WS503 Description
Overview
The WS503 is a LoRaWAN 3-gang smart wall switch for local and remote control of three lighting or appliance circuits. It uses a standard 86-type size, so it can replace a traditional switch directly while adding wireless control and energy insight.
Local & Remote Control
High-reliability relays switch three circuits independently, at the buttons or remotely over LoRaWAN. Class C operation keeps the switch always listening, so remote commands act instantly.
Energy Metering
Built-in metering reports voltage, current, power factor, active power and energy consumption, with overcurrent protection to guard connected loads.
D2D & Multicast
Milesight D2D lets the WS503 respond directly to other Milesight devices without a gateway, while multicast can switch many units at once for scenes and large sites.
Easy Retrofit
The 86-type body drops into existing pattress boxes. An ice-blue indicator makes all three gangs easy to find in the dark.
Setup
One-touch NFC configuration through the Milesight ToolBox app makes setup quick, with card emulation mode for fast deployment.
