abstract: Despite the rumors, the HCS II project is not dead. In fact, HCS has been licensed and is now an open-source project. In this article, the author brings us up to speed on the HCS II project's past, present, and future. The HCS II is an expandable, standalone, network-based (RS-485), intelligent-node, industrial-oriented supervisory control (SC) system intended for demanding home control applications. The HCS incorporates direct and remote digital inputs and outputs, direct and remote analog inputs and outputs, real time or Boolean decision event triggering, X10 transmission and reception, infrared remote control transmission and reception, remote LCDs, and a master console. Its program is compiled on a PC with the XPRESS compiler and then downloaded to the SC where it runs independently of the PC
