websocket_api integration set up a WebSocket API and allows one to interact with a Home Assistant instance that is running headless. This integration depends on the
# Example configuration.yaml entry websocket_api:
For details to use the WebSocket API, please refer to the WebSocket API documentation .
The WebSocket API provides a sensor that will keep track of the number of currently connected clients. You can add it by adding the following to your configuration:
# Example configuration.yaml entry sensor: - platform: websocket_api
This will create a sensor called
sensor.connected_clients whose value is the total number of connected clients.
