I was wondering about the UK regulations and a 0V light switch inside a bathroom Zone 3. The switch would control a QRI (2 relays for mirror light and ceiling light). Is there any problem with that approach?

You could of course use a QBI, or DFP or similar. In my design I'll be using something like a DFP or IR Receiver + QBI so I also have control over audio in the bathroom (relayed to player / amp in bedroom) plus 2 light channels one swiched and one dimmed via QLD.
If havinng dimmed lights is a posibility remember when you terminate at the QRI to leave enough slack in the cable to allow you to re terminate on an adjacent device in the future.

Switches
After some trials the public consensus (read my wife!) had voted for the most practical system available....
A boring 2 gang white grid plate with 2 one way switch connected to the QRI as 2 digital inputs and the logic following digital state. I had to remove the retractive swiches as they didn't look "normal" or "easy to use".
PS: I used 2 pair phone cables for that as they are cheap

Not so boring if I find the right stuff
I was looking arround and came up with a challenge. There are some proximity sensing devices that you can put behind the tiles and thus switch light. However, they use the 230V and I want to use Idratek! So it is DIY time... I am looking for ideas from the electronic parties on this forum. Capacitance? Can I use power from the QRI? Suggestions are appreciated. The goal is a proximity sensor that can be placed behind a 5 mm tile and can provide info for Cortex/Reflex.

You mean something like this http://www.letsautomate.com/10690.cfm?
Instead of operating a light you could always use it to switch a relay.
Relay from here would do the trick.
Or I guess if you have a Maplin store nearby then they may have something suitable.IF YOU CAN'T FIX IT WITH A HAMMER, YOU'VE GOT AN ELECTRICAL PROBLEM.

Relay
Yes, that is what I saw as well as this but they all need to connect into a power supply. I am also looking at a DIY with a QT100 connected to an idratek module. The IC needs 5v and the question that remains to be answered is if sensitivity will be enough to get through the tile. I will post here but still open to suggestions

On the Sensor UK site they show you how to mount a sensor switch behind a tile. So I guess the sensitivity is ok.IF YOU CAN'T FIX IT WITH A HAMMER, YOU'VE GOT AN ELECTRICAL PROBLEM.

The company that makes then now does normal switches as well as those PLCbus ones.
