Unfortunately for the 2023 Nissan Leaf has a CAN gateway module. Basically, it's like a firewall or gateway to filter out CAN writing commands commands so you can't directly talk to the car with open tools through the OBD-II. Basically, it's a read-only port that's only when the car is powered on. Unfortunately a lot of cars are now starting to do this. I guess I'm gonna have to make a modified version of CAN tap cable for an unrestricted OBD-II port. :( https://docs.openvehicles.com/en/latest/components/vehicle_n...

I own a Hyundai Ioniq 5. There seems to be documentation for OVMS support: https://docs.openvehicles.com/en/latest/components/vehicle_h... but very little documentation for how to get up and running or even where to obtain hardware for my car. $350 plus a few bucks a month for a low data SIM is actually worth it for me for privacy, and Hyundai charges $100 a year for buggy software with less features. I hope this takes off.

Not a new project, but one that's relevant to a lot of recent discussions of privacy-invasive connected systems built into modern cars

I would think you could do this with a comma.ai device too.

The hardware is US$345. A little step for an odb bridge?
