I know that neither battery_range or ideal_battery_range are based on dynamic wH/mile values.

That is what I was assuming, that only "est_battery_range" is a dynamic value. I just verified it with the data in my car and "est_battery_range" is what is presented in the UI as "Projected Range". To be specific, the API returns the value of the last 50 kilometers. Not sure that if I select 10km in the UI is that changes the values in the API (yet..).

wk057 posted the Wh/mile values that are used for the rated range calculation over here:

That is using 285 Wh/Mile, or 177.09Wh/kilometer for "rated" which is "battery_range" in the API results. I'm getting the following results when converting and extrapolating for my S100D:

Code:

Current ranges:
        rated: 381.48km, 237.04m (battery_range)
        ideal: 306.37km, 190.37m
    estimated: 222.12km, 138.02m

Max ranges:
        rated: 625.37km, 388.59m (battery_range)
        ideal: 502.25km, 312.08m
    estimated: 364.13km, 226.26m

Consumption:
        rated: 177.09Wh/km, 285.00Wh/m (battery_range)
        ideal: 220.51Wh/km, 354.87Wh/m
    estimated: 304.14Wh/km, 489.47Wh/m

Pack capacity (SoC: 61%):
      current:  67.56kWh
          max: 110.75kWh

As this extrapolates to 110.75kW I don't think 285Wh/Mile for rated is the correct value.

I've once heard that "rated" in the US is different for the EU.

Who can confirm the API values for US cars from the API?

It makes sense that that rated would mean something different in the EU, since here in the US, it's based on the rating from a US government agency. That would explain why your rated range is higher than ideal range, which is the opposite for US cars. (For instance, right now, the API shows 148.07, 80.6, 168.39 for battery_range, est_battery_range, ideal_battery_range for my car.)

Also, it looks like wk057's numbers don't cover the non-performance 100D.

Here's someone saying "rated miles in UK = ideal U.S. miles": Calculate usable battery capacity based on rated miles values

(UK is still in the EU, last I checked!)

I captures the values from the UI and the API and compared them:

Code:

User interface:
    soc:      55%
    typical: 276km   => 171.49m
    rated:   343m    => 213.13m

Energy display (average):
    10km: 198Wh/km, 271km (168.39km)
    25km: 251Wh/km, 214km (132.97km)
    50km: 261Wh/km, 205km (127.38km)

API: (via Teslafi.com account info)
    battery_level:        55%
    battery_range:       213.21m  => 343.12km (rated in GUI)
    est_battery_range:   127.59m  => 205.33km
    ideal_battery_range: 171.23m  => 168.39km

This means that: (foratleast EU cars)

- Typical in the UI is mapped to "ideal_battery_range" in the API
- Rated in the UI is mapped to "battery_range" in the API

Which makes it a bit strange that "battery_range" from the API isn't used in the EU User Interface. Maybe that is different in US cars.

More 'realistic' range:
* 'rated' in USA &
* 'typical' in non-USA

'Constant value' range:
* 'ideal' in USA &
* 'rated' in non-USA

This is great thanks for sharing!

Not really, I would like to actually know if the values reported with the Tesla API are different between US and EU. I already know that both "est_battery_range" and "ideal_battery_range" use fixed consumption rates.

Its just that I don't think the consumption rate of 160Wh/km for my S100D is correct as that extrapolates to a usable pack capacity of 99.86kWh.

Is someone able to share API output from a US S100D ?

Does anyone know the endpoint for the Sentry mode?

Thank you! Do you also know what the body of the http should be to turn it on/off?

Unfortunately no. My car hasn't gotten the sentry mode update yet. When I send a request with a blank body I get a 500 internal server error with this response:

Code:

{
    "error": "system",
    "error_description": "An unknown error has occurred."
}

but when I send a request with anything in the body like:

Code:

{
    on: false
}

I get a 404 not found error with this response:

Code:

{
    "response": null,
    "error": "`` for txid `(txid here)`",
    "error_description": ""
}

I hope I can get this update soon...

I can confirm that the above works. Thanks!

i have a question to the return value of "power" in the stream:
is the unit kW or horsepower?
i mean it is kW.

"https://streaming.vn.teslamotors.com/stream/" + str(Tesla_vehicle_id) + "/?values=speed,odometer,soc,elevation,est_heading,est_lat,est_lng,power,shift_state,est_range"

Hi all, what is the proper way to turn on climate in the car to a set temperature, such as LO/60F or 70F? Would you run auto_conditioning_start, then set_temps for both passenger/driver sides, or the reverse order? Thanks.

I'm seeing 502 Bad Gateway for the streaming API, today. (The main API continues to work.) Anybody else seeing this? Doesn't seem like something that would be on my end, but just want to make sure.

I have a data acquisition program running that logged some server-side errors (Request Timeout and Internal Server Error) today around 0830 and 1530 PDT, but those were using the main API, not the streaming API.

Bruce.

Now I'm seeing many many failures from the main API (error code 500) since 9:42 PM PST yesterday. Many more failures than successes. (For each polling interval, my script tries a few times before giving up, and it usually gets through on one of the retries.)

And the streaming API is still returning 502 consistently. Is anybody else monitoring the streaming API these days?

Dazboj · Mar 9, 2019

Streaming API is working fine for me this morning at 10:00 GMT

Seeing the same streaming errors. Haven't been able to stream since 3/7 in the am.

This is pretty much what I'm getting, over and over:

9 Mar 11:03:10 - Unexpected problem with request:
    Response status code = 502  Error code = null

9 Mar 11:23:22 - 4 of 6 Stream requests since 1552159362263
