Update interval of homeassistant sensor in ESPHome for use with Gree AC I-Feel feature

I’m using a Xiaomi IR Blaster device to control my Tosot (Gree) AC device.

climate:
  - platform: heatpumpir 
    protocol: greeyac
    name: "Woonkamer airco"
    horizontal_default: middle
    vertical_default: auto
    max_temperature: 30
    min_temperature: 16
    sensor: current_temperature
    receiver_id: rcvr

Since the internal temperature sensor is quit inaccurate, I would like to use the current_temperature value from my wall mounted thermostat.

This feature is available on the ESPHome IR Remote Climate component:

The greeyac protocol supports a feature Gree calls “I-Feel”. The handheld remote control has a built-in temperature sensor and it will periodically transmit the temperature from this sensor to the AC unit. If a sensor is provided in the configuration with this model, the sensor’s temperature will be transmitted to the greeyac device in the same manner as the original remote controller. 

For this I configured a home assistant sensor in my ESPHome configuration to get the current temperature value from my thermostat:

  - platform: homeassistant
    id: current_temperature
    entity_id: climate.woonkamer
    attribute: temperature

and whenever I use the IR component to control the AC, or when the value for climate.woonkamer.temperatue changes, the current temperature is send correctly:

14:49:17	[D]	[climate:385]	'Woonkamer airco' - Sending state:
14:49:17	[D]	[climate:388]	  Mode: HEAT
14:49:17	[D]	[climate:393]	  Fan Mode: AUTO
14:49:17	[D]	[climate:405]	  Swing Mode: OFF
14:49:17	[D]	[climate:408]	  Current Temperature: 20.00°C
14:49:17	[D]	[climate:414]	  Target Temperature: 17.00°C

The value however needs to be send to the AC via IR every few minutes (recommended interval: 2 minutes)

How often the temperature is transmitted is determined by the update_interval assigned to the sensor. Note that update_interval must be less than 10 minutes or the greeyac device will revert to using its own internal temperature sensor; a value of 2 minutes seems to work well. See Sensor Component for more information.

The platform: homeassistant sensor however does not support the property of update_interval.

How can I overcome this limitation and make the IR blaster send a temperature update every 2 minutes, even though the value did not change?
