The [MySensors](https://www.mysensors.org) project combines Arduino boards with NRF24L01 radio boards to build sensor networks.

Integrate your Serial MYSensors Gateway by adding the following to your `configuration.yaml` file:

```yaml
# Example configuration.yaml entry
sensor:
  platform: mysensors
  port: /dev/ttyACM0
```

Configuration variables:

- **port** (*Required*): The port where your board is connected to your Home Assistant host.
- **debug** (*Optional*): Enable or disable verbose debug logging.
- **persistence** (*Optional*): Enable or disable local persistence of sensor information. If this is disabled, then each sensor will need to send presentation messages after Home Assistant starts.
- **persistence_file** (*Optional*): Path to a file to save sensor information. The file extension determines the file type. Currently supported file types are 'pickle' and 'json'.
- **version** (*Optional*): Specifies the MySensors protocol version to use (ex. 1.4, 1.5).

If you are using an original Arduino the port will be named `ttyACM*`. The exact number can be determined with the command shown below.

```bash
ls /dev/ttyACM*
```
