There are a few products on the market, but the field of automated smart blinds/curtains lacks some serious innovation that I think Kasa TP-Link could fill.
What I would be looking for would be two styles. The first being a motor that takes a continuous feed of a fabric cord loop, metal/plastic chain loop, or one end of a string pull-cord and manipulates it in two directions. The second would be a twist-bar turner that could spin in both directions.
If this existed for Kasa I'd get 3 of the cord loop, 2 of the pull-cord, and 2 of the twist-bar styles.
Problem is that these exist, but none have quite the smart home integration that Kasa devices have, or are so expensive that my own setup would cost $1200, and that's rounding down. I think there's a spot in the market here.
