I'm not sure I understand. The Raspberry Pi runs constantley running Pcp 3.02. When the "Player" is switched on via LMS web GUI or via IPeng, OrangeSqueeze or any other means the GPIO goes high powering the amps On if you Stop or Pause playback or the track finishes, powersave will, after the determined time turn off the "Player" the GPIO then goes low powering off the amp(s). I do this in 2 different ways 1) GPIO triggers an SSR for one type of amp and 2) The GPIO directly powers the "Enable" input of my ICEPower 300ASC's *Players:* SliMP3,Squeezebox3 x3,Receiver,SqueezePlayer,PiCorePlayer x3,Wandboard *Server:* LMS Version: 7.9.0 - 1475786002 on Centos 7 VM on ESXi 6 on Dell T320 *Plugins:* AutoRescan/BBCiPlayer/PowerSave/PowerSwitchIII/Squeezecloud *Remotes:* iPeng8/Orangesqueeze/PC/Jivelite *Music:* 383GB,1269 albums 17756 songs 4381 artists mostly FLACs *Want a webapp ?* See http://forums.slimdevices.com/showthread.php?104305-Webapp-for-LMS ------------------------------------------------------------------------ Jeff07971's Profile: http://forums.slimdevices.com/member.php?userid=49290 View this thread: http://forums.slimdevices.com/showthread.php?t=105997 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
