How to detect a re-fuel event? There is a handy template to detect trips but how would we be able to detect the fuel level (pct or volume) going up?

JamesJapp calculators can analyze parameters relation of maximum two sequential messages. Also some short conditions can be combined together into single interval by using "max_inactive" in the selector. So your condition for the filling can be "(volume-#volume)>0", where volume is the name of parameter with current tank volume.
But based on our experience this may work with precise and CAN-based fuel level sensors, but usually won't work with standard analog fuel level sensors, as they are usually require special math.

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.
