Real-Time Dashboards

• Solar: Monitor daily production and inverter performance.
• Wallbox: Track our EV charging activity.
• Weather: Check our local conditions and multi-day forecasts.
• Indor Air Quality: Indoor air quality of selected rooms.

At the heart of my forecasting work now lies the groundbreaking Fusion forecast, a key step in the evolution of solar prediction: it unites the learning power of AI with the physics of GTI, dynamically learning the optimal balance between them, applying adaptive weights and offsets, and delivering more robust results under unusual weather conditions. Alongside Fusion, you can explore my 24-hour energy production forecast for the House Roof System, generated with a custom AI model trained on more than 1500 days of historical weather and solar production data. The dashboard visualizes real-time AI predictions, GTI-based forecasts, and actual inverter production in a single chart, and includes key performance metrics (R², MAE) as well as historical accuracy tables.

Raeren

In der Gemeinde Raeren stehen zahlreiche Obstbäume auf öffentlichen Flächen, die allen Bürgerinnen und Bürgern zur Verfügung stehen. Auf einer interaktiven Karte habe ich die Standorte dieser Bäume mit Art und Anzahl visualisiert. Klickt einfach auf die grünen Pins, um mehr zu erfahren und nutzt gerne das Angebot der Gemeinde, Obst in haushaltsüblichen Mengen zu ernten. Hier geht es zur Karte der Obstbäume.

Terneuzen Through Time

Ontdek het verleden van Terneuzen aan de hand van twee unieke datasets: het kadaster van 1832 en het telefoonboek van 1910–1939. Bekijk wie de grond bezat in het oude Terneuzen, hoe het landschap was opgedeeld, en waar decennia later inwoners en bedrijven bereikbaar waren per telefoon. Twee tijdvensters, één stad – digitaal ontsloten.

De Zalige Zoekmachine

Experimentele zoekmachine voor Suske en Wiske, die probeert te reageren op volledige zinnen. Let op: de link verwijst naar een http://-site en de zoekmachine is nog in een extreem bèta-fase. Niet alle albums bevatten al complete gegevens. Mocht er iets niet werken of klopt er iets niet, stuur me gerust een mailtje: erik@f97.io.

Behind the Scenes

I am Erik Schmidt, a lifelong technologist and systems thinker. From the first home computers of the 80s to today’s AI-driven world, my focus has always been on making technology smarter, more reliable, and more human. What matters to me is building technology you can count on, every single day. Read more about my journey.

This site is served by a Raspberry Pi 3, tucked into an F-Tronic enclosure in Eynatten, Belgium. It connects to the internet via WiFi, stays online during power outages thanks to a UPS, and runs entirely on solar energy.
