We don't have any plans - but it is one of the protocols on the wish list so maybe someone will tackle it. I'm hoping one of our European customers will tackle one of the more European friendly standards (I think KNX falls in this category).
Nothing special really - the Indigo side of the plugin is pretty straight-forward python, though an understanding of how Indigo works would be quite useful I suspect. The comm stuff to talk to the interface would be the more time consuming part to develop.
all that remains is writing a python plugin or use tcp out plugin to communicate with the daemon (eibd) . But for the statut request I do not know how to do it I'm not programmer if someone could write a plugin to support eib/Knx That will be amazing .
