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.
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:
alectov1_0334_temp:
name: Temperature Outside
```
Configuration variables:
- **automatic_add** (*Optional*): Automatically add new/unconfigured devices to HA if detected (default: True).
- **devices** (*Optional*): A list of devices with their name to use in the frontend.
Device configuration variables:
- **name** (*Optional*): Name for the device, defaults to RFLink ID.
- **sensor_type** (*Required*): Override automatically detected type of sensor. For list of values see below.
- **unit_of_measurement** (*Optional*): Override automatically detected unit of sensor.
- **aliases** (*Optional*): Alternative RFLink ID's this device is known by.

- average_windspeed
- barometric_pressure

### {% 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:
- Disable automatically adding of unconfigured new sensors (set `automatic_add` to `false`).
- Hide unwanted devices using [customizations](/getting-started/customizing-devices/)
- [Ignore devices on a platform level](/components/rflink/#ignoring-devices)
