how do I have to write a template to show the measured time in hours and minutes?
…and I tried to round the calculated minutes
state: "{{ states('sensor.brenndauer_tag')|float(0) * 60|round(1, 'floor', 0) }}"

Use this method to get value from the history sensor because you’re just putting it into a entities card. No point in dealing with a template when it’s already calculated for you as an attribute.
