Milesight WS101-868M — Smart Button in Scene and SOS variants
Milesight WS101-868M is a compact wireless LoRaWAN® button designed to launch scenes, trigger automation, remotely control devices and send events and alarms.
The manufacturer offers two device versions: PN: Scene with white button and PN: SOS with red button. The electronics and basic parameters of both variants remain the same, while the button colour makes it easier to match the device to a specific application.
WS101 recognises short, long and double press. Each action type can be used to invoke a different command, allowing several functions to be performed with a single physical button.
One button for scenes, automation and notifications
3 press types
Short Press, Long Press and Double Press can be assigned to different functions and scenes.
LoRaWAN® + D2D
WS101 can send events via LoRaWAN® or directly control compatible devices via Milesight D2D.
Compact design
The 50 × 50 × 18 mm enclosure and battery power allow the button to be installed virtually anywhere.
PN: Scene and PN: SOS
WS101 is available in two official variants identified by separate PN numbers.
Scene uses a white button and is intended primarily for triggering scenes, controlling devices and launching automation functions.
SOS has a red button, making it easy to recognise as a call-for-help button or a button for reporting a specific event.
Scene control and rapid event triggering
Short Press, Long Press and Double Press
WS101 has 1 external button with a diameter of 20 mmfunction.
The device distinguishes three basic action types: short press, long press and double press.
This allows several different commands to be assigned to one device; for example, a single press can launch a scene, a double press can switch a device off, and a long press can send another event to the system.
LED indicator and built-in buzzer
WS101 has built-in LED indicator providing information including device status and events.
Integrated buzzer provides additional audible confirmation, allowing the user to receive local feedback after a specific action is performed.
A separate Reset button is also located inside the enclosure.
Wireless communication in the EU868 band
Variant 868M supports, among others, the European frequency plan EU868, as well as IN865 and RU864.
The maximum transmit power at 868 MHz is 16 dBm, while receiver sensitivity reaches −137 dBm at 300 bpsfunction.
WS101 operates as a OTAA/ABP Class A, corresponding to the characteristics of a low-power battery-operated button that sends short messages after an action.
Up to 2 km in urban areas and 15 km in open space
The manufacturer specifies an indicative transmission range of up to 2 km in urban environments and for 15 km in field conditionsfunction.
Actual range depends on propagation conditions, mounting height, obstacles, LoRaWAN® gateway parameters and radio interference at the installation site.
Direct Control Without a Gateway
WS101 supports the Milesight D2D Controllerfunction.
Milesight D2D technology enables direct communication with compatible Milesight devices without routing every command through a LoRaWAN® gateway and higher-level platform.
The function can be used, for example, for immediate control of a wall switch, socket, controller or other D2D Agent device.
Commissioning and configuration via Milesight ToolBox
WS101 is equipped with NFC, allowing basic device configuration without a wired service interface.
The installer opens the Milesight ToolBox app on a compatible smartphone, activates NFC and brings the phone close to the device.
This makes both initial commissioning and subsequent button parameter changes easier.
ER14335 Li-SOCl₂ 1650 mAh battery
WS101 is powered by 1 ER14335 Li-SOCl₂ battery with a capacity of 1650 mAhfunction.
The manufacturer’s current product page declares over 5 years of operation with a reporting interval of 1080 minutes and 10 presses per day.
This value was determined under laboratory conditions and is indicative. Actual operating time depends, among other factors, on the number of presses, radio configuration, signal quality and temperature.
On a wall, 3M tape or lanyard
The compact battery-powered design allows WS101 to be installed without power wiring.
The manufacturer provides for mounting on a flat surface using screws or 3M tapefunction.
The device can also be carried on a lanyard, which is useful in applications requiring a mobile control or call button.
Call button with red marking
Version PN: SOS has a red button and can be used to send call or alarm events to the higher-level system.
Milesight clearly states that WS101 is intended to provide a convenient call or control function and should not be treated as the sole emergency-response toolfunction.
For safety-related applications, appropriate additional procedures and solutions compliant with the requirements of the specific installation should be used.
Compact 50 × 50 × 18 mm enclosure
WS101 has a small enclosure made of flame-retardant polycarbonatefunction.
Device dimensions are 50 × 50 × 18 mm, and weighs approximately 38,8 gfunction.
The IP30 rating indicates that it is intended primarily for indoor applications.
