The `octoprint` sensor platform let you monitor various states of your 3D printer and its print jobs.
<p class='note'>
You must have the [OctoPrint component](/components/octoprint/) configured to use this sensor.
</p>
To set it up, add the following information to your `configuration.yaml` file:
```yaml
# Example configuration.yaml entry
sensor:
- platform: octoprint
name: OctoPrint
monitored_conditions:
- Current State
- Temperatures
- Job Percentage
```
Configuration variables:
- **name** (*Optional*): The name of the sensor. Default is 'OctoPrint'.
- **monitored_conditions** array (*Required*): States to monitor.
- **Current State**: Text of current state)
- **Temperatures**: Temperatures of all available tools, eg. `print`, `head`, `print bed`, etc. These will be displayed as `tool0`, `tool1`, or `toolN` please refer to your OctoPrint frontend to associate the tool number with an actual device.
- **Job Percentage**: Percentage of the job.
<p class='note'>
If you are tracking temperature it is recommended to set `bed` and/or `number_of_tools` in your octoprint configuration. This will allow the octoprint sensors to load if the printer is offline during Home Assistant startup.
