Developing with Visual Studio Code + devcontainer
The easiest way to get started with custom integration development is to use Visual Studio Code with devcontainers. This approach will create a preconfigured development environment with all the tools you need.
In the container you will have a dedicated Home Assistant core instance running with your custom component code. You can configure this instance by updating the ./config/configuration.yaml file.
Prerequisites
- git
- Docker
- For Linux, macOS, or Windows 10 Pro/Enterprise/Education use the current release version of Docker
- Windows 10 Home requires WSL 2 and the current Edge version of Docker Desktop (see instructions here). This can also be used for Windows Pro/Enterprise/Education.
- Visual Studio code
- Remote - Containers (VSC Extension)

Getting started:
- Fork the repository.
- Clone the repository to your computer.
- Open the repository using Visual Studio code.
When you open this repository with Visual Studio code you are asked to "Reopen in Container", this will start the build of the container.
If you don't see this notification, open the command palette and select Remote-Containers: Reopen Folder in Container.
Step by Step debugging
With the development container, you can test your custom component in Home Assistant with step by step debugging.
Launch the debugger with the existing debugging configuration Home Assistant.
