Multi-Function Lighting Controller with Two Versions
Control up to 8 Lighting Circuits
More lights connected to one controller, fewer switch panels, lower wiring costs
Centralized control of 8 lighting circuits and each circuit can be controlled respectively
Remote & Time-Based ON/OFF
Remote control from a smartphone anywhere
Set timers and schedules to make lights function automatically
Up to 18 hours turn-off delay
Multiple Scenes Based on Milesight D2D Communication
Milesight D2D protocol featuring LoRa enables the communication among different Milesight LoRaWAN® node devices without a LoRaWAN® gateway
Easy to Test the Light Status
WS558 supports local switch button control and allows to test the light status without networking after powering up the device
Power Consumption Measurement
The power consumption measurement and flexible schedule settings would help to save power and lower electric bills. (Only LN Type)
Overcurrent Protection
The overcurrent protection prevents the connected lights and the smart controller itself from damage of short circuit and overload
Power-Off Memory Function
In case of any power failure, the present settings will be saved and WS558 will resume to previous operating status after power has been restored

You May Want to Know
?What role does a smart light controller play in a smart lighting system
A smart light controller enhances smart lighting by enabling remote access, automation, centralized management, integration, and energy efficiency. It allows users to centrally control lighting and automate schedules based on triggers. It can integrate with other systems for coordinated scenarios and optimize energy efficiency.
?Can I control multiple lights with one smart light controller
Yes, you can control multiple lights with one smart light controller. For example, Milesight Smart Light Controller WS558 can handle up to eight separate circuits—each can be controlled respectively. It significantly reduces wiring costs and simplifies installation in various settings such as offices, shopping malls, and schools. Additionally, it supports both remote control and time-based scheduling, allowing users to turn lights on or off via a smartphone app or set timers for automatic operation.
?What are the benefits of using smart light controllers for commercial buildings
Smart light controllers benefit commercial buildings by enhancing energy efficiency, operational flexibility, and user comfort. They reduce lighting costs by 35-70% through occupancy sensing, daylight harvesting, and scheduling. Central management simplifies wiring and lighting control in large spaces, while remote and timer-based features prevent energy waste. Additionally, Milesight Smart Light Controller WS558 is equipped with overcurrent protection to safeguard against overloads and short circuits, enhancing the safety of the lighting system and reducing maintenance costs.
?Why retrofit legacy buildings with smart lighting control
Retrofitting legacy buildings with smart lighting improves energy efficiency, occupant comfort, and operational control. This upgrade can reduce energy consumption significantly through occupancy-based and daylight dimming adjustments. Integrating smart lighting with building management systems enhances overall efficiency, while features like circadian lighting improve occupant well-being. The ROI is significant, with energy savings boosting property value. Smart lighting also supports sustainability goals by reducing carbon footprints and can help buildings earn green certifications.
?What are the key features to look for in a smart light controller for commercial use
When selecting a smart lighting controller for commercial use, prioritize key features such as sensor integration (occupancy and motion sensors), remote control via mobile apps, and customizable settings (scenes and scheduling). Ensure compatibility with building management systems (BMS) for seamless integration and scalability for future needs. These features collectively enhance efficiency, reduce costs, and improve user experience.
