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 ) them so I’ve been looking at adding a z-wave system and some relays.
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.
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.
