Explain consumption difference between TeslaFi's "Drive Details" and car's display

MarcMMueller 1 year ago updated by Whiteblaze 3 weeks ago 6

Yesterday I made a 35 minutes drive to home. After that, my Tesla's display showed up 181 Wh/km. But TeslaFi's "Drive Details" gave me 241 Wh/km for this route. How this difference can be explained? I feel much better, when I'm able to beat 200 Wh/km (~322 Wh/mile) with my X90D ;-) Thanks (I'm new to TeslaFi)

I would also like to see the usage as reported by the car in the log.


I've been seeing TeslaFi reporting high as well.

Same here. Does TeslaFi account for accessories that Tesla may not be?

I just noticed this as well. Yesterday, TeslaFi reported a 128 mile round trip at 428 Wh/mi while my car's display showed 319. For the return trip, TeslaFi reported 431 Wh/mi versus 335 displayed by my car.

Was there an answer given to anyone for this?

Actually yes, I received this response by email. Forgot to repost here, sorry:


The wh/mi is not provided by the Tesla API and has to be calculated. You can adjust this calculation if it appears to be off in settings->account->vehicle->kWh & Wh/m(km) Factor:. In this case you could try .777 (335/431).
