Like many of you, I wanted a dedicated, always-on display for my Tempest data, but I didn’t want to rely on a tablet or a web browser.

I ended up building **Tempest Inky** —a Python-based dashboard engine that adapts its rendering style based on where it’s running.

**The “Dual Mode” Engine** The coolest part of this project is that it isn’t just for Raspberry Pi. The code detects the hardware and switches the visual engine automatically:

1. **On E-Ink (Raspberry Pi):** It renders a high-contrast, white-background interface optimized for the **Pimoroni Inky Impression 7.3"**. It uses hardware pigments (Blue/Green/Orange/Red) to avoid “muddy” dithering artifacts.

2. **On Desktop (Windows):** It switches to a sleek “Dark Mode” application with a supersampled **cubic-spline graph engine** , rendering smooth anti-aliased curves and gradient fills.

**Key Features:**

- **Dynamic Trend Graph:** Visualizes the last 24 hours of temperature data to show warming/cooling trends.

- **Smart Coloring:** Data points change color based on severity (Freezing, Cold, Mild, Warm, Hot).

- **Full Stats:** Includes “Feels Like,” Wind Speed (with km/h support) & Direction, Rain Accumulation, Humidity, Pressure, and UV.

- **Forecast:** Pulls the 5-day outlook from the Tempest “Better Forecast” API.

**Links & Downloads:** The project is open source, and I’ve put together a standalone Windows Installer so you don’t need to mess with Python environments to try it out on your PC.

- **GitHub Repo (Code & Installer):** [https://github.com/moorew/tempest-inky](https://github.com/moorew/tempest-inky)

- **3D Printed Frame:** If you are building the E-Ink version, I designed a slim, snap-fit frame for the Pimoroni screen: [https://www.printables.com/model/1522781-slim-frame-for-pimoroni-inky-impression-73-2025-sp](https://www.printables.com/model/1522781-slim-frame-for-pimoroni-inky-impression-73-2025-sp)

I’d love to hear what you think or if you have any feature requests!
