The smartphone displaying consumption data and the radiator with a glowing device.

The ad opens with a dark blue background. A smartphone displays a monthly heating and hot water consumption report. Next to it, a radiator has a small device attached, with green concentric circles emanating from it, suggesting wireless data transmission. A laptop sits on the radiator, displaying charts and data. To the right, a vertical pipe with a meter and a circular display is shown. The text "Die ista Heizkostenabrechnung:" appears at the bottom. The scene transitions to show the text "rechtssicher, mit moderner Funkablesung und monatlicher Verbrauchsinformation." followed by "Jetzt kostenlos Angebot anfordern."
