On Teslafi the Max and Average charge amps are displayed for each AC charge event. But if I download the corresponding CSV file I get different figures for the same event. This does not make sense.
Some changes may not have been carried over to the export script. Can you see if this appears to be correct now?
You may need to reset your charge records by clicking on 'Reset Charge Records' at the bottom of https://www.teslafi.com/charges.php but I don't believe it's necessary.
I am seeing the same thing. I'm seeing 12A on the website and 9A in the CSV. I've been having some home electrical issues so I've been keeping track both here and in the Tesla phone app. The Tesla app values agree with the TeslaFi web values rather than the CSV.
