# DeviceHub, Devices

Manage industrial devices configured in Litmus Edge DeviceHub: drivers, device records, and connection status.

| Tool                                | Description                                                                                                           |
| ----------------------------------- | --------------------------------------------------------------------------------------------------------------------- |
| `get_litmusedge_driver_list`        | List supported Litmus Edge drivers (e.g., ModbusTCP, OPCUA, BACnet).                                                  |
| `get_devicehub_devices`             | List all configured DeviceHub devices with connection settings and status.                                            |
| `create_devicehub_device`           | Create a new device with a specified driver and default configuration.                                                |
| `get_device_connection_status` `**` | Check whether devices are actively publishing data via InfluxDB heartbeat. Reports `connected` / `stale` / `no_data`. |

## When to use which

- **Onboarding a new asset:** `get_litmusedge_driver_list` -> `create_devicehub_device`.
- **Inventory / triage:** `get_devicehub_devices` for the configured set; `get_device_connection_status` for the live ingest state.
- **"Is data flowing?":** `get_device_connection_status`. The "connected" determination comes from InfluxDB recency of the device's tags, so the `INFLUX_*` headers must be set.

## Requirements

- `EDGE_URL`, `EDGE_API_CLIENT_ID`, `EDGE_API_CLIENT_SECRET` for all tools.
- `INFLUX_HOST`, `INFLUX_PORT`, `INFLUX_DB_NAME`, `INFLUX_USERNAME`, `INFLUX_PASSWORD` additionally for `get_device_connection_status`.
