Description

This project connects bluetooth devices in a plejd mesh to an MQTT broker. Devices are discovered automatically by Home Assistant.

The project currently supports:

• Plejd Light
• Plejd Device Trigger
• Plejd Switch (untested)

Not supported currently:

• Plejd Sensor
• Plejd Scenes

Getting started

This section provides step-by-step instructions on how to set up and run the program on your local machine.

The project is intended to run as a docker container, but can also be run locally.

Setting Up and Running the Program Locally

This section provides step-by-step instructions on how to set up and run the program on your local machine.

Prerequisites

Ensure that you have the following dependencies installed on your system:

• python: The programming language used for this project.
• poetry: A tool for dependency management in Python.
• bluetooth: A library to work with Bluetooth.
• bluez: Official Linux Bluetooth protocol stack.

Refer to the Dockerfile in the project root for specific versions of these dependencies.

Installing Python Dependencies

After installing the prerequisites, you can install the Python dependencies for the project. Run the following command in your terminal:

poetry install

Activating the Virtual Environment

Next, spawn a new virtual shell using the following command: Start the program using:

poetry shell

This command activates the virtual environment, isolating your project dependencies from other Python projects.

Running the program

Finally, you can start the program using the following command:

python -m plejd_mqtt_ha

This command runs the plejd_mqtt_ha module as a script, starting the program.

Setting Up and Running as a Docker Container

This section provides instructions on how to build and run the program as a Docker container. Docker must be installed on your host machine to follow these steps.

Building the Docker Image

First, build a Docker image for the program. This creates a reusable image that contains the program and all its dependencies. Run the following command in your terminal:

docker build . -t plejd

This command builds a Docker image from the Dockerfile in the current directory, and tags the image with the name plejd

Running the Docker Container

After building the image, you can create and start a Docker container from it. For the settings and cache files to persist, it's necessary to mount a configuration directory. At present, the container must operate in privileged mode and with host network capabilities. Before initiating the container, you must halt the Bluetooth service:

service bluetooth stop

Once the service is halted, execute the following command in your terminal:

docker run -v ./data/:/data/ --rm --net=host --privileged -it plejd

This command starts a new Docker container from the plejd image. The program inside the container will start running immediately.

Running with Docker Compose

As an alternative to the docker run command, you can use Docker Compose to manage your application.

To start the application with Docker Compose, run:

docker-compose up

This command will start a new Docker container from the plejd image, just like the docker run command. The program inside the container will start running immediately.

Configuration
