Can't make sense of trip.fuel_consumed

[masve64]

Hi, thanks for a great work :-)

I've been fetching data from Toyota, and doing so looking at the trip.fuel_consumed data, metric=True, on a trip, I'm presented with following information:

Km/Liter
Trip start time: 2024-02-04 10:04:40+00:00 - (55.849, 12.4852)
Trip end time: 2024-02-04 10:25:14+00:00 - (55.8413, 12.2868)
Fuel consumed. 0.248000
Ev dist: 4.899000
Ev duration: 0:08:29
Dist: 16.602000

However if I choose metric=False, I get the following information:

Miles/Gallon
Trip start time: 2024-02-04 10:04:40+00:00 - (55.849, 12.4852)
Trip end time: 2024-02-04 10:25:14+00:00 - (55.8413, 12.2868)
Fuel consumed. 0.248000
Ev dist: 3.044000
Ev duration: 0:08:29
Dist: 10.316000

According to my car my fuel consumption is 14,7km/liter, and according to my Toyota APP it's shows 7L/100km (just about the same)

So how do I get from fuel_consumed = 0.248000 liter to something that match what my Car or the APP data ?

Looking in the class trip code, fuel_consumed:

@property
def fuel_consumed(self) -> float:
    """The amount of fuel consumed.

    Returns
    -------
        float: The fuel consumed in liters if metric or gallons
    """
    if self._trip.summary.fuel_consumption:
        return (
            round(self._trip.summary.fuel_consumption / 4546.0, 3)
            if self._metric
            else (self._trip.summary.fuel_consumption / 1000.0)
        )

    return 0.0

However looking in class summary, fuel_consumed is calculated diffrently:

@property
def fuel_consumed(self) -> float:
    """The total amount of fuel consumed.

    Returns
    -------
        float: The total amount of fuel consumed in liters if metric or gallons
    """
    if self._summary.fuel_consumption:
        return (
            round(self._summary.fuel_consumption / 1000.0, 3)
            if self._metric
            else round(self._summary.fuel_consumption / 3785.0, 3)
        )

    return 0.0

Hi @masve64. Looks like we have a discrepancy and the formula for converting mililiters to gallons in the trips model is currently incorrect. Should be fixed in next version: #327 Thx for reporting it 😊

But the way you describe it, you don't want the total fuel consumed (fuel_consumed) but the average fuel consumption (average_fuel_consumed): https://github.com/DurgNomis-drol/mytoyota/blob/master/mytoyota/models/summary.py#L168

Thanks, if for metric=True I can assume that the fuel consumed is for the entire trip, then 0,248 Liter consumed for 16,6 km => 66,9km/liter, it did not make any sense (evenhough it's a RAV4 Hybrid) ;-)

As I said before, the formula in the trips model is currently wrong 😉
