Qubino Flush RGBW Dimmer ZMNHWD1 Z-Wave Plus

[niceandeasy]

Nice gadget: Qubino Flush RGBW Dimmer ZMNHWD1 Z-Wave Plus
4 PWM outputs: max 13 amps total or max 8 amps if only one output is used. 12V or 24V. That would be a LOT of LEDs.
4 switch inputs or analog voltage inputs or 100K potmeter inputs. Sweet.
5 pre-defined scenes, 16.7M possible colours
Also good for controlling fans and/or halogen bulbs.
PWM-freq 488Hz.
I like the specs and sales pitch of this gadget.

But does anyone know if this thing is Domoticz-compatible?
Can it function as an RGBW device in Domoticz?
Can it function as an RGB device in Domoticz and with an extra device for other use?
Can it function as 4 separate devices?
What can Domoticz do with the inputs?
What could be done when direct-associate these inputs to other zwave devices?

Please let me know if you have good or bad experiences with this gadget.

I have one since March 2017 as RGBW without switches to the inputs.

But does anyone know if this thing is Domoticz-compatible?
Yep

Can it function as an RGBW device in Domoticz?
Yes

Can it function as an RGB device in Domoticz and with an extra device for other use?
Dono

Can it function as 4 separate devices?
Never tried

What can Domoticz do with the inputs?
Dono

What could be done when direct-associate these inputs to other zwave devices?

My shipment of ZMHNHWD1 H1S1P1 arrived, today. But... Hmm.. it is disappointing...

For testing purposes, I connected it to a 12V500mA stabilized adapter. Also, a short piece of RGB and a bit of warmwhite led-strip was attached. Inclusion went well. I got a dimmer device and an RGBW device in Domoticz. These two devices followed eachother and acted the same. If you would use the dimmer, it would turn on and dim in the last colour.

The colour control was a big disappointment, because the Domoticz RGBW-switch is not well implemented. Saturation is being ignored. If you go above approx. 80% saturation (to the white side on the colourpicker), the RGB leds simply shut off and the whites come on. If you go below that approx. 80%, The whites turn off and the RGB takes over, but it does so with no saturation at all. So, it is impossible to select soft colours.

Because of this, and because the fact that it spawned just an RGBW controller and one dimmer, it cannot be used for PWM-controlling 4 loads independently

The inputs. They are a bit hard to figure out what they do. I did not have 4 discrete switches at hand, so I used a paperclip. While doing that, it Domoticz did not connect extra devices. There is just one association group in the zwave network settings for this thing.
So, I was poking along with my paperclip. What actually happens, depends on the zwave settings of the device. Settings are only half working. The built-in pre-defined scenes are boring. And it seems that they can only be selected by changing settings. Not practical.

Then, I accidentally bridged a switch input to the +12V-supply, instead of ground, with my paperclip. Bad choice. It sparked a bit, the unit got a bit warm and some smell eminated from it. I disconnected the adapter, waited a bit, connected it again. The LEDs flashed once. And the unit got warmer. The switches in Domoticz got red... I unplugged it again. I think I killed it. After a cooldown, I tried again. The unit now draws 270mA, no LEDs on. At least, my powersupply is still okay. In this state, it did not come online anymore in Domoticz before it got so warm that the smell started again.

The unit's user manual that it has 100kOhm inputs. If that would be true, this unit would not damage and would not spark if you would connect it to the +12V supply. Or, are they trying to say that you can connect these inputs to ground via switches or via 100kOhm potentiometers? Sadly, the manual does not depict how to connect potentiometers.

The thing is fried. Might as well open it. The part that got hot is the main microcontroller, so, the thing is definately fried.
On some web sites, this thing is advertised to be able to control fans. Well... the circuit board has unpopulated spots for back-EMF-protection-diodes. So, the only protection is the internal diode of the mosfet. Small brushless computer-fans are probably okay but don't use this thing to control inductive loads. By the way, hard to believe that those tiny little SMD mosfets can do 8amps.

Well,
I ordered two, so I have one left. Need to find out how not to kill that one as well...

Google led me to this:

I can say that this issue is "fixed", in the sense of that it kinda works as intended, I guess. ..at least, .. in the current stable version.
It is fixed with the faulty Domoticz RGBW device. I'd rather have 4 separate dimmers so I can truly use it as an RGBW dimmer.
So, if you're reading this, Gizmocus, if you need some more testing to be done with this device, let me know.
By the way, can you give us 4 dimmers as an extra? As an extra to what it is now, one dimmer, one RGBW dimmer.

Somebody asked me by PM, how to set the color by JSON commands.
Well, that is right here: http://www.domoticz.com/wiki/Domoticz_A ... brightness
Two commands are in this section, one for HSB color control, without saturation, and a new one, for RRGGBB.

Using the latter on my Qubino, we still get odd behavior when we set a near-white color, for example, 20201F. The Qubino will light its white LEDs, instead of mixing the desired color with red/green/blue.

I'm currently using my left-over Qubino for controlling an RGBW strip. Which works fairly well, within the limitations stated earlier.

Question: How can I set the colour?
I'm a newby and can only do Blockly... but if you give me some Lua or DZVents lines I think I can modify them for my needs. Just I need a hint...

Thanks!
