Hello people, I could use some help on configurating a Qubino zmnhod1 on Homey v1.5.12. and the Qubino app v2.0.6. The zmnhod1 is paired with Homey. I want to use the zmnhod1 with a Velux SML shutter (DC). The shutter works by reversing polarity. I connected two switched to I1 and I2. When i press either swich and measure the pins of the motor i measure either +24V or -24V for a second and then it’s gone. When i measure the switches i get a constant 24V. And when i connect the powersuply directly to the shutter it shuts and opens (with the polarity reversed). I figured it might be a calibration issue. The manual says to either switch I1 and I2 or by setting parameter 78 to value 1. This is where i am stuck. Can someone help me with this problem or please explain how i can set parameter 78 to value 1 in Homey? Thank you, Jeroen ---

I don’t own the device but there must be a setting in the device called “expert parameters”? Like clicking on the wrench icon on the device page and scroll to the bottom? ---

Thank you for the quick reply. There is an expert parameter option, but unfortionally i don’t know how to enter the parameter 78 and value. ---

Well, something like 78,1,1? Size should also be in the manual me guess. ---

My motors have limit switches so I set the Up/Down moving time of motor to 0 and then used the Start Calibration button (I’m using the Homey Preview app). If you don’t have limit switches then I think you need to set the Up/Down moving time of motor to 0 then move the motor to the bottom / closed position by holding down the switch and then set the time it takes to move full travel. ---
