You might want to look at a seperate controller for your lighting control
Either dedicated cards on a PC or for easier programming  HomeVision
Comfort might be quite a handfull to operate a full house lighting
the main problem you face is one of output ports
the advantage of X10 is that for one interface you get 256 outputs ( A>P 1>16)
the max for everything on Comfort is 64 and you can soon use those up on other things
 
I have gone for comfort relay control in my garage for lighting and it works very well
In my house I use Homevision and X10 with varied control (Computer/swithches/touchscreens/rf switches/pronto)
 
One problem using secondary switches to control X10 or relays directly is that your main controller doesnt then know the state of the lights, this may not matter, but I find one master unit controling all lights and all control of those lights going to that controller allows for smooth automated control (if there is such a thing :)  )
 
I use ACE to connect Homevision and Comfort together
hope this helps

I'm sure this has been discussed before, but I'd apreciate to hear a fresh round of debate on this point. I'm doing a complete rewire on the house - so there's two choices for control of lighting: X-10 or Mains relays. Either way we're gonna use a star pattern as this provides maximum longterm flexibility.
 
I figured LD11's are hard to beat for their versatility, but for switching fluorescents, or applicances why spend £40 on an AD10 when I can have DIN mounted relays for under a tenner? Of course a mains relay like this will need to be CAT fived back to the HA interface, but aren't relays more reliable than X-10 anyway?
 
So here are my three questions:
 
1. All things being equal in a star wiring pattern - would you go for DIN mounted relays or AD10s?
 
2. Are there any obvious gotchas when hooking up manual (rocker type) wall switches for local control if I go for the DIN mounted relay option? Suppose for example I need two way control for the lights on the stairs?
 
3. My consumer unit and DIN rails are all in the boiler room next to all the HVAC stuff. The boiler room is also very well sittuated for running wires almost anywhere. However, Node Zero (Comfort, AV gear, Data Hub, Telephony etc) is in a large cupboard in the centre of the house. Given that I first need to make the choice between AD10's verses DIN mounted mains relays - is there any particular advantage to having Comfort located close to the DIN rails in the boiler room rather than in Node Zero.
 
Thanks for your help
 
Chris
