Tahoma for integration with Velux: Offline possible?


I have velux roof windows including shutter, everything controlled via io homecontrol.

I integrated them with the Velux KLF200 Gateway, but it has some disadvantages. The biggest disadvantage ist, that there is no return channel, so no position indication possible.

I read that this should be possible via Tahoma Premium, but I am not sure if this is possible to do without cloud access.

Any ideas?`
