Milesight WS558 Switch Type LoRaWAN 8-Channel Smart Light Controller (EU868)

The Milesight WS558 Switch Type is an advanced LoRaWAN Smart Light Controller with eight independent dry-contact switching outputs, designed for intelligent lighting control and building automation in commercial, industrial and institutional facilities.

Developed for professional smart building applications, the WS558 enables centralized and individual control of up to eight separate lighting circuits or compatible electrical loads, offering flexible automation without requiring a dedicated controller for each circuit.

Unlike the WS558-LN version, the WS558 Switch Type features eight passive, potential-free switching contacts, making it suitable for applications where independent switching contacts are required rather than active voltage outputs.

Each output can be controlled individually, allowing lighting circuits, external contactors, compatible control inputs and other suitable electrical loads to be switched according to the requirements of the installation.

The device supports up to 10A per output for resistive loads and up to 5A per output for capacitive or inductive loads, subject to the electrical characteristics of the connected equipment and the manufacturer's installation requirements.

The WS558 Switch Type requires an external AC power supply of 100–240V AC, 50/60Hz for its own operation. Its dry-contact outputs do not independently supply operating voltage to the connected loads.

Communication is provided through LoRaWAN EU868, enabling remote switching and status monitoring through compatible LoRaWAN gateways, network servers and IoT management platforms.

The controller operates as a LoRaWAN Class C device, allowing it to receive remote control commands with low latency while continuously powered.

A particularly important feature is Milesight D2D communication, which enables direct interaction with compatible Milesight devices without requiring each switching command to pass through a LoRaWAN gateway or cloud platform.

This capability allows fast, local lighting automation based on occupancy, motion, ambient brightness or other conditions detected by compatible Milesight D2D devices.

For example, a Milesight WS202 PIR & Light Sensor can be configured to trigger lighting when motion is detected under suitable lighting conditions.

Similarly, compatible occupancy and presence sensors can be incorporated into building automation scenarios, subject to their supported D2D functions and firmware.

The WS558 also supports scheduled switching, delayed switching and multicast group control, enabling coordinated lighting operation across multiple rooms, floors or building zones.

With multicast functionality, several compatible controllers can receive the same command, simplifying the management of larger installations.

For local operation and commissioning, the WS558 features eight individual switching buttons and eight corresponding LED status indicators, allowing installers and maintenance personnel to operate and inspect each channel directly.

The device also includes a power indicator and a reset button.

Configuration can be performed using NFC technology through the Milesight ToolBox application, through the USB Type-C configuration interface, or remotely using supported LoRaWAN downlink commands.

The controller features overcurrent protection and alarm functions, providing additional safeguards for supported switching applications. These functions must not replace appropriately rated circuit breakers, fuses or other mandatory electrical protection devices.

The WS558 Switch Type is housed in a compact enclosure measuring 145 × 90 × 40 mm, suitable for DIN rail or wall mounting in protected indoor technical environments.

It operates over an ambient temperature range of −20°C to +60°C, making it suitable for a wide range of professional indoor installations.

The WS558 Switch Type is particularly suitable for commercial lighting automation, office buildings, warehouses, hotels, schools, healthcare facilities, retail stores and industrial premises.

Its combination of eight independent dry-contact outputs, LoRaWAN connectivity, Milesight D2D automation, scheduled switching and flexible installation makes it an efficient solution for modern smart building and Industrial IoT projects.

Important: The WS558 Switch Type does not measure voltage, current, active power, power factor or energy consumption in kWh. These electrical measurement functions are available on the WS558-LN version. The Switch Type should be selected when dry-contact switching is required.
