Home connect translate entity values

Hi!
How can i translate the entity values for the Operation State?

If you mean from like “on”, “off” to “ein” “aus” for example then you could use templates and create another entity that uses the original entity’s state in the it’s value_template but translates the state names:

The following example basically translates the state name “on” to “Auf”

sensor:
  - platform: template
    sensors:
      window_bath_sensor:
        friendly_name: 'Badfenster'
        value_template: "{% if is_state('binary_sensor.window_bath1', 'on') %}Auf{% else %}Zu{% endif %}"
