Overview
WS503 overview
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.

Applications
WS503 applications
Smart Buildings
Offices and common areas switch three lighting circuits and track energy use. Multicast control manages many switches across floors at once.
Hospitality
Hotels automate multi-zone room lighting and integrate with scenes. The familiar switch design keeps operation intuitive for guests.
Museums
Galleries control several lighting zones from one panel while monitoring consumption. D2D enables instant local automation without a gateway nearby.
Homes
Homes gain remote and scheduled control of three circuits with energy insight. LoRaWAN gives wide, low-power coverage with minimal wiring.
