MPD Binding

Music Player Daemon (MPD) is a flexible, powerful, server-side application for playing music. Through plugins and libraries it can play a variety of sound files while being controlled by its network protocol.

By help of the openHAB MPD binding, you can e.g. start/stop playing music in specific rooms / on various channels and change volume.

Binding Configuration

This binding can be configured in the file services/mpd.cfg.

Property Default Required Description
<player-id>.host   Yes IP address or hostname of the MPD player
<player-id>.port   Yes Port number on which the MPD player is listening

where <player-id> is a unique name that you give for the player, such as livingroom, bath, etc.

Item Configuration

The syntax for the Exec binding configuration string is explained here:

mpd="<openHAB-command>:<player-id>:<player-commandLine>[,<openHAB-command>:<player-id>:<player-commandLine>][,...]"

where the parts in [] are optional.

The Player-Id corresponds with the configuration in mpd.cfg where one has to configure the MPDs:

Examples

Here are some examples of valid binding configuration strings:

mpd="ON:bath:play, OFF:bath:stop"
mpd="INCREASE:bath:volume_increase, DECREASE:bath:volume_decrease"

As a result, your lines in the items file might look like the following:

Switch Mpd_Bathroom_StartStop	"Start/Stop"	(Bathroom)	{ mpd="ON:bad:play, OFF:bad:stop" }

Track Names

Support for track names was added in 1.5 and also ability to set exact volume for dimmer items (previously only increase/decrease actions were available)

Items

String CurrentTrack    "Current track [%s]" { mpd="TITLE:bad:tracktitle" }
String CurrentArtist    "Current artist [%s]" { mpd="ARTIST:bad:trackartist" }
String ConcatInfo       "Now playing [%s]"

Switch Mpd_Bathroom_StartStop       "Start/Stop"   (Bathroom)  { mpd="ON:bad:play, OFF:bad:stop" }
Switch Mpd_Bathroom_NextPrev        "Track control"   (Bathroom)    { mpd="ON:bad:next, OFF:bad:prev" } 
Dimmer Mpd_Bathroom_VolumeControl   "Volume [%d%%]"       (Bathroom)  { mpd="INCREASE:bad:volume_increase, DECREASE:bad:volume_decrease, PERCENT:bad:volume" }

Rules

To concatenate artist and title:

rule "concat"
when
  Item CurrentTrack received update or
  Item CurrentArtist received update
then
  ConcatInfo.postUpdate(CurrentTrack.state.toString + " / " + CurrentArtist.state.toString)
end
