Telemetry Development

Running Telemetry

With Docker

Telemetry can be run simply using the command:

./telemetry.sh dev -b -m

The usage for this script is:

./telemetry.sh <pnpm_script> [OPTIONS]

Options:
-h, --help              Display this help message
-b, --build             Build the docker image before running the container
-m, --with-mqtt-broker  Run the MQTT broker along with the container

Without Docker

Alternatively, if you want to run without Docker you can follow these steps to install everything required:

• Install node
• Install pnpm:

npm install -g pnpm

• You can now run Telemetry:

cd telemetry
pnpm install
pnpm build
pnpm dev

To run the full Telemetry system, you will also need InfluxDB and an MQTT broker running locally.

• To install InfluxDB, follow the instructions https://www.influxdata.com/downloads/.
• We recommend Mosquitto as an MQTT broker, which can be downloaded from https://mosquitto.org/download/.

The above tools are also available as Docker images: mosquitto, influxdb.

For Mosquitto, the following config file mosquitto.conf is needed:

# mqtt protocol
listener 1883
protocol mqtt

# websockets protocol (for GUI)
listener 8080
protocol websockets
allow_anonymous true

To use this config file, run mosquitto with the following argument -c <path to moquitto.conf>.

Development Environment

We highly recommend using https://code.visualstudio.com/ as your code editor when working on Telemetry. The following VSCode extensions are required:

• TailwindCSS IntelliSense - gives you autocompletion for Tailwind classes
• Prettier - code formatter (you can enable this to run on save and never think about formatting again)
• ESLint - shows ESLint errors in VSCode

And the following are recommended:

• Pretty TypeScript Errors - formats TypeScript errors to make them easier to read and understand
• PostCSS Language Support - gets rid of TailwindCSS errors in CSS files
• JSDoc Markdown Highlighting
• Import Cost - displays the size of imported packages
• Error Lens - inline error messages
• DotENV - syntax highlighting in .env files
• GitLens - shows git history in VSCode

Optional

MQTTX

If you want a GUI for sending and subscribing to custom MQTT messages, we recommend MQTTX which can be installed from https://mqttx.app/.
