[APP] Fakro

Does anyone know how to get in touch with the developer of the Fakro app?

The link in the app page seems to be broken
(Fakro App for Homey | Homey 2)

I’m trying to work out how to add their z-wave windows and blinds to Homey, but still have the remote controls/wall switches work (which by default seem to use their own local z-wave network)

Cross posted, but likely lost, [here]
