Current Configuration

The spacecontrol project consists of two hardware parts. A small one and a big one. For more documentation on how they were both built look on the subpages. There is also a purely software part to do a remote soft poweroff some servers.

Currently only the small version is active.

  • This first version can control up to 4 220V devices.
  • It can do a soft poweroff of four servers in the space.
  • Software running on the audio server.
  • Currently 4 lamps in the main room are hooked up.


webinterface (low level)

This a very crude but functional webinterface to control our spacecontrol components. It should be self explanatory. Just visit http://spacecontrol while in the space select one of the tab sheets and click the buttons.

webinterface (graphical)

There is now also a graphical webinterface available. This is based on the opensource project HomeAutomation. For the moment this interface can be tested by visiting http://gatekeeper while in the space. The username needed to enter this page is "Whitespace" the password you should be able to guess. An installation guide can be found here.

This setup is being tested, not yet stable but please try and report problems.
Known issues:

  • Webinterface will not load when the Audio server is not running. Trying to load anyway will cause a loop that fills the error log (/var/log/lighttpd/error.log) of lighttpd until the drive is full. Without any space mysqld won't come up and possibly other things will fail as well. Just empty the log file to fix things again.
Android App

The current version of spacecontrol supports the DomoticHome Android app. This application can be found in the Android market (direct link to app). The first time you use the app go to settings and fill in the following:

PORT: 80

Click save and then when you hit Sync the current Spacecontrol configuration should be loaded. A menu structure will then appear in the main application window allowing you to control the connected appliances.

Insanity mode

Use FireBug or the Chromium thing to add ids 'on' and 'off' to the 'all on' and 'all off' buttons. Then run:

function hax( time ){ if (typeof foo != 'undefined') {return 'bar';}; document.getElementById('on').click(); document.getElementById('off').click(); setTimeout( "hax( " + time + " )", time ); } hax( 1000 );
