+      icon: "fas fa-cloud-sun"
+```
+
+**Configuration Options:**
+
+- When `sensors` is provided, the service displays sensor readings with custom icons instead of the default version/entity information
+- `showUnits`: Controls whether to display units from Home Assistant (default: `true`)
+- `updateInterval`: How often to refresh sensor data in milliseconds (default: `30000`)
+- Sensor values are automatically formatted to 1 decimal place with units (when enabled)
+- Supports any numeric sensor type (temperature, humidity, power, etc.)
+- Falls back to original behavior if `sensors` is not configured
+
 To create an API token on HomeAssistant, follow the [official documentation here](https://developers.home-assistant.io/docs/auth_api/#long-lived-access-token).  
 To enable cors on HomeAssistant, edit your `configuration.yml` and add the IP of Homer to `https: cors_allowed_origins`
