WF96L features a linear isolation transformer for power supply, dual processors including an 8-bit MCU for local control and a 32-bit MCU for Wi-Fi functionality, providing strong anti-interference performance suitable for industrial environments. The controller is stable, reliable, and designed for continuous operation. It offers real-time synchronous feedback of remote output status and water level. The device can operate independently without Wi-Fi, supporting standalone water level control. Output on/off can be controlled remotely or manually when the set water level is not reached. Supports high-on and low-off mode for drainage control, or low-on and high-off mode for water replenishment, with optional time-limited control mode. Includes remote upper and lower water level alarm push notifications via app. The Tuya app displays current water level, priming water level, stop water level, upper and lower alarm levels, and time-limited operation duration. Features two-way outputs: one for water level control and one for anti-dry-burn protection. Offers four control modes: add water, pump water, time-limited water addition, and time-limited pumping. The main account can share device access with others; the device can only be linked to one main account.
