I have a question that was probably addressed in this forum, but I could find a answer that I like.
I have a background in electronics and programming, but don't know noting of home automation (have order some books !).
I'm looking for a home automation controller to my new bough house. I want a cheap but reliable system. For now, my main objectives are to control some X10 devices, the irrigation system and to control or implement a security system (more on this latter). I would like the controller to be expandable, by the addition of new plug-in modules and/or by implementing a network of modules (rs-485 or similar). I think this will give me plenty of room to play in the future. On the software side, I also would like to be able to program the system using linux and open source tools.
I think that the alternatives are a =93of the shelf=94 semi-professional system (Ocelot?), some sort of kit or DIY system like the HSC_II (or HSC_C?) and a SBC, but since I don't now noting about this subject and reviewing all the systems on the market today would take me forever, I would appreciate the opinion of you all.
Finally, one other question: what are the advantages /disadvantages of using an separated security system, as opposed to integrate the security system in the H.A. controller.
