The `octoprint` binary sensor platform let you monitor if your 3D printer is printing or if there was a printing error.

<p class='note'>
You must have the [OctoPrint component](/components/octoprint/) configured to use this sensor.

To set it up, add the following information to your `configuration.yaml` file:

```yaml
binary_sensor:
  - platform: octoprint
    monitored_conditions:
      - Printing
      - Printing Error
```

Configuration variables:

- **monitored_conditions** array (*Required*): States to monitor.
  - **Printing**: State of the printer.
  - **Printing Error**: Error while printing.
- **name** (*Optional*): The name of the sensor. Default is 'OctoPrint'.
