What's the deal with Fibaro Z-Wave relays?

Ok, so some background. I have a weird collection of kitchen lights under my kitchen units as well as my cooker hood that are all controlled via a really inconvenient switch above/beside the hood.

Due to the random combination of lights, I can’t Hueplace (replace with hue :wink: ) them so I’ve been looking at adding a z-wave system and some relays.

The Fibaro units seem to be the most obtainable in the UK but I have no idea what the difference between these units is and what I need:
Fibaro FGS-222 Dual Relay Switch
Fibaro FGS-212 Z-Wave Relay Switch
Fibaro FGD-212 250 W Universal Dimmer

P.S. I was already thinking of adding Z-Wave infrastructure to get some of Fibaro’s universal sensors

yep would like to know better too. I think is probably needed the help of an electric engineer …

Not an electrical engineer, but am pretty certain that:

The dual relay switch has two inputs and two outputs. So two devices can be connected and switched individually.
The normal relay switch has only one device/output which can be switched.
The dimmer is not really a switch. It outputs a signal (pwm ?) making lights fade…

Sanders is right, though the dimmer supports both trailing and leading edge modes (Vesternet are really good in that they provide links to the manuals for pretty much everything they sell).

Given what you describe, I’d say that you’ll want either the single or dimmer installed with the switch, so that the switch controls them (via the module), and you can control it via Z-Wave.

I’m still not entirely sure what the Universal Dimmer does?

See Vesternet’s page (I’m just a happy customer) for links to the documentation and a better description than Amazon.

In short, it’s a dimmer that supports all bulb types, since many don’t support LEDs. In this case, these support incandescent bulbs, fluorescents, LEDs, and even transformers.
