Yes, that makes sense. I will followup with something on this. 

Also, looking this again, while this is an airspeed device that can provide airspeed values (when switched to 3rd party mode, which isn't easy for the user) we actually use it as a differential pressure sensor and then derive airspeed ourselves. So I might want to change header/device path to reflect that fact as well, ie: /dev/diffpressure or /dev/differential_pressure or similar.
