What options are there for refreshing connection when I connect power to tesla

[vw-kombi]

I mainly use this app to monitor the charging power usage - ie the sensor 'sensor.voltorb_charger_power'.
I have a yaml that reads this only when car is home, and divides by 1000 for my home assistant :

      {% if is_state('device_tracker.voltorb_location_tracker', 'home') and is_state('binary_sensor.voltorb_charging', 'on') %}
      {{ states('sensor.voltorb_charger_power') | int(0) *1000 }}
      {% else %} 
      0
      {% endif %}

This works well, however I have to manually 'refresh' the integration for it to start reading these values.

Is there something I can do to automate this ?
