Yep! You can multiple groups of the same device type. One thing that’s a bummer is that at the present you can’t group multiple device types together in one group. So you can’t group house 1 cameras, and house 1 sensors and house 1 bulbs into “House 1”. You’ll need to do “#1 cameras”, #1 sensors" and so on. Wishlist alert! Go vote!
