Z-Wave USB stick

Communicates with devices via the Z-Wave radio and stores device pairing.

Z-Wave JS

Represents the USB stick serial protocol as devices.

Z-Wave JS Server

Forward the state of Z-Wave JS over a WebSocket connection.

Z-Wave JS Server Python

Consumes the WebSocket connection and makes the Z-Wave JS state available in Python.

Z-Wave JS integration

Represents Z-Wave devices in Home Assistant and allows control.

Home Assistant

Best home automation platform in the world.

Running Z-Wave JS Server

alt text

Z-Wave JS Server can be run as a standalone Node app.

It can also run as part of Z-Wave JS 2 MQTT, which is also a standalone Node app.

Both apps are available as Home Assistant add-ons. There are also Docker containers etc.
