Velux or Fakro?

As far as I can make out, there is no way to directly control them over TCP (for example).

They need a Velux central controller, called a KLF200

Not quite true.
There is a Velux binding for the KLF200. But it´s limited to 32 scenes only.
Howvever - News are coming, Velux have made an new firmware for the KLF200, with a “real” API. This looks really promising.

Io-homecontrol / velux - something's in the bush

Hello guys, As you already have noticed VELUX has released a software update for KLF200. Unfortunately, we are still in the progress of setting up our systems to provide a pleasant experience for this, so we have some work to do. Currently we are not able to provide the changelogs for the updates in a way that we would like to do, but I am providing it here for you. But, the main change is that we have seen your interest in your use of the KLF200 and would like to provide you with a much bette…

Regard wether to select Velux or Fakro… Fakro have Z-wave windows. I havnt tried though. But at least this is a very good supported interface for working with openhab. I would contact Fakro and ask to get a communication module to test with a Z-wave controller. I dont know if these windows have been added to the database yet, but that should be the least.
