You are making assumption I want to wake up that early.
Quite opposite - I’m searching for way to completely black out the room since kids will wake up with slightest shred of light, far before daycare starts. And I’m not even living if far lats.
But yeah I still want them for convenience. Problem is I don’t want cables dangling around curtains and battery options are limited.
This comment makes no sense. You choose when you want your automated blinds to open, if you don't want to wake up early, just don't set them to open early?
Yes they can, the thing you're looking for is literally called black-out blinds. Installed properly, they don't let any light in even when it's high noon outside.
