let's say I am adding a car..

then new car is added, I flip over to logging for the new car. And I see things updating going forward.

If I flip back will I see the history of the old car?

Or is it all put together as one big datablob and it just starts logging with the new source but to the same destination?

Would be nice to have the ability to see temperature efficiency ratings where you can check climate control on/off/both so you can compare how much efficiency you're losing due to climate control. Possible to add temp range as well if set to on.

When you have more than one car and get trip and charge emails, there’s no way to tell them apart that I can see (besides knowing things like odometer levels). Am I missing something or could an option be added to have the car name on the emails. 

Even in the subject would do, I think.  

This graph is very useful to me.

However, as an electrical engineer, I would be very happy to know how the calculation is processed.

For instance, if I drive using lot of heating / air conditioning, defrost, seat heaters, of course I will consume more energy than when all theses are off.

So, the battery will drain more or less quickly, while same distance has been accomplished.

It doesn't mean the battery is degraded.

So I guess the calculation is based on more specific data that Teslafi can exploit from what you gather from official Tesla data base.

Could you explain this for those who like technical details?

Thank you very much in advance!

This (battery degradation report tweaking) is a great solution, James.  Works like a charm on my checkered charging past!

Please post questions or issues here.

Is there a way to split drives? I can see a merge button, but not a split button. According to these posts, there seems to be a way, but either it was removed or I just can't find it:

What if you threw a sparkline next to each software version that showed the number of installs per hour for the last 24 or 48 hours? That would potentially answer the question I've always had when looking at these stats: how fast is this version rolling out compared to others?

It would be nice to have a column in the charging tables that displays the percentage of total kwh charged at this location. Ie. Home = 48% of all charged kwh added at this location.  Also a general percentage for the categories, like "CHAdeMO = 22% of all kWh charged at CHAdeMO-chargers". This data is available, but has to be calculated manually for now. 

A pie-chart of the categories at the right side of the screen would also be nice. Should be divided into "Home AC", "Other AC", "CHAdeMO" and "Supercharger".
