The vendor of -my projector, <a href="https://www.infocus.com/">InFocus</a>, had been -sensible enough to document the serial protocol in its user manual, so -it is easily available, and I used it some years ago to write -<a href="https://github.com/petterreinholdtsen/infocus-projector-control">a -small script to control the projector</a>. For a while now, I longed -for a setup where the projector was controlled by Kodi, for example in -such a way that when the screen saver went on, the projector was -turned off, and when the screen saver exited, the projector was turned -on again.</p> - -<p>A few days ago, with very good help from parts of my family, I -managed to find a Kodi Add-on for controlling a Epson projector, and -got in touch with its author to see if we could join forces and make a -Add-on with support for several projectors. To my pleasure, he was -positive to the idea, and we set out to add InFocus support to his -add-on, and make the add-on suitable for the official Kodi add-on -repository.</p> - -<p>The Add-on is now working (for me, at least), with a few minor -adjustments. The most important change I do relative to the master -branch in the github repository is embedding the -<a href="https://github.com/pyserial/pyserial">pyserial module</a> in -the add-on. The long term solution is to make a "script" type -pyserial module for Kodi, that can be pulled in as a dependency in -Kodi. But until that in place, I embed it.</p> - -<p>The add-on can be configured to turn on the projector when Kodi -starts, off when Kodi stops as well as turn the projector off when the -screensaver start and on when the screesaver stops. It can also be -told to set the projector source when turning on the projector. - -<p>If this sound interesting to you, check out -<a href="https://github.com/fredrik-eriksson/kodi_projcontrol">the -project github repository</a>. Perhaps you can send patches to -support your projector too? As soon as we find time to wrap up the -latest changes, it should be available for easy installation using any -Kodi instance.</p> - -<p>For future improvements, I would like to add projector model -detection and the ability to adjust the brightness level of the -projector from within Kodi. We also need to figure out how to handle -the cooling period of the projector. My projector refuses to turn on -for 60 seconds after it was turned off.
