Hello,
Instead of only allowing two tank sender modes (0-180 Ohm, 240-30 Ohm), it would be extremely beneficial to have a third sender mode called "Custom".
In this mode, the user sets the empty resistance and the full resistance. The minimum and maximum resistance should be limited to what the device is physically capable of. So Venus GX Beaglebone for example probably has min and max resistance measurement abilities.
This feature would solve all the various incompatibility with nonstandard senders and the lines of questioning common that I see with "my tank levels are backwards", and "does not report full (or empty) when it is"
