How does it not trigger the alarm once the car is locked?
And if that exception can be coded into the car, wouldn't that still drain the battery fairly fast?
Also, afaik some cars offer a lot of stats via Bluetooth (in my case various temperature of hvec, exhausts, interior, gears, power, torque, battery status, fuel left in litres, fuel used in trip, etc), so you might not need the OBD port.
This is interesting, I have this bookmarked to see how things progress after a few months.
I work on electric steering systems. There's a lot of info on the OBDII bus--depending on the complexity of the device and your particular vehicle, you could use it to track driving habits/efficiency, location, interpreting trouble codes, and plenty more. If it has some local data logging, it could even be used as a "black box" in the case of an accident.
My first thought was a self hosted black box type device. But I didn't see a GPS option listed. Sounds like it would be really useful as a vehicle monitor as well. Could catch issues and provide logs.
The device might not have GPS, but your vehicle might. It's a matter of what info your vehicle has available, and if you're able to interpret it (i.e., if you have the network spec available). Lots of possibilities either way.
I have a friend who set things up to calculate gas mileage, and used it to get into better driving habits.
