I just received my HA Yellow box, a few days ago and now I am trying to integrate my thread network (2 AppleTVs as Border Router) so that I can see my EVE devices (they are thread only) in HomeAssistant.
I have installed the MultiProtocol Add-on and activated it.
This is what I see in the Thread Integration:
As per the Thread Matter & Thread: where we’re at I would expect to be able to make MyHome2 the Thread Network for HA, but I do not find a way to do that, i.e. the “Make Preferred Network” is missing.
I am relatively new to HA, so would appreciate easy to follow guidance 
Many thanks in advance!
