Developed using Tuya Smart Platform WR3 SOC solution. WR3 is a low-power embedded Wi-Fi module developed by Tuya Smart. It consists of a highly integrated wireless radio frequency chip RTL8710BN and an external flash chip. It has built-in Wi-Fi network protocol stack and rich library functions.

Function:
1. Bi-directional power supply, can be powered directly by AC 220V power supply, or via micro USB;

2. Connect to home power supply and can set inching/self-locking;

3.1-4 channels are independently controlled, can be connected to the Tuya platform in scene linkage, and support voice assistants such as Xiaodu.

user terminal:

The actual measured standby power consumption is about 0.05A, and the four-way full pull-in is 0.4A.
