"Hey Google, open the curtains."
My fiancee's reaction was, "cannot just open it manually meh?". But the answer is the same answer the guys gave Penny in Big Bang Theory. "Because we can".
Bought the roller blinds cheap off Qoo10, and this AM43 Blinds Drive off Lazada, and ta-dah, smart roller blinds! A tap on your phone, a press of a button, or a quick voice command to Google or Siri, and the blinds can be raised or lowered, for when I prefer natural light.
