Qubino Flush Shutter DC: pairing problems and Flow question

Welcome to this community forum, sorry to mention this but on me, you come in as a bit negative but OK.

Qubino devices are not less reliable than other brands and can very easily be added (included) by keeping Homey and the device close together as mentioned in many descriptions.
First, remove (exclude) them (even when they have never been included before) via Homey Developer Tools image
Then un-power the device, go to the Devices include-page (+ in the upper corner, choose Homey, choose Z-Wave, press Install, then power-up the device again, follow the screen instructions.
After inclusion, Homey and the device can be separated.

For opening and closing at a specific time/day you can use the Alarm settings that you can find on the page after pressing More (second item)
