Ok, i think i'll ask my last question- no, my question does NOT make sense!
Slowly learning matter, and it looks like the Matter device must support "multi-admin" mode (which, allegedly, virtually all Matter certified devices do).
Next, I need another Matter Controller / Hub. Seems like there's a million options out there.
Then- since my Flic hub now "owns" my matter devices- I need to "Share" the Matter device from the Flic Hub.
I can then commission the device on the additional Matter controller and control the device via either a FLIC button or another Matter device managed by this <future> second hub.
At least that's what I think needs to happen right now. Maybe after some more research I'll change my tune yet again!!
