The `rflink` component support devices that use [RFLink gateway firmware](http://www.nemcon.nl/blog2/), for example the [Nodo RFLink Gateway](https://www.nodo-shop.nl/nl/21-rflink-gateway). RFLink gateway is an Arduino firmware that allows two-way communication with a multitude of RF wireless devices using cheap hardware (Arduino + transceiver).

First you have to set up your [rflink hub](/components/rflink/).

After configuring the RFLink hub sensors will be automatically discovered and added.

New/unknown sensors can be assigned to a default group automatically by specifying the `new_devices_group` option with a group name. If the group doesn't exist it will be created.

For example:

```yaml
# Example configuration.yaml entry
sensor:
  platform: rflink
  new_devices_group: "New RFLink Sensors"
```

RFLink sensor ID's are composed of: protocol, id and type (optional). For example: `alectov1_0334_temp`. Some sensors emit multiple types of data. Each will be created as its own

Once the ID of a sensor is known it can be used to configure the sensor in HA, for example to add it to a different group, hide it or configure a nice name.

Assigning name to a sensor:

```yaml
# Example configuration.yaml entry
sensor:
  platform: rflink
  devices:
    # assign name to a sensor
    alectov1_0334_temp:
      name: Temperature Outside
```

Configuration variables:

- **devices**  (*Optional*): A list of devices with their name to use in the frontend.
- **new_devices_group** (*Optional*): Create group to add new/unknown devices to.

Device configuration variables:

- **name** (*Optional*): Name for the device, defaults to RFLink ID.
- **sensor_type** (*Required*): Override automatically detected type of sensor.
- **unit_of_measurement** (*Optional*): Override automatically detected unit of sensor.
- **aliasses** (*Optional*): Alternative RFLink ID's this device is known by.

### {% linkable_title Hiding/ignoring sensors %}

Sensors are added automatically when the RFLink gateway intercepts a wireless command in the ether. To prevent cluttering the frontend use any of these methods:

- Configure a `new_devices_group` for sensors and optionally add it to a different `view`.
- Hide unwanted devices using [customizations](/getting-started/customizing-devices/)
- [Ignore devices on a platform level](/components/rflink/#ignoring-devices)
