ha-extron

Home Assistant integration for Extron switchers and audio processors. It uses our pyextron library under the hood.

Supported devices

• SSP 200 surround sound processors
• SW HD 4K PLUS Series switchers

Requirements

Devices must have Telnet access enabled.

Features

Not every single feature can be controlled, only the basics:

• Media player support
  • Source selection
  • Volume control (SSP 200 only)
• Reboot button
• Temperature sensor (SSP 200 only)

The communication is done using Python's asyncio and requires no external libraries.

Caveats

• SSP 200 surround sound processors seem to stop responding properly (both to commands and to physical interactions like button presses) after some time, requiring a reboot

Development

Developing the integration and testing it locally in Home Assistant are two separate tasks.

For development, create a virtual environment (either manually or in an IDE like PyCharm), then install the dependencies using pip install ..

Running the integration involves setting up a Home Assistant development environment and making the integration available to it:

1. Clone this repository
2. Set up a Home Assistant development environment
3. Open devcontainer.json and add something like this to mounts:

"source=${localEnv:HOME}/Projects/ha-extron/custom_components/extron,target=${containerWorkspaceFolder}/config/custom_components/extron,type=bind",

Repeat this for any other integrations you want to make available in your local Home Assistant environment.

4. Start the development environment and browse to http://localhost:8123. If you go to Settings -> Integrations, you should be able to see your custom integrations listed

Tests

python3 -m unittest discover -s tests/ -v

Making a new release

1. Update the version number in manifest.json and pyproject.toml
2. Tag the release
3. Make a GitHub release

The new release should be picked up by HACS momentarily.
