong voltage. Weather data, warnings, pollen forecast and bio-weather are for information only and replace neither official warnings (e.g. NINA, DWD WarnWetter app) nor medical advice.
WetterCube is a software project. I provide the software (firmware); you build the device yourself: buy a board, flash the firmware, design a case to your own taste. I try to offer matching cases for the individual cubes. Short build guides are at Build guide.
Language and region: The WetterCube project is currently only available in German. Because the weather data for warnings, pollen forecast and bio-weather comes from the German Weather Service (DWD), it currently only works completely in Germany. A translation into English and weather information usable worldwide are planned, but there is no fixed date yet.
In development: Fusion and Next are still in development (alpha). Errors can occur with the current versions.

💙 Thanks to PicoPixel: The LVGL UI of the WetterCubes is created with PicoPixel, a free, browser-based editor for LVGL. I am convinced by the project; this is not an advertisement or affiliate link, I earn nothing from it.
