# Electrical: controls and readings

## Access through MCP

Use `list_groups` to discover cockpit groups. `list_readings` lists their readable values; `read_group` returns the current values. Available controls are listed below with their `cockpit_*` tool.

### Electrical

Read this group with `read_group`:

```json theme={null}
{
  "group": "electrical"
}
```

#### Controls

Call `cockpit_electrical` with `action` and, where indicated, `value` or `text`.

| Control | action | Input |
| - | - | - |
| Battery | `battery` | select; 0=off, 1=on |
| Standby power | `standby-power` | select; -1=bat, 0=off, 1=auto |
| Ground power cart | `ground-power-cart` | select; 0=disconnected, 1=connected |
| GPU | `gpu` | select; 0=off, 1=on |
| Generator 1 | `generator-1` | select; 0=off, 1=on |
| Generator 2 | `generator-2` | select; 0=off, 1=on |
| APU generator 1 | `apu-generator-1` | select; 0=off, 1=on |
| APU generator 2 | `apu-generator-2` | select; 0=off, 1=on |
| AC power panel | `ac-power-panel` | select; 0=position 0, 1=position 1, 2=position 2, 3=position 3, 4=position 4, 5=position 5, 6=position 6 |
| DC power panel | `dc-power-panel` | select; 0=position 0, 1=position 1, 2=position 2, 3=position 3, 4=position 4, 5=position 5, 6=position 6 |

#### Readings

Call `read_reading` with `reading_id` from this table, or read all values with `read_group`.
