First of all, I would like to introduce myself!
My Nickname is Defla, I am 32 from Paris (France) and I am a programmer.
I will try to use my best english, but please, do not blame me if I do spelling mistakes

I am currently restoring my house and would like to set up something allowing me to control my room lights, garage door, Home Cinema, and so on..
I am totally newbie and do not know anything about how to do it.
I am considering buying the HouseBot sofware as it seems very interesting and powerful, but once the software is bought, I do not know what to do

For example, I am considering acquiring a Denon AVR-2310 A/V Ampli, Would I be able to control it with HouseBot ? How ? Using the RS 232 port ?
If I want to control my room lights, how to do it ? Do I need to buy some specific appliance/stuff to do it ?
It would be very kind of you if you could help me because I am really lost :/
