Template sensor not showing up in area card

[thunem]

Can’t get my temperature from my Mill heater in the area card.

From my climate I’ve created a template sensor and sat it to the correct area… but It will not show up.

[123 (Taras)]

Add this to the Template Sensor’s configuration and see if that makes the Area card display it.

    device_class: temperature

Hi, I’ve got a similar issue here with a Sensibo.

Template config:

sensor:
  - platform: template
    sensors:
      office_temperature:
        friendly_name: "Office Temperature"
        unit_of_measurement: "°C"
        value_template: "{{ state_attr('climate.downstairs', 'current_temperature') }}"
        device_class: temperature
      office_humidity:
        friendly_name: "Office Humidity"
        unit_of_measurement: "%"
        value_template: "{{ state_attr('climate.downstairs', 'current_humidity') }}"
        device_class: humidity

I tried the solution above and restarted.
I’m not entirely sure that the templated values are in the area, the Sensibo is.
Any assistance would be greatly appreciated.

edit - added template config
