Setup and Installation
The Blindsmart Smart Curtain Motor is designed for easy installation on existing curtain tracks or rods without additional tools. It supports Roman poles (20-28mm), I-Rails (bottom width ≥ 12mm, ≤ 14mm, height ≥ 12mm), and U-Rails (bottom slotting width ≤ 8mm, width ≥ 15mm, height ≥ 7mm or width ≥ 15mm, height ≥ 12.7mm, 6.5mm < width < 8mm).
1. Charging the Motor
Before initial use, fully charge the motor using the provided USB cable. The 3000 mAh rechargeable battery provides up to 1-2 months of use on a single charge, depending on usage, track length, and curtain type.
2. Determining Curtain Opening Style
Consider your desired curtain movement:
- Single Open: If you want curtains to open from one side (e.g., left to right), one motor is sufficient.
- Double Open: If you want curtains to open from the center, two motors are required, installed oppositely.
