Welcome to myhomelab. You may control the exterior and interior lights, and the wind mill as you were in my home at Berkeley. Try clicking the lines on the left and wait for the image above to refresh. The (.cgi file) shows one of the Perl files in the server. The exterior light may not be visible during the day because of the existing daylight in the lab.
The image above shows myhomelab with the room temperature and humidity, the lights and the wind mill. This remote control uses the browser as a user interface and the wiki pages created using the OS X Server app. The wiki services provides access control for single users, groups, or everyone like in this page. The commands are Perl files executed, as .cgi files, in the local mac mini server at the myhomelab location.
