I've made a data recorder that is hosted, which mean you do not have to run any application on your computer. I have 6 Tesla Model S being monitored and it seem to be working well so far (1 in USA right now and 5 in Canada). I've just finished adding imperial unit for the result being display (was metric only before), so It time to get a few more tester on board. Just send me a private message on the forum and I'll send you a link so you can register. Currently it will store every minute your climate information and charging (It will group charging by session). It also log your real time GPS data grouped by trip. You can see your Wh/miles for every trip you made. I've added the head wind estimator also which give much better gps coordinate than the one from the browser only. So if Tesla tomorrow announcement doesn't include a better way to estimate Wh/mile usage by checking weather information, then with more data on different route, I'll be able to do it You can set geo location where your car climate remain on even when you get out of the car. Great for when you are leaving or picking up the kid at the kindergarder and you don't want your car to get cold (or warm) on short stop. There is a bunch of other feature that will be added, and I'm open to suggestions. I'm hoping to have enough user at some point to do some 'competition' of who have the lowest Wh/miles for example... But for the moment I'm focusing more getting interesting data for the car owner to monitor. The UI is not pretty but does the job... Lot of things to improve, but what is important is the logged data, everything else can be done latter on. So like I said, just PM me that your interested and I'll msg you the link. PS... It useless if you don't have a Tesla Model S of course !
