Preferred way to substitute current temperature value for AC unit in lovelace?

Hi,

I have a Daikin AC which was very easy to discover and autocreate with the daikin integration. I got a thermostat card in lovelace to control everything I need.

entity: climate.dg
name: Klimaanlage DG
type: thermostat

climate.dg has the following attributes:

hvac_modes:
  - fan_only
  - dry
  - cool
  - heat
  - heat_cool
  - 'off'
min_temp: 7
max_temp: 35
target_temp_step: 1
fan_modes:
  - Auto
  - Silence
  - '1'
  - '2'
  - '3'
  - '4'
  - '5'
preset_modes:
  - away
  - none
swing_modes:
  - 'Off'
  - Vertical
  - Horizontal
  - 3D
current_temperature: 26
temperature: 24
fan_mode: Silence
preset_mode: none
swing_mode: 'Off'
friendly_name: DG
supported_features: 57

Unfortunatley, current_temperature is very unreliable when the AC is off. I would like to show the temperature from a temperature sensor (e.g. sensor.temp_dg) that is in the same room as the AC unit instead in lovelace.

What would be the easiest way to accomplish this ?
