The WS50x offers remote control of devices from anywhere using a smartphone, bringing convenience and flexibility to users. It also features time-based ON/OFF controls, allowing users to automate their lighting based on customizable timers and schedules. Additionally, the device provides valuable insights into energy usage through power consumption measurement, aiding in smart energy management and cost savings.

The smart wall switch is designed with an LED status indicator and a screwless buckle, making it user-friendly and easy to install. It is available in different models to cater to varied wiring systems, including 3-Wire (with Neutral Wire) and 2-Wire (without Neutral Wire) configurations.
