Moving "Echo" Device in different home

Hello, I can’t find a way to move my Echo Spot from my main home to the other house.
I have 2 smartthings hubs one for each house I also have another Echo dot witch is added to my main house. I tried moving it from The Groovy IDE but without any success I’ve only managed to redirect the Echo Spot to the other hub, but it still doesn’t shows up in the other location.
Any suggests?
