Tesla API v3.9.1

Haven’t had time until now to explore on what is new as Tesla continues to push updates. The latest version as of this post is v3.9.1 which is what there I decompiled and when compared to the earlier version (I had posted (v3.8.2), there three new REST API’s outlined below.

Service data from the car – not sure what exactly does this will. Need to try it.

   "VEHICLE_SERVICE_DATA": {
    "TYPE": "GET",
    "URI": "api/1/vehicles/{vehicle_id}/service_data",
    "AUTH": true
  }

Now, when I call that, I get a 200OK response (see below), so it is accepting the request, and that includes the bearer code in the header as expected. I don’t see anything interesting back, but that could be because my car is not in service. Maybe someone who has their vehicle in the service center can try and validate this.

{
    "response": {}
}

The next new API is a POST, for reports; and calling this just sends a 200OK back, but I don’t know what it is for. It seems very similar to the SEND_LOG method.

"SEND_REPORT": {
    "TYPE": "POST",
    "URI": "api/1/reports",
    "AUTH": true
  }

The next two set of APIs seem quite interesting and related t AutoPilot upgrade. It might be that these could be in app purchases – checking the eligibility, and then allowing one to purchase. 

"UPGRADE_ELIGIBILITY": {
    "TYPE": "GET",
    "URI": "api/1/vehicles/{vehicle_id}/eligible_upgrades",
    "AUTH": true
  },
  "AUTOPILOT_UPGRADE_URL": {
    "TYPE": "GET",
    "URI": "api/1/vehicles/{vehicle_id}/purchase_url",
    "AUTH": true
  }

When I try and call the Purchase_URL, I get a HTTP 400, and seems like I am missing some parameters – other than the headers.

{
    "error": "bad_request",
    "error_description": "The data given to this server does not meet our criteria."
}

And calling the eligible_upgrades I get a ‘false’. Now I already have AutoPilot, so this might make sense. And given this seems to be a key-value pair, I am guessing there will be other things that Tesla would add over time to up-sell.

{
    "autopilot": false
}

The final new API is related to energy sites, and something I of course don’t have or have an interest, but sharing here if someone does care. 🙂

"CALENDAR_HISTORY_DATA": {
    "TYPE": "GET",
    "URI": "api/1/energy_sites/{site_id}/calendar_history",
    "AUTH": true
  }

I am not publishing the full API here as there aren’t significant changes. You of course can see the older post which has the details.

npm install blues – npm ERR! Error: Method Not Allowed

This is a output of a few frustrating hours (spanning over a few days – as and when I can get time), and finally got it fixed and working. Hopefully it might help someone who is also dealing with npm blues.

When NodeJS and npm works, its awesome. But when it borks, it is worst than my code or so it seems :).

Been playing with a few things and wanting to get a dashboard going with Grafana (and InfluxBD as a time-series DB). But some of the installation was failing and for the life of me, could not figure out why and how. Clean image install and downgrading to the previous stable version also didn’t help.

One example of npm failing miserably was the “Error: Method not Allowed” which is not very helpful. Here is an example of what I was seeing:

root@pi-server:/var/lib/grafana/plugins/grafana-trackmap-panel# npm install

Again, like I said not very helpful. But I finally got to be able to fix it and move on. And here is what worked for me, and it seems like in the OS image, there was a corrupted files, at some level. In most cases you need root access.

Step 1: – Remove and clean up NodeJS.

sudo apt-get remove nodejs nodejs-legacy nodered

Step 2: Get the latest stable source.

curl -sL https://deb.nodesource.com/setup_$NODE_STABLE_BRANCH | sudo -E bash -
sudo apt-get install -y nodejs
npm install -g npm@latest\

I also noticed sometimes the commands above don’t work. If that is the case then then try the following, to get the latest.

curl -sL https://deb.nodesource.com/setup_9.x | sudo -E bash -
sudo apt-get install -y nodejs
npm install -g npm@latest

And based on your dependencies, v9 might not work and you need v8 then you change the first line as following Or for the latest:

curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install -y nodejs
npm install -g npm@latest

And finally in the end install and start.

npm install &amp;&amp; npm start

And if you do need to check for the update and get the latest, then try:

sudo npm install -g npm@latest
