Thanks to the SqueezeIR applet, one can use a
Squeezebox Controller to send infrared commands to auxillary equipment
.

The attached SqueezeIR Trigger plugin is a SqueezeIR helper that allows
one to send an IR signal once a specific Squeezebox player is turned on
or off. I wrote it to power on an amplifier whenever the Squeezebox
Receiver connected to it is turned on. And, even better, power off the
amplifier when the Receiver is turned off. That, I used to forget quite
offen...

This is my first attempt at writing an LMS plugin. It is based on the
PowerMonitor plugin. While the plugin works for
me, it might not work for others. Please let me know about any problems
you enncounter and suggestions for improvements you have.

There are a couple of improvements I can think of already. I hope more
experienced plugin writers could point out how to implement those or
where something similar has been implemented already:
    
- Provide a drop-down list of Squeezebox players on the settings page.
  I'm not sure how to properly filter out players that can't be
  controller by IR signals.
- Provide a drop-down list of Squeezebox controllers on the settings
  page. I don't know whether there is a way to list those at all.
- Validate all settings on input. How can I implement value checking
  in the settings page?
- Support the configuration of an unrestricted number of notifications
  (player state changes) and potentially different players and
  controllers. How can I allow the user to specify as many sets of
  attributes as she/he likes, i.e. add fresh configuration sections and
  delete existing ones?
  
For other users it might also be necessary to add the following
functionality:
    
- Differentiate between powering on and powering off
  

Actually, I don't want to put too much efforrt into this because I still
hope there might be a way to integrate the functionality into the
SqueezeIR applet. On the other hand, there are many other notifications
a plugin like this might react to, see the documentation of command line
interface included in the server's help pages and the
Slim::Control:Request module. And there are many other actions one might
trigger other than sending IR signals.

Have fun, maf
