The original listing describes a Bluetooth motor for adjusting plantation shutters and Venetian blind slats. It is limited to the listed aluminium, PVC and wood plantation-shutter applications and is not intended for all roller blinds. Check the mechanism and mounting fit before ordering.
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. Without a Bluetooth gateway, operation is limited to opening, closing and stopping the slats; smart-home linkage is not available.
A compatible Bluetooth gateway is required for the described voice control, automation with other Tuya devices and control while away from home. The original Q&A states that timer and countdown functions are not supported.
The listing describes RF control and limit-position setup. Confirm the supplied transmitter, accessories and instructions. It also describes USB charging with a solar panel as an auxiliary charging accessory and recommends using it with a power plug; do not treat the solar panel as an assured sole power source. Adhesive or screw mounting is described in the original listing.
