I've got a blind motor controlled from two digital outputs (one for up, one for down). It's connected to the miniserver using 2L+N+E cable. We bought it from
https://newblinds.co.uk/electric-roller-blinds (select your blind, then select 230VAC relay operation, and we've got the "
Newblinds - Quiet Relay (4-core)" motor.
We've done similar with curtains, although we bought them elsewhere.
Cheers,
Ewan
