Using high- materials, the is guaranteed. Real-time synchronous feedback of remote output status and water levelIt can run independently without WIFI, and realize the function of single-machine control of water level. The on-off of one output can be controlled remotely or manually on site (when the set water level value is not reached)It can control drainage with high opening and low closing, or control water replenishment with low opening and high closing, or select time-limited control mode. Remote upper and lower water level alarm APP function. APP can display the current water level, water level, stop water level, upper and lower limit alarm water levelTwo outputs, one water level control, one anti-dry function. The main account can share the device with others, and the device can only be added under one main account (note that the alarm can only be realized if the device and the mobile phone are both online.
