Milesight WS502-868M LoRaWAN Smart Wall Switch - 3 Wires
WS502-2W-868M
WS502 is a LoRaWAN smart wall switch for local and remote control of lights and electrical appliances.
It is widely used for wireless control of indoor lights, fans, heaters, machines, and so on.
It adopts the standard size of most kinds of international wall switches, so it can directly replace traditional wall switches. In the WS50x series of intelligent controllers, WS502 is a dual model with two push buttons.
WS502 can be monitored and controlled through a website or the mobile app and can also be activated by other Milesight sensors because it supports the Milesight LoRa D2D communication protocol to establish communication between devices without going through the gateway.
Smart Wall Switch WS502
Wall switch? yes, but powered by LoRaWAN
This intelligent switch allows traditional mechanical use, and thanks to its LoRaWAN wireless communication, the possibilities are endless. You can control from anywhere whatever you connect to the wall switch. Traditionally it will be a light bulb, but it can be any electrical device you attach. You need to have a gateway nearby to provide coverage.

Various types
With LED status indicator, screwless buckle, and 3-wire circuit.
Remote ON/OFF + Time based ON/OFF
Remote control from a smartphone anywhere. Set timers and schedules to make lights function automatically.
Milesight D2D communication
Milesight D2D (Device to Device) protocol featuring LoRa enables communication among different Milesight LoRaWAN® node devices without a LoRaWAN® gateway. Meanwhile, WS50x can both work as Controller or Agent (first image).
Power consumption measurement
The power consumption measurement and flexible schedule settings would help to save power and lower electric bills.
LoRaWAN based
Compatible with industry-standard LoRaWAN® gateways
Milesight IoT Cloud - Compatible with Milesight IoT Cloud and control the switch at your fingertips.
Easy Configuration with a mobile app via NFC
Installation Considerations
There are two types of switches depending on whether they have a neutral wire or not (4 wires/3 wires). This product is the 3 wires variant (L, L1, L2). For the 4 wires variant (N, L, L1, L2) go to WS502-868M-3W.
We recommend installation with neutral wire for safety reasons. The problem is that traditional switch installations do not have a neutral wire because it is not necessary, at least in Spain. The solution is to bring a neutral from the nearest junction box. In case of wanting to use (or not having more choice) the installation without neutral, it is necessary to add a resistor in parallel to the bulb that feeds to eliminate the flicker that is produced. This flickering is a consequence of the power supply of the electronics of the wall switch feeding the bulb or bulbs it controls. This is eliminated with a capacitor. One drawback to being aware of when using this method is that the capacitors make a small humming noise that in total silence conditions can be annoying. Ask us if you have any questions!
