The original listing describes a Bluetooth chain-drive motor for looped bead-chain roller blinds or shades, with app and local touch controls. Confirm the chain size, matching drive gear, blind load and mounting fit before ordering; compatibility with every chain or blind is not established.
According to the original instructions, basic point-to-point Smart Life app control requires the phone's Bluetooth to be on and does not require a gateway or network. The described voice control, away-from-home control, timing and automation require a compatible Bluetooth gateway. App and motor controls are described for setting upper and lower limits; follow the supplied instructions.
US Adapter, UK Adapter, EU Adapter and AU Adapter are separate catalogue options. Confirm the actual supplied adapter's plug, input and output ratings before use. The regional option label alone does not establish electrical suitability, and charger input, battery voltage and stalled-motor current are different specifications.
The original listing describes a built-in rechargeable battery, an adapter and drive gears. Check the package contents and supplied manual. Installation time, universal compatibility and standby performance are not guaranteed.
