I’m working on home automation project. All project (software and hardware) is under GNU Open Source license. Some parts of the project is working now and can be seen under address http://idom.wizzard .one.pl (only Polish language version). Now I have finished and tested hardware of light dimmer, shutter controller, temperature and humidity controller, interface from RS485 to USB and partially finished PC application controlling the whole system.
If somebody is interested in this project and have a will and time to help me please contact me. I also want to translate the web page into English, so any native speaker to make language corrections is needed too
Any suggestions and ideas how to continue and develop this project will be greatly appreciated.
