Hi! I've developed a freeware software to allow PLCBus users to control devices using their PCs. This software allows you to design "plans" with devices, macros, weather information, etc., and link them together. It also contains a scheduler that allows you to automate control of your devices, and respond to events.
Then you can simply view those plans with any browser and control your devices remotely with a palm, PC, etc.
Anyone interested can download from http://hometomation.com/homeplanner
Your feedback and suggestions will be more than welcome.
