Use Aqara E1 Drivers but directly mounted to the curtain. Rip of the roller chain and make any curtain motorized on a budget.
Works perfectly with IKEA's 180 cm wide and heavy fabric sun blockers. Daily motion, needs a recharge every 8 weeks or so, which can be made when the motor still is in the cradle.
UPDATE: My curtains go down/up once every day. I haven't charged them for 2½ months and still 40 % battery left.
Simple assembly. The other end of the curtain will use the standard bracket with the pin. Press the motor into the tube, stick the pin end in and drop the motor down in the cradle.
