2. Remote APP Control: Pair with the Tuya Smart or Smart Life app to remotely switch connected devices on or off and monitor running status from anywhere, at any time.

7. Power-Failure Memory: Retains the device state before a power interruption. Configure the module to restore to on, off, or the last-used state when power returns.
8. 3 Flexible Wiring Methods: Connect directly to a device (no physical switch needed), install behind an existing single-control switch, or wire in for dual-control (2-way) switching — all without removing or replacing your current switch panel.
