shal we have FMB003 devices and the can.fuel.volume shows a reasonable accurate fuel level reading in liters.
The only thing we noticed is that during a trip the fuel level in liters goes up and down (assuming this is normal). With can.fuel.level we see the fuel level in percentage ... but it never goes to 100%, even when completely filling up.
e.g. when adding 47 liters of fuel in a car with a fuel capacity of 53 liters only shows 83% full.
We'd like to detect a re-fueling event to estimate how much was re-fueled at which odometer.
