This integration provides support for Internet Radios based on the Frontier Silicon chipset. Some of the manufacturers which offer products based on these chips include: Hama, Medion, Slivercrest, Auna, Technisat, Revo, Pinnel, etc. These devices will be usually controlled by the OKTIV or UNDOK apps.

Supported models

Frontier Silicon is used by many different brands of radio manufacturers.

Supported devices include, but are not limited to:

This integration was developed and tested with a Roberts Stream 94i.

If your device is supported by the OKTIV or UNDOK apps, then it is also supported by this integration.


The integration supports automatic discovery of your Internet Radio. If you need to set up the device manually, please provide the device IP-address. Some models use a separate port (2244) for API access, this can be verified by visiting http://[host]:[port]/device.

The default PIN for Frontier Silicon-based devices is 1234. You can set the PIN code of your device (depending on manufacturer) under: MENU button > Main Menu > System setting > Network > NetRemote PIN setup

Frontier Silicon can be auto-discovered by Home Assistant. If an instance was found, it will be shown as Discovered. You can then set it up right away.

In case your device (friendly name) is called badezimmer, an example automation can look something like this:

# Example configuration.yaml automation
alias: "Bathroom Motion Detected"
  platform: state
  entity_id: binary_sensor.motion_sensor_166d0001171111
  from: "off"
  to: "on"
  service: media_player.turn_on
    entity_id: "media_player.badezimmer"

Notes and Limitations

Some older devices may require setting up a session to process requests. This is automatically detected by the underlying library. There is always a single user (session) controlling a device, which means that once Home Assistant connects to a device all other sessions will be invalidated.

This renders the usage of [UNDOK] almost impossible for these older devices, as the Home Assistant integration polls the device state every 30 seconds or issues a command by creating a new session. In that case, you have to disable the integration if you want to use UNDOK.
