The rflink component support devices that use Rflink gateway firmware, for example the Nodo Rflink Gateway. Rflink gateway is an Arduino firmware that allows communication with 433Mhz devices using cheap hardware (Arduino + 433Mhz tranceiver).

First you have to set up your rflink hub.

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:

# 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:

# 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 433Mhz 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
• Ignore devices on a platform level
