Looking for homey app supported electric window opener

That’s what I’d hoped, and why I chose to replace 9 windows and 8 blinds, each with “Z-wave capability” in my house with Fakro instead of Velux a couple of years ago. But not only did none of the Z-Wave integration work, their support material is confusing and their support staff very indifferent to anyone who is not a property developer. Their position was completely unrealistic: “all you have to do is make our battery operated remoted control a secondary hub controller for your whole system, and pass the z-wave commands from one to another”. But if you have more than one remote control, what can do>
Apparently they said only one can be a secondary hub?

(BTW they also said I needed one power supply per blind, which is completely unnecessary/expensive).

If the app is truly revolutionary I will give it another go.
