Raw

Toyota-data-feeder

This is a demo application which playbacks included .csv file indefinitely, and sends it as mqtt message to mqtt broker. Included csv contains raw data dump with mapped signals and units of Toyota RAV4 Hybrid car.

Do note that for the first 5 minutes there is not much happening. This is because the driver of the car was doing something else than driving. Log file takes 13 minutes to playback.

git clone https://github.com/smaddis/toyota-data-feeder.git

Dev environment

Python 3.9

If you want to test application locally, it is recommended to setup Python virtualenv first.

python3 -m venv .venv
source .venv/bin/Activate
pip install -r requirements.txt

Set env variables

export MQTT_URL=localhost MQTT_PORT=8883 CLIENT_ID=foo

  • MQTT_PORT Mqtt broker port
