I finally automated my curtains without drilling holes or replacing anything

The SwitchBot Curtain 3 is a retrofit motorized robot that attaches to existing curtain rods without drilling or replacing anything. It uses a high-torque motor to push/pull curtains along existing rails, supports solar charging via USB-C, integrates with Home Assistant, Apple Home, and Google Home via Matter through the SwitchBot Hub 2, and features a quiet drift mode (5 mm/s) and a tug-sensing feature. The author argues smart curtains are a more impactful smart home upgrade than smart bulbs due to real sunlight exposure benefits for circadian rhythm, and the device costs around $90 with a 10-minute setup.
