    The primary driver, the IDLV, accepts two forms of dimming input. Either varying resistance, or 0-10v signal. The only 0-10v controller I've been able to find is the Qubino:

    From what I can tell, this would require two z-wave devices to fully operate the lights.

    The input terminals of the qubino allows you to connect switch(s), that in turn control the quibino. In this configuration it would not need a 2nd zwave switch.

    You may be able to associate a scene controller like GoControl WT00Z5 with the Quibino 0-10v dimmer. If you have "0" on the dimmer you have your off control.

    If/when the WD100/200 firmware gets upgraded to allow direct associtaion that device will work too. Put the driver on a z-wave controlled circuit and you could use double tap to power off the driver.

    I am not clear why you cannot just put a dimmer on the driver.

    Z-Wave equivalent of the Control4 "Decora" 0-10V Dimmer?

    Reference the Control4 "Decora" series 0-10V dimmer switch here:

    My situation: I'm planning to install LED COB based luminaires in an upcoming strip out and re-sheet of the 80-year-old, asbestos-lined cyclone hazard I call a home.

    Each 'string' of LEDs (2-6 luminaires depending on the room) will be driven in parallel by a meanwell constant voltage driver with PWM dimming output. The emphasis there is on PWM OUTPUT, many meanwell drivers accept PWM as a dimming input method, but then simply reduce the output current proportional to the duty cycle. For LEDs this is bad and is what results in the flickering effect when dimmed really low. Also with COBs the colour temperature and CRI is only rated at their nominal input current. I've seen this myself, testing a string of COBs on an ELG series driver, some COBs would turn bluer than others as the current dropped resulting in inconsistent colour temperature across the string.

    Relevant meanwell drivers:

    http://www.meanwell.com/productPdf.aspx?i=308
    http://www.meanwell.com/webapp/produ...x?prod=IDLV-25

    Each individual luminaire/COB has a secondary constant current driver in series with it to keep the input stable and prevent runaway.

    The primary driver, the IDLV, accepts two forms of dimming input. Either varying resistance, or 0-10v signal. The only 0-10v controller I've been able to find is the Qubino:

    http://qubino.com/products/flush-dimmer0-10v/

    Which appears to be sold as GOAP here in Australia.

    From what I can tell, this would require two z-wave devices to fully operate the lights. One, something like an Aeotec nano or HomeSeer HS-WS200+ to provide the on/off control to the driver, and a qubino 0-10v dimmer to provide the dimming.

    This doesn't seem like an efficient design let alone cost effective, plus configuration headaches. The Control4 switch however, provides the on off and dim all in one.

    For reasons I think a lot of us probably share, I don't want to go near ZigBee. And control4 seems insanely expensive to boot.

    Does anyone know of a comparative z-wave product to this Decora dimmer? Or can anyone suggest a more efficient alteration to the design that doesn't involve Triac or varying current dimming?

    Appreciate everyone's help. I'm new here, but it's a great community.
