Zwave dimmer switches and 2/3 wire systems?

[gmc]

Just starting out with home automation and have the razberry running with domoticz.

In the lounge and dining room I have 2 dual way switches. For my first home automation project I would like to replace the dual switch in the lounge with a dimmer switch. I've read a few forums and am a bit confused on the type of dimmer switch required. Some mention master and slave devices are required.

Since the lounge and dining room switches are fairly close I would be be happy with replacing the lounge dual switch with a dual dimmer switch, leaving the dining room switch as a on/off switch, or must both be replaced with dual dimmers?

Was looking at something like the TKB_TZ65-D - would I need 2 of these?

The product also mentions it requires a 3 wired system, which brings me onto the next question.

I opened the switch up and there are 3 red wires, a blue and a yellow going to it - how can I check if its a 2 or 3 wire system?

If it is a 2 wire system then what other options do I have?

I would recommend taking a look at the application notes on vesternet.com. They give you some guidance on dual switching and different wiring schemes. http://www.vesternet.com/resources/a...-notes/apnt-23
Looks to me from the image that you have one single switch on the left (2 core both red, live and switched live) and another that has 2 way switching wired on the right using a strap wire ie 3 core + earth cable. See this link for info on how standard 2 way lighting works as this should help you identify the wiring you have installed. http://www.vesternet.com/resources/a...n-notes/apnt-2
I achieve 2 way lighting control for the landing using fibaro dimmers using the existing cabling as detailed in that app note 2.

Thanks for the link - very useful. You are correct - the one switch is a single switch. I always thought it was a 2 way switch but the other half never worked. After opening up the other switch I found out its not even connected. Previous owners really did a shoddy wiring job.
