Add "percentage" behind a value

[w00p (Kjetil)]

Hi,

New to Home Assistant, and was wondering is there a way to add a % behind the value of Garasje? Just my OCD kicking in. See picture and code bellow.

type: entities
entities:
  - entity: sensor.garasjeport_battery
    name: Garasje
  - entity: sensor.hue_dimmer_switch_1_battery_level
    name: Hue dimmer
  - entity: sensor.living_room_battery
    name: Stue
  - entity: sensor.inngangsdor_battery
    name: Inngangsdør
show_header_toggle: false
state_color: false
title: Batterinivå

Cuatimoze the sensor and change the device class to battery. Either though the UI under

Customizing entities

homeassistant:
  customize:
    sensor.garasjeport_battery:
      device_class: battery

Or through the UI (steps explained in the linked docs).

Thank you! That got me in the right direction! it already was device_class: battery" but I added unit_of_measurement: '%' and now its good
