Library implementing ZHA for Home Assistant

Zigbee Home Automation (ZHA)

ZHA is a versatile and hardware-independent Zigbee gateway implementation, designed to replace proprietary Zigbee gateways, bridges, hubs, and controllers. With ZHA, you can create a unified Zigbee network, allowing you to easily pair and connect a wide range of Zigbee-based devices for home automation and lighting.

Key Features

• Hardware Independence: ZHA is not tied to any specific hardware, giving you the freedom to choose the Zigbee radio that best suits your needs.
• Compatibility: ZHA supports a vast array of Zigbee-based devices, ensuring seamless integration with popular home automation and lighting solutions.
• Unified Zigbee Network: By utilizing ZHA, you can establish a single Zigbee network, simplifying device management and enhancing interoperability.
• Low-Bandwidth Communication: Zigbee operates on a low-bandwidth communication protocol, utilizing small, low-power digital radios to connect devices within local Zigbee wireless private area networks.

Getting Started With Development

To bootstrap a development environment for ZHA, follow these steps:

1. Clone the project from the zigpy organization:

   git clone https://github.com/zigpy/zha.git
   

2. Navigate to the script directory:

   cd zha/script
   

3. Run the setup script to install the necessary dependencies:

   ./setup
   

   The setup script sets up a virtual environment, installs necessary packages and dependencies, and configures pre-commit hooks for the project. It helps ensure a consistent and controlled development environment for the project, saving you time and effort.

   Script Overview

   The setup script in the zha/script directory performs the following actions:

   • curl -LsSf https://astral.sh/uv/install.sh | sh: This command uses curl to download a shell script from the specified URL (https://astral.sh/uv/install.sh) and then pipes it to the sh command to execute it. This script is responsible for installing a tool called "uv" (short for "universal virtualenv") which helps manage Python virtual environments.

   • uv venv venv: This command uses the "uv" tool to create a new Python virtual environment named "venv" in the current directory. A virtual environment is an isolated Python environment that allows you to install packages and dependencies specific to your project without affecting the global Python installation.

   • . venv/bin/activate: This command activates the newly created virtual environment. When a virtual environment is activated, any subsequent Python-related commands will use the Python interpreter and packages installed within that environment.

   • uv pip install -U pip setuptools pre-commit: This command uses the "uv" tool to upgrade the "pip" package manager, as well as install or upgrade the "setuptools" and "pre-commit" packages. "pip" is the default package manager for Python, "setuptools" is a library that facilitates packaging Python projects, and "pre-commit" is a tool for managing and enforcing pre-commit hooks in a Git repository.

   • uv pip install -r requirements_test.txt: This command uses the "uv" tool to install the Python packages listed in the "requirements_test.txt" file. This file typically contains a list of dependencies required for running tests in the project.

   • uv pip install -e .: This command uses the "uv" tool to install the project itself in editable mode. The dot (.) represents the current directory, so this command installs the project as a package in the virtual environment.

   • pre-commit install: This command installs Git pre-commit hooks for the project. Pre-commit hooks are scripts that run before each commit is made in a Git repository, allowing you to enforce certain checks or actions before committing changes.
