# PowerBoard

## Overview

You can control and monitor the Power Board from the command line using the `pocs power` command. 

For example:

```bash
# Display the status for each power channel (relay)
pocs power status

# Turn off the fans.
pocs power off fans

# Turn on fans by relay index.
pocs power on RELAY_2

# See the current readings for all power channels.
pocs power readings
```

## Commands

### `status`

Get the status of the relays.

```
(conda-pocs)  panoptes@panoptes  pocs power status
[RELAY_0] weather_station..... ON
[RELAY_1] unused1............. OFF
[RELAY_2] fans................ ON
[RELAY_3] unused3............. ON
[RELAY_4] mount............... ON
(conda-pocs)  panoptes@panoptes  
```

### `off/on`

Turn on or off the relay.

```
(conda-pocs)  panoptes@panoptes  pocs power off fans
{'relay': 'fans', 'command': 'turn_off'}

(conda-pocs)  panoptes@panoptes  pocs power status
[RELAY_0] weather_station..... ON
[RELAY_1] unused1............. OFF
[RELAY_2] fans................ OFF
[RELAY_3] unused3............. ON
[RELAY_4] mount............... ON

(conda-pocs)  panoptes@panoptes   pocs power on fans
{'relay': 'fans', 'command': 'turn_on'}

(conda-pocs)  panoptes@panoptes  pocs power status
[RELAY_0] weather_station..... ON
[RELAY_1] unused1............. OFF
[RELAY_2] fans................ ON
[RELAY_3] unused3............. ON
[RELAY_4] mount............... ON
```

### `control`

A different way to control the relays.

```
(conda-pocs)  panoptes@panoptes  pocs power control --relay fans --command turn_off
{'relay': 'fans', 'command': 'turn_off'}
```

### `readings`

Shows a simple bar plot of the most recent power usage statistics for each relay. Probably not actually useful.

```
(conda-pocs)  panoptes@panoptes  pocs power readings
ac_ok............... ▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄ [1]

```

### `restart`

Restart the power (`supervisorctrl`) service. Use if getting errors with the other commands.

```
(conda-pocs)  panoptes@panoptes  pocs power restart
```

## Configuration

The configuration for the power board is stored under the `environment.power` key:

```
(conda-pocs)  panoptes@panoptes  pocs config get environment.power
{
    'arduino_board_name': 'power_board',
    'mean_interval': 5,
    'name': 'Trucker Power',
    'port': '/dev/ttyACM0',
    'record_interval': 60,
    'relays': {
        'RELAY_0': {'default_state': 'on', 'label': 'weather_station'},
        'RELAY_1': {'default_state': 'off', 'label': 'unused1'},
        'RELAY_2': {'default_state': 'on', 'label': 'fans'},
        'RELAY_3': {'default_state': 'off', 'label': 'unused3'},
        'RELAY_4': {'default_state': 'on', 'label': 'mount'}
    }
}
```
