Hi, how big does the roll get once the shades are all the way up? Does it become really big like a couple of inches in diameter or not too much? Thanks

Your sengled hub is a zigbee hub and your mentioned your got the zigbee smartwings variant. They should work together.

Can you manually use these if the motor goes out or are you SOL?

do they only extend to the full height purchased, or can you program them to unroll to a certain length?
