Smart Portable Socket

The Milesight WS52x Series is a series of smart wall switches with advanced features to offer wireless control of lighting, appliances, and equipment in contemporary buildings. Driven by LoRaWAN® technology, the WS52x switches allow real-time remote control, scheduling flexibility, and energy-saving automation—all without the requirement of new wiring or complicated installation.

Comes in single-gang (WS521), double-gang (WS522), and triple-gang (WS523) options, the series meets different control requirements from basic lighting control to multi-device management in offices, hotels, schools, and factories. The switches run on common 100-240V AC power, carry loads of up to 10A per channel, and communicate wirelessly using LoRaWAN® Class C, interoperable with leading network servers and IoT platforms.

Key Features:

• LoRaWAN® Class C powered wireless smart switch (EU868/US915/AS923 frequency plans supported)

• 1-gang (WS521), 2-gang (WS522), and 3-gang (WS523) versions available

• Manual switching and wireless remote control through IoT platforms are supported

• Standard input: 100-240V AC; maximum load: 10A per channel

• Long-distance communication (up to 15 km in rural environments) with low power consumption

• Simple retrofit installation—no rewiring necessary for existing electrical systems

• Flexible scheduling and automation rules for energy savings

• CE, FCC, and RoHS certified for worldwide compliance

• Control-oriented design (no energy monitoring, purely switching control)

Unique Benefits:

Seamless retrofitting: Replace traditional wall switches to provide smart control without ripping walls or installing new wires. Perfect for retrofitting existing buildings to IoT control.

Energy efficiency: Program lighting and appliance use to cut down on energy waste in offices, hotels, or industrial complexes.

Long-range flexibility: LoRaWAN's wide range makes WS52x a perfect fit for big spaces such as factories and campuses where Wi-Fi or Zigbee coverage is poor.

Dual control options: Users can control switches physically or remotely using Milesight IoT Cloud, The Things Stack, or other LoRaWAN platforms.

Scalable solution: Select from 1-, 2-, or 3-gang configurations to upgrade smart small rooms or big halls, making upgrades easy.

Broad compatibility: Compatible with smart lighting, ceiling fans, exhaust fans, and other non-dimmable electric loads.

Target Use Cases:

Commercial properties: Schedule and monitor lighting, fans, and appliances in office spaces, meeting rooms, and reception areas wirelessly.

Hospitality sector: Automate guest room lights and save energy in hotels, resorts, and conference centers.

Educational facilities: Regulate classroom and auditorium lighting, providing the most efficient energy consumption across campuses.

Factories and warehouses: Control lights and ventilation units remotely to improve performance and reduce manual intervention.

Smart homes: Retrofit old wall switches to allow smart control of home lighting and devices, without the expense of rewiring.

With trustworthy LoRaWAN connectivity, easy deployment flexibility, and uncomplicated retrofitting, the Milesight WS52x Series gives building managers, facility operators, and homeowners the ability to implement smarter, more efficient control solutions. Whether retrofitting an office space, a factory environment, or a hotel chain, the WS52x provides a practical, scalable route to smart building automation.
