Tesla Telemetry gateway for Apache Kafka

An implementation in Node.js of the streaming telemetry interface of Tesla Motors with output to Apache Kafka.

However, it is possible that use of this code may cause unexpected damage for which nobody but you are responsible.

Dependencies

Linux dependencies

• openssl
• libssl-dev
• libsasl2-dev
• libsasl2-modules
• C++ toolchain

macOS dependencies

• Apple Xcode command line tools (for the compiler)
• openssl installed via Brew (needed for root certs file in /usr/local/etc/openssl/cert.pem)
• Export CPPFLAGS=-I/usr/local/opt/openssl/include and LDFLAGS=-L/usr/local/opt/openssl/lib

Installation

To use this program you must download and install 'node' from http://nodejs.org

Install from npm on macOS

  brew install openssl
  export CPPFLAGS=-I/usr/local/opt/openssl/include
  export LDFLAGS=-L/usr/local/opt/openssl/lib
  sudo -E npm install -g teslams-rdkafka

Install from npm on Ubuntu

  sudo apt install nodejs-legacy
  sudo apt install openssl libssl-dev libsasl2-dev libsasl2-modules
  sudo npm install -g teslams-rdkafka

Install from npm on CentOS

  sudo yum install epel-release nodejs
  sudo yum install openssl openssl-devel cyrus-sasl-devel
  sudo npm install -g teslams-rdkafka

Uninstall

  sudo npm uninstall -g ccloud-node-console-client

Useage

The program requires -u and -p in order to specify the Tesla Motors user name and password to access your Model S. Or, you can instead create a json file in ~/.teslams/config.json and specify them once, in the following format:

{
	"username": "Your teslamotors.com username/email",
	"password": "Your teslamotors.com password"
}

In addition to putting your password as a command line option or a file, you can alternatively use the $TSLA_USERNAME and $TSLA_PASSWORD environment variables. These environment variable allow the execution of these apps in Heroku or other Platform-as-a-Service providers.

teslams-rdkafka - Capture and log real-time telemetry to Apache Kafka for analytics

An application which uses the TESLA HTTP Long Polling "STREAMING" API to get continuous telemetry from a Tesla Model S or Model X. A valid teslamotors.com login and password is required and must be provided on the command line options.

By default the output is a stream of JSON formatted messages published to a set of Kafka topics called "teslams", "teslams.climate_state", and "teslams.charge_state" with the keys being the id if the vehicle. The output topic prefix can be changed by using the --topic command line option.

To execute run:

teslams-rdkafka -u <username> -p <password> -U <kafka_username> -P <kafka_password> --kafka localhost:9092 --topic my_kafka_topic 

Usage: teslams-rdkafka -u <username> -p <password> -U <kafka_username> -P <kafka_password> [-sz]
        [--kafka localhost:9092] [--topic my_kafka_topic] [--ca_cert_loc /usr/local/etc/openssl/cert.pem]
        [--values <value list>] [--maxrpm <#num>] [--vehicle offset] [--naptime <#num_mins>]

Troubleshooting

If you see the following error when you run either console producer or consumer, it means you have not installed librdkafka correctly with the required SSL and SASL libraries. See install instructions for installing openssl and setting compiler flags.

Caught error: Error: Invalid value for configuration property "security.protocol"

If the ccloud-console-producer or ccloud-console-consumer immediately exits to the shell prompt you are likely missing the Root CA Certificates. See the location of these certs (below) and add the correct -S flag pointing the the location of the certs on your operating system.

The default SSL Certificate location is /usr/local/etc/openssl/cert.pem which works on macOS but every flavor of Linux puts root certificates in different places.

Ubuntu/Debian/Raspbian: /etc/ssl/certs CentOS/RedHat: /etc/pki/tls/cert.pem macOS: /usr/local/etc/openssl/cert.pem (from brew install openssl)

For Ubuntu add the -C /etc/ssl/certs flag to specify your certificate location:

teslams-rdkafka -u [email protected] -p MyTeslaPassword -U $CCLOUD_SASL_USERNAME -P $CCLOUD_SASL_PASSWORD -k $CCLOUD_BROKERS -C /etc/ssl/certs

For CentOS/RedHat add the -C /etc/pki/tls/cert.pem flag to specify your certificate location:

teslams-rdkafka -u [email protected] -p MyTeslaPassword -U $CCLOUD_SASL_USERNAME -P $CCLOUD_SASL_PASSWORD -k $CCLOUD_BROKERS -C /etc/pki/tls/cert.pem
