Change 'inputDevice' in the script to the name of your P1 gas device.
Create 3 virtual custom sensors (Aslabel: m3) and make sure the device names of these custom sensors correspond to the names of the outputDeviceConsumptionX variables in the script.
Create 3 virtual custom sensors (Aslabel: EUR) and make sure the device names of these custom sensors correspond to the names of the outputDeviceCostX variables in the script.
You can also change the cost per unit and fixed transport cost values.
