.....In your case of course you have KNX bus cabling in place and already have a load of KNX devices & your comfortable with it so go with that - take a look at our Bash-KNX package for 0710.....
I'm sure your knowledge and experience of implementation outcomes exceeds mine, and I'm happy to defer to you on that. I come from an old school perspective on networking (I'm a systems manager in "real life"). I always prefer a physical wiring solution over a wireless solution. It has higher bandwidth (potentially), lower latency, no blackspots, can be used to transmit power as well as bus messages, is less susceptible to interference, and is not subject to significant EMI.We are installing both ZWave and KNX for customers currently. We like both to be frank. Hari has done an excellent job with his new open Zwave driver and we will be using that and contributing functionality and capability around that in the new year.#
I'm not doubting that z-wave is good, but I'll take a good wired system over a good wireless system every day of the week.
The customer I mention here with the KNX installation that we are currently installing was already partway through installing the bus wiring when we got involved and so there was a good reason for going KNX. However we are seeing 75% of our customers decide to go the KNX route at this end of the market when they weigh up all the pluses. Reliability wise we see no issue at all with ZWave as the Mesh network it forms improves as the number of devices increases. In terms of latency & speed we see very little difference in the two either - the difference is marginal at best. In terms of installation cost ZWave wins hands down to be frank as there is no cabling to be run and the individual devices are for the most part less expensive than KNX equivalents - in addition the flexibility to extend/add/change your ZWave network without limitation is an immensely powerful benefit to us and our customers.
All the best

I'm not doubting that z-wave is good, but I'll take a good wired system over a good wireless system every day of the week.We are also in the middle of a very large KNX installation for a customer in the London area - it has all the KNX features you have listed and probably a few more too ;-). We are installing our LinuxMCE-0710 based Dianemo software which will be used as a secondary controller for scene changes etc as you describe. See my earlier post to this thread for information on the Bash-KNX API we have developed. Our Bash-KNX is built on top of our DCE-Whisperer which is a DCE API written in Bash that makes building new DCE device interfaces easy (DCE-Whisperer is included in the Bash-KNX package). The Core is centrally racked in this installation, will include 3 x Freesat cards and will also control multiple external Sky-HD boxes and a 6x6 Kramer HDMI Video Matrix for routing the HD over Cat5 to multiple Screens and a large Home Cinema Projector installation. In this system we are using multiple ASUS Eee-box's (one mounted behind each display and running at 720p) and one Eee-Box in the rack for the Home Cinema. We also have a wall mounted Eee-Top touchscreen in the Kitchen area. We will also be using a Comfort alarm panel with a KNX interface.
I also have a central wiring room/cabinet. In my case it's about 0.8m wide and just over 3m long. It stretches under the stairs and at the two ends it touches the lounge and the dining room. I mount all my A/V equipment in hatches into the electrical room, and all the cables return there. Consequently all of my wiring is terminated in that cabinet/room (which also houses a 46U rack). There's a lot of wire, but it leaves the whole system very flexible and easy to rewire or reprogram.The Eee-box will upscale SD content to 720p and also to 1080p but is not really suitable for playing true HD encoded content. However for upscaled SD it is really an excellent choice even when driving 2.5-3m wide projected Home Cinema installations. The Eee-Top is a great machine too but curently the only way to get this unit working is to use the Vesa driver and the Intel driver does not handle the backlight correctly currently. However the performance under the Vesa driver is adequate and we do expect that the Intel driver will get a fix for the backlight bug in the near future.
Thanks for that information. For the large full HD screens in the lounge and dining room I have MD's mounted in my electrical cabinet (accessible from the respective rooms). I have a 28" 1080p screen that I was planning on using as a portable with a eee box. I might try building a custom MD to handle full HD for this. I'm very tempted by the eee top's for portable controllers/integrated MD's. I'll probably buy one and have a play.So in many ways this installation seems to match the one you are planning.
All the best for Xmas and the new year.
Thanks for that. I imagine it's a project that's going to take me a while. It should be fun. The fact that all of my systems work independently means that the integration is icing on the top, rather than critical. I'll be playing over time to try to get everything working together. It should be fun.
.....Couple of questions,
Did you go with DALI for your lights, (with one of the KNX-DALI gateways)?
Did you pay for the full version of ETS, or stick to the ETS Basic devices?
Have you looked at HomeServer from Gira?
you must have missed Z-Wave. KNX looks a bit shopworn in comparision (for our usage patterns, I'm not talking about a some hundred floor office building)....
....You may want to read a bit farther, because yes. LinuxMCE can control devices itself in very complex ways that no current hardware solution can duplicate. However, your choice of KNX may have been a bit foolhardy. Our implementation of EIB/KNX is very basic......
