Annoyingly, I had all the electrics done in this house about 6-8 months before I considered home automation.
Annoying for two reasons:
I should have asked for CAT 5 to every room
I should have asked for deep pattress boxes (probably deep plastic pattress boxes.)
My walls are plenty thick enough and they mess with the WIFI, but the electricians chose to use the shallowest pattress boxes they could find. This probably made their lives more difficult, some of them have a lot of wiring scrunched up behind them.
I, too, have been looking for wall switches that are nicer looking, not just thin pieces of plastic. I was expecting to find a lot of these, but I guess not. I have a couple of the TKB switches, which manage to be expensive and yet look very cheap. One has also been replaced as it failed recently.
I was originally looking at the Vitrum, but these were/are very expensive and I could find no mention of them in use on any of the forums, here and elsewhere.
http://www.switchtovitrum.com/en/2206-2/Then I ended up with an MCO 4-gang in a Vesternet sale. Pre Indigo 7 these worked in that Indigo could send an on/off and the light channels would respond. However, they would not report back to Indigo if they were changed at the switch, effectively making them a very expensive LightwaveRF. I have not tried this unit with Indigo 7 (yet).
The other thing I have found very tricky is the tiny connection points, often grouped together. Just wiring them up is bad, but then pushing them back into a pattress box with all the wires scrunching up... it doesn't fill me with confidence. I note that the Fibaro switch version 2 (1 and 2 switches) have made the connection points a lot bigger.
As I mentioned elsewhere, about a year ago, I'm going to move away from the zwave control being in the actual switch, either part of the switch or behind it. It really limits the front end choice, the actual switch, and is tricky to fit anyway. I have been looking to fit Fibaro devices into the ceiling roses instead. This led to the next problem, finding a ceiling rose that is big enough to take everything!
