Milesight WS502-868M – Smart 3-Gang LoRaWAN® Wall Switch for Lighting and Device Automation

The Milesight WS502-868M is a three-channel smart wall switch designed for wireless lighting and appliance control via LoRaWAN® technology. It supports manual operation or remote management through the Milesight IoT Cloud or mobile application, allowing users to easily switch and automate devices from anywhere. With standard form factors (86 Type / 120 Type), the WS502 can directly replace most traditional wall switches (neutral wire required).

Equipped with a high-reliability relay, the WS502 ensures stable switching performance for both local and remote operations. It also provides real-time electrical measurements, including voltage, current, power factor, active power, and energy consumption, while integrated overcurrent and overload protection ensures device safety.

With Milesight D2D (Device-to-Device) communication, the WS502 can interact directly with other Milesight devices without the need for a gateway, ensuring ultra-low latency. It also supports multicast control, allowing users to manage multiple switches or appliances simultaneously.

The WS502 features an ice-blue indicator light, making it easy to locate and operate even in dark environments. Built from flame-retardant UL94 V0 polycarbonate, it combines durability with a modern design. Configuration is simple via NFC or downlink, and installation is straightforward using standard wall mounting methods.

Fully compatible with Milesight IoT Cloud, the Milesight Development Platform, and all standard LoRaWAN® gateways, the WS502 is the perfect solution for smart lighting, energy management, and remote control in homes, offices, hotels, museums, and commercial facilities.
