Long story.
I’m having problems with 2x Qubino DC Flush Shutter ZMNHOD1 Z-Wave modules (EU) that I cannot seem to resolve.
I cannot get the Qubino modules to calibrate at all via the Vera hub and setting parameter 78 to a value of 1.
I have a roller blind with a Bofu ES2512-1.5/28 12V DC tubular motor (with motor limits set correctly) and it never goes fully up, down, up again to complete the “hub” calibration process on the Qubino module.
With a physical switch connected to the Qubino I can seemingly calibrate it that way instead using the wall switch OK.
However over time it seems to lose its calibration. The main issue is the blind sometimes just randomly stops when it’s meant to be going fully up or fully down, it decides nope, I’ve had enough now and just stops for no apparent reason.
Been on with Qubino support and done everything they have suggested with various parameter settings to no avail.
I’m sick of these Qubino DC Flush Shutter modules and really wished I’d bought a 240V motor and done it properly chasing the mains cable in the wall and used a Fibaro Roller Shutter module instead. I did that in my kitchen and its works perfectly.
But in the lounge I thought I’d make it “easier” and just surface mount a thin 12V DC cable up to the motor but it’s been nothing but trouble.
I’ve tried two different Qubino DC Flush Shutter ZMNHOD1 modules and they both behave the same way. I’ve also tried two different 12V power supplies.
I need up and down but also “dim” I need to be able to set the blind to a certain opened percentage, as its a Zebra roller blind.
There are no other EU Z-Wave alternatives on the market place.
Maybe I can use a Zigbee or more likely a WiFi shutter controller with my Vera Plus, any suggestions?
Or any way to use a 240V Fibaro Roller Shutter module with a 12V DC motor?
I am seriously thinking about pulling out the 12V DC motor and buying a new Dooya 240V tubular motor and Fibaro Roller Shutter module instead, if I can’t get it working reliably with the existing 12V DC motor.
The hub calibration is parameter 78 on the DC module.
It’s meant to go fully up, down and then up again however it never completes.
You can also calibrate it instead with an external switch connected. This does seem to work OK.
However over some time it loses its calibration.
And even when it seems to be calibrated it sometimes randomly just stops when it should not when moving fully up or down.
You can also instead configure a timing for motor movement with parameter 74, I’ve tried this as well and it doesn’t help.
Either these Qubino shutter modules are junk or they have serious problems with Vera.
Also on the DC motors there are only two wires to reverse polarity for up / down etc.
If you wire them exactly as per the Qubino instructions, then it’s wrong in the Vera GUI.
In the Vera GUI 0% is closed and 100% is opened.
Yet if you wired it following the Qubino instructions then when the blind is actually closed it shows as opened in the Vera GUI.
And when the blind is actually opened it shows as closed in the Vera GUI.
To correct it I had to reverse and swap round the two wires from the Qubino module to the DC motor.
