Zemismart does the cheapest Zigbee/WiFi motors to automate roller blinds, but don't for 32mm tubes, common in the UK.

They provide adapters for 17 25 28mm, and there are some other models for 37 38mm.
The driver and guide ring parts are pretty standard and should be useful for any 32mm tube. Worth checking the gap width of your tube with the parts, which was 10mm in mine. So the gap is 10.5mm.
The fit wasn't perfect, and it could be tighter, but it's not noticeable in operation.
The bracket fixture serves to lock the motor's rotation, and be able to fit it in my original “dumb” roller brackets (my roller blinds were from 247 blinds). This saved me from replacing them with Zemismart ones, avoiding drilling new holes in the ceiling/wall. Unless your brackets have the same cross shape, you might need your own custom part for this.
