 - `read amount of fuel` - This can be used to read out how much fuel a machine still has (typically 0-99 units) and to compare it with a value of 'larger' or 'smaller'. If the configured condition is met, the action is carried out.
     `read power / liquid load` - This means that the charge of a battery or the heat storage device can be queried in percent (values ​​from 0..100) and checked for 'larger' / 'smaller' with the configured condition. If the condition is met, the action is carried out.
