Hi!
I'm new at home automation, so please help me to set up a demo system.
Let's say, that I have:
- a push button
- a (dimable) 220V tungsten lamp
- a PC with OpenRemote installed
My requirements:
1. One push on the button (light is off): dim up the lamp in 1 second
2. One push while light is on: dim down the lamp in 1 second
3. If lamp stays on for 30 seconds dim down the light in 5 seconds
What else should I need for this demo project:
a) Let's say I go for wired KNX: what KNX devices, wireing should I need? How can I have one?
b) How can I connect my KNX devices to the PC?
c) Can I set up OpenRemote for this job? How will OpenRemote detect my connected devices? Can I monitor/log the state of the light?
d) How can I extend this demo with other (KNX) devices: motion detector, etc. Where can I buy these hardware?
Thanks,
Balázs

Devices are programmed with addresses per installation, using a proprietary ETS software, and you enter that address when you configure your device in the modeler.
Monitoring components are coming in the 2.0 release, the priorities were discussed here: DEV - Current Work and Priorities
EIB Markt (http://www.eibmarkt.com) seems popular. I'm not sure how people deal with getting the ETS, you'll have to ask the KNX-heads.

If you buy new KNX hardware you need to use Windows and buy the ETS software to be able to program the address of your component? Can this not be done using a (open?) protocol through a gateway between your IP network and the KNX/EIB net?

As for the protocol, I haven't yet gone through the details of management primitives in the Common EMI frame so cannot say with certainty how feasible it is to write an ETS replacement (if it is, or isn't). I don't know of one (which would prove it can be done) but that doesn't mean it don't exist.
