Who is the primary developer of the Nissan Leaf portion of OVMS? Is there a way to contact this individual?
In general, for open source projects, it is best for users to communicate with the developers through the open community channels. After all, there are only a few of them, and a lot of us. It also gives more experienced users a chance to help by providing user-to-user support. If you really want to find more detailed info, head over to the github repo, and take a look at who is submitting code for the Leaf. Looks like most recent code change was an improved "wake up" message, commited in January. At least one Issue references this change, with a need to update the docs to indicate remote HVAC working on some cars that it did not before.
So, what are your questions?
