Ocelot

From CT.wiki

The Ocelot is a standalone HA controller manufactured by Applied Digital Incorporated (ADI). It is the successor to the popular CPUXA controller. The Ocelot has a powerful control language (C-Max) that includes if-then-else logic. It also can control X-10 units, in addition to sending and receiving IR signals.

A large number of sensors (called Bobcats) and add-on modules are available for it. There is also a big brother to the Ocelot, called the Leopard II. It is basically an Ocelot with a built in touch screen interface.
