What It Does

Built for safety.

A compact LoRaWAN panic button in a red SOS housing. Single press, double press and long press each trigger a separate configurable alert — enabling SOS, task completion and scene control from one device. Battery-powered for over five years, with Milesight D2D for direct device control without a gateway. LoRaWAN decoder: Milesight WS101 payload decoder & codec (GitHub)

Highlights

Three actions, one button

Short press, double press and long press each trigger a separate configured alert, so a single device can cover SOS, task confirmation and room-state signalling without multiple units.

Five-plus years, no wiring

Battery-powered and surface-mounted with screws, 3M tape or a lanyard, the WS101 can be positioned anywhere a member of staff or resident might need to raise an alert — no electrician required.

Works without a gateway

Milesight D2D allows the button to control a door lock, alarm panel or indicator light directly, peer-to-peer, so the panic response does not depend solely on network availability.

Complete The Setup

You will also need a gateway.
