A man directly addressing the viewer and holding a smartphone with a visually interesting app interface.

The video opens with a man, Fabian Zeller, Head of Product & QA - App & Web at 1KOMMA5°, speaking directly to the camera. He is in a modern, well-lit space with vertical accent lighting and what appears to be energy-related equipment in the background, including a wall-mounted charger and an inverter. He gestures with his hands and holds a smartphone. The scene then shifts to show him interacting with a shelf displaying smartphones and energy devices. The focus moves to a close-up of the smartphone screen, displaying the 'Heartbeat AI' app. The app interface shows energy prices, system optimizations, and usage data. The video then returns to Fabian Zeller, who continues to explain the app's functionality, emphasizing its ability to optimize energy consumption and costs. The video ends with the 1KOMMA5° logo on a purple background.
