Getting Temperature shown, not status in Floorplan

Hey All,

Just playing around with the floor plan, and have no more idea.
My sonoff_trvzb_thermostat is added to the floor plan, but its only showing “heating” or “off”

How can I get the actual and / or set temperature shown in the floor plan?
If i create a Entitys card it shows “Heating”. Actual Temp, Target Temp.
So the values are there, how do i get them into my floor plan template?

This is the actual demo code:

type: picture-elements
elements:
  - type: state-badge
    entity: climate.sonoff_trvzb_thermostat
    style:
      top: 32%
      left: 40%

Tried to add also this code, but dont know where and how

sensor:
  - platform: template
    sensors:
      frametv_title:      
        friendly_name: Test
        entity_id: 
          - climate.sonoff_trvzb_thermostat
        value_template: "{{ state_attr('climate.sonoff_trvzb_thermostat', 'current_temperature' }}"

Maybe someone can help to understand what to add to the template to get the temperatures shown

No one any idea?
