Yes, well spotted! I used the snevl PI for a while until I moved to HS3 last year. I now use Paul Huddlestone's PI which was done in consultation with snevl.
actually, I want to track the car more than my phone - and the power drain as a percentage of the car battery to do so accurately is negligible whereas it's a heavy drain on an iPhone I found.
i am starting to think what an interface of HS to a model S might offer..... Any thoughts?
I've been using a basic windows form app I created. I use the tools here hjespers/teslams · GitHub (basically the streaming.js) which puts location and all telemetry data into a mongo database. This data is up to the second and incredibly accurate. It extracts the location data from a mongo database and puts it I to snevl's PI. So I just poll the database every 3 seconds and it tracks me. I guess we could find out from Huddlestone whether he could incorporate it as I was thinking of moving to HS3 but don't want to lose this functionality. My wife doesn't tease me anymore...
