Frontier Silicon Radio Binding - juri8/openhab GitHub Wiki

Documentation of the Frontier Silicon Radio binding for Internet Radios based on the Frontier Silicon chipset.

Introduction

This binding has been developed and tested with the Hama IR110 and Medion MD87180 internet radios. The MEDION® P85040 (MD 86988) is also supported.

MEDION LIFE P85044 (MD 87180) Hama Internetradio IR110 MEDION LIFE P85040 (MD 86988)

You can easily check if your IP radio is supported:

  1. Figure out the IP of your radio (e.g. by looking it up in your router)
  2. Figure out the PIN that is configured for the radio (somewhere hidden in the radio's on-screen menu); or try the default pin 1234
  3. Go to your web browser and enter: http://<IP>/fsapi/CREATE_SESSION?pin=<PIN>
  4. If the response is similar to FS_OK 6836164442, your radio is most likely compatible with this binding
  5. If you radio works with this binding, please add it to the list above by Editing this page!

For installation of the binding, please see Wiki page Bindings.

The Frontier Silicon Radio binding is included since openHAB 1.7.0.

Binding Configuration

Configuration is done in the openhab.cfg file (in the folder ${openhab_home}/configurations):

############################### Frontier Silicon Radio Binding ###################################
#
# Hostname/IP of the radio to control
#frontiersiliconradio:radio.host=192.168.0.100

# PIN access code of the radio (default: 1234)
#frontiersiliconradio:radio.pin=1234

# Portnumber of the radio to control (optional, defaults to 80)
#frontiersiliconradio:radio.port=80

# The number of milliseconds between checks of the radio
# (optional, defaults to 60 seconds).
#frontiersiliconradio:refreshInterval=60000

# Cache the state for n minutes so only changes are posted (optional, defaults to 0 = disabled)
# Example: if period is 60, once per hour all states are posted to the event bus;
#          changes are always and immediately posted to the event bus.
# The recommended value is 60 minutes.
#frontiersiliconradio:cachePeriod=60

Some notes:

  • 'radio' is an identifier that can be replaced with your custom identifier, e.g. 'bedroom' or 'radio-kitchen'. This allows to use the binding also for multiple radios.
  • The pin may vary from radio to radio, you can typically look it up in the radio settings.
  • 'refreshInterval' and 'cachePeriod' are global settings that apply to all radios.

Item Binding Configuration

There are different types of item bindings, all of them are qualified with the device's identifier used in the openhab.cfg file:

frontiersiliconradio="<identifier>:<property>"

Example for the power state of a device with identifier radio:

Switch RadioPower "Radio Power" { frontiersiliconradio="radio:POWER" }

A list of all properties and their possible item types is given below:

item item type purpose changeable
POWER Switch power state yes
MODE Number radio mode (details about mapping below) yes
VOLUME Number volume yes
MUTE Swtich mute yes
PLAYINFONAME String title of current playback, e.g. radio station no
PLAYINFOTEXT String additional information, e.g. current song no
PRESET Number select preset, e.g. configured radio stations yes

The radio mode property is just a number that specifies the radio mode which may differ for each radio. This is why there is no fixed mapping implemented. For radios listed above, the mapping is as follows (please add your radio mapping, if it differs!):

radio mode Hama IR110 Medion MD87180 Medion MD 86988
0 Internet Radio Internet Radio Internet Radio
1 Spotify Music Player (USB, LAN) Music Player
2 Player DAB Radio FM Radio
3 AUX in FM Radio AUX in
4 - AUX in -

Example

Items:

Switch RadioPower         "Radio Power" (gRadio) { frontiersiliconradio="radio:POWER" }
Number RadioMode          "Radio Mode [%d]" (gRadio) { frontiersiliconradio="radio:MODE" }
Switch RadioMute          "Radio Mute" (gRadio) { frontiersiliconradio="radio:MUTE" } 
Number RadioVolDimmer     "Radio Volume [%d %%]" (gRadio) { frontiersiliconradio="radio:VOLUME" } 
String RadioPlayInfoName  "Play Info Name [%s]" (gRadio) { frontiersiliconradio="radio:PLAYINFONAME" }
String RadioPlayInfoText  "Play Info Text [%s]" (gRadio) { frontiersiliconradio="radio:PLAYINFOTEXT" }
Number RadioPreset        "Preset" (gRadio) { frontiersiliconradio="radio:PRESET" }

Sitemap (presets and mode are radio-specific, this is why their mapping is specified here):

Frame label="Radio Control" {
    Switch     item=RadioPower
    Selection  visibility=[RadioPower==ON] item=RadioPreset mappings=[0="1Live", 1="WDR2", 2="SWR3"]
    Selection  visibility=[RadioPower==ON] item=RadioMode   mappings=[0="Internet Radio", 1="Spotify", 2="Player", 3="AUX IN"]
    Slider     visibility=[RadioPower==ON] item=RadioVolDimmer
    Switch     visibility=[RadioPower==ON] item=RadioMute
    Text       visibility=[RadioPower==ON] item=RadioPlayInfoName
    Text       visibility=[RadioPower==ON] item=RadioPlayInfoText
}

Developer Info

If you would like to extend this binding and contribute further functionality, here is some technical information about it. The communication with the radio is realized via simple HTTP requests. Unfortunately, there is no official documentation of the API for the frontier silicon chipset, but there are some sources around the internet (flammy/fsapi on github, for example). Until now, only the following requests are implemented:

  • netRemote.sys.power
  • netRemote.sys.mode
  • netRemote.sys.audio.volume
  • netRemote.sys.audio.mute
  • netRemote.nav.action.selectPreset
  • netRemote.play.info.text
  • netRemote.play.info.name

If you like to add further actions, have a look at FrontierSiliconRadio.java.
