Anyone know a good alternative to this that isn't meant to be fleet-scale? Getting OBD data over Bluetooth is widespread enough, but their service also made it super easy to generate mileage expenses. Also downloading a CSV of all my trips made for some fun data crunching. I'd love to keep those things going even if it means self-hosting something.
