Somfy Blinds

Opinions on Somfy blinds? Specifically,

  1. can I create automations that will send the blinds to 1/2 or 3/4 open…. Or is it 100% open or closed only?
  2. Would these be Custom DH or ST standard?
  3. If Custom DH, will I experience issues once the IDE is gone?
  4. I’m assuming I’ll have no issues controlling via WebCoRE pistons(?).
    Thanks for any help!
