My understanding is that most roller blind tubes are hollow, so it’s just a case of buying a bound motor that sits inside them. There are also some that pull the beaded rope thingy but I’ve never used those

I have a zigbee2mqtt set up already, using a SLZB-06. Blinds worked fine with it, no fiddling required

I have used the zemismart ones. Essentially one end fits into the cross of the bracket and holds the frame. The motor inside the tube turns the small piece inside the tube.

In essence, the blind tube rotates around the blue tube you can see.
