What is module ImportRemoteHA supposed to do?

[pz1]

I've played a bit with this module to see if I could import some commands from my production raspberry in the test raspberry. In the "List of devices not to import from remote side" I could only select local devices. But nothing happened after I has selected one or even all.
So what is this module supposed to do?

Got it finally working with v2.0.1-RC21. It does what I expected it to do.
