This assumes that all labs use PoE for power control, right?. Maybe it would be nice to have a "Power Control Options" subsection that mentions more approaches. I'm thinking something like this:

| * PoE switch (i.e. **Zyxel GS1900-8HP**) | |
| * PoE Splitter (12v, 5v, etc.) | |
| * Devices-Under-Test (DUTs) | |
| * Some cables | |
| * A guest wifi | |
| ### Requirements | |
| #### Core Components (All Labs) | |
| - Coordinator/Exporter host (e.g., Raspberry Pi 5, ThinkPad, etc.) | |
| - Internet access for coordinator (wired or via guest WiFi network) | |
| - Network switch (managed recommended) | |
| - USB-to-serial adapters (one per DUT) | |
| - Devices-Under-Test (DUTs) | |
| - Ethernet cables | |
| #### Power Control Options (multiple approaches depending on your preferences) | |
| **Option A: PoE-based (Recommended for simplicity)** | |
| - PoE-capable managed switch (e.g., Zyxel GS1900-8HP) | |
| - PoE splitters matching DUT voltage requirements (5V, 12V, etc.) | |
| - Labgrid will use `NetworkPowerPort` resource | |
| **Option B: Relay-based (Lower cost, more flexible)** | |
| - Arduino or similar microcontroller (software interface required) | |
| - Relay module (one channel per DUT) | |
| - USB cable (controller to coordinator) | |
| - PDUDaemon software | |
| - Labgrid will use `PDUDaemonPort` resource | |
| **Option C: GPIO-based (Raspberry Pi only)** | |
| - GPIO-controlled relay board | |
| - Labgrid will use GPIO drivers |

| The controller should be setup via Ansible, which install `labgrid` as well as |

Hi @aparcar ! I have a question that came to mind while looking at tihis diagram. Each lab has a "Lab Coordinator." How are these coordinators different from the Global Coordinator / what are they needed for? My guess is that the green lab coordinators are only involved in local testing of each lab. Otherwise, the interaction is directly between the global coordinator and each lab's exporter.. is this right?
