Are there 2-wire Z-Wave dimmers for Led-lights?

[Bikey]

Hi,

I'm just starting with Z-Wave (bought a ZWave.Me Z-Wave Plus Stick and a PIR), and I'm now looking for a future proof built-in dimmer for my lamps.

It should be capable of dimming my LED-lamps, and use a 2 wire system (phase and switch-wire to the lamp, as is customary in The Netherlands). It seems that this combination 2-wire and capable of dimming LED's does not exist. Does anybody has experience/tips?

Thanks!

P.s. I don't really like a combination with a "dimmer bypass" which is essentially burning and wasting the energy just saved by using LED's!

Qubino dimmer?
Don't understand the 2 wire thing do.

Qubino dimmer?
Don't understand the 2 wire thing do.

The Qubino needs 3 wires: the phase 230 V(brown), 0 V (blue) and the switched wire (black) towards the lamp.
In the Netherlands, all wall-switches or dimmers only use the brown and the black wires, so the blue wire is usually not present in the wall.

So the if you replace an existing dimmer with a Qubino you need to install an addition (0 V blue) wire; not nice!

The issue with a LEDLamp is that it doesn't leak enough current to power the DImmer in case the light is off, hence the need for the bypas (parallel resistor).
Not sure if this really cost more energy as I would think that the energy consumption is determined by the Dimmer, not the bypass resistor in case the light is switched off.

Strange that is so much different than Belgium. Here we have in every switch phase and 0.

You have a point. Conversely, if the lamp is on the resistor will consume additional power. I have no idea how much that is to be honest. Anybody an answer to that?

I think I have to choose the Fibaro2 dimmer then, as it also works with 2-wires.
