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:
https://github.com/domoticz/domoticz/issues/1683
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.
