Look into open source ZigBee bridges for home automation. A colleague of mine currently has a project going, which makes her Raspberry Pi act like a bridge and it talks to other home automation stuff via ZigBee.
Then you can use stuff like this to control the motor of the curtain.
Great thing is that you can handle your complete home automation like this, but it might be harder and expensive to setup than just using proprietary bridges and actors.
A fork is effectively your own repo, so you can do with that as you please. Afaik MIT license doesn’t hinder you from removing anything.
