Wrong more-info popup style when using sensor template

Configuration
1

Hi,
in a entities card i show the value of a temperature sensor, and when i tap on the temperature, the more-info popup shows the ususal nice graph, see:
Bild2
the problem is when is use a template to round the value and get rid of the unit_of_measurement, then a different more-info popup appeers (see pic) which is not as informative.

how can i get the graph pop-up with my value-template?

my template:

      temperature_aussen_round:
        value_template: "{{ '%.1f'%(states('sensor.lumi_lumi_weather_4faae306_temperature') | float) | float }}"
        friendly_name: "Außentemperatur"
        unit_of_measurement: ""
        icon_template: mdi:thermometer

i restored my template code to
unit_of_measurement: “°C”

but unfortunately it did not help
(the entities card now shows the °C, so the editing worked)

that was it, thanks!
i changed the template to.

         unit_of_measurement: " "

the space is sufficient to be recognized as graph data.
and for a test i simply renamed the template, thus it started a new log.
Now it shows the graph :slight_smile:
