4.2.3 Multicast Settings
WS50x supports setting up several multicast groups to receive multicast commands from the network server, then users can use this feature to control devices in bulks. 1. Enable Multicast Group on WS50x, and set a unique multicast address and keys to distinguish other groups. You can also keep these settings by default.

Parameters	Description
Multicast Address	Unique 8-digit address to distinguish different multicast

groups.
| 32-digit key. Default values:

Multicast McNetSkey

| Multicast Group 1: 5572404C696E6B4C6F52613230313823 Multicast Group 2: 5572404C696E6B4C6F52613230313824

| Multicast Group 4: 5572404C696E6B4C6F52613230313826

32. Add a multicast group on the network server. Take Milesight UG6x gateway as an example, go to “Network Server -> Multicast Groups”, and click “Add” to add a multicast group.
Fill in the multicast group information the same as WS50x settings, and select the devices which you need to control, then click “Save”.
3. Go to “Network Server -> Packets”, select the multicast group and fill in the downlink command, click “Send”. The network server will broadcast the command to devices that belong to this multicast group.|
Note: ensure all devices’ application ports are the same.
4.3 General Settings

Parameters	Description
**** Reporting Interval	The interval of reporting switch status and

electrical parameters. Default: 20 mins, Range: 1 – 1080 mins
LED Indicator| Enable or disable the light of switch button. This will not affect the blinks when you hold on switch buttons to reset the device.
Power Consumption| Record the power consumption. If disabled, the device will stop recording and the power consumption value will stop updating.
When Power is Restored| If the device is powered off and restored, the device will change according to this parameter.
Button Lock| If enabled, all switch buttons will not be allowed to turn on/off or reset to factory default.
Change Password| Change the password for ToolBox App to write this device.

4.4 LoRa D2D Settings
Lora D2D protocol is developed by Milesight and used for connection among Milesight devices without a gateway. When Lora D2D setting is enabled, WS50x can work as the LoRa D2D agent device to receive commands from LoRa D2D controller devices.

Ensure the RX2 datarate and RX2 frequency in LoRaWAN settings are the same as the LoRa D2D controller device.
Enable the LoRa D2D feature, and define a unique LoRa D2D key to be the same as the setting in the LoRa D2D controller device. (Default LoRa D2D Key: 5572404C696E6B4C6F52613230313823)
Define a 2-byte hexadecimal control command (0x0000 to 0xffff) and command action. For example, you can configure a control command 12ff to turn on any button as below. WS50x supports at most 16 control commands.
These control commands can be configured in the LoRa D2D controller device. When LoRa D2D controller device is triggered, it will send the pre-defined control commands to control the switches of WS50x to on, off or inverse status.

4.5 Maintenance
4.5.1 Upgrade

Download firmware from www.milesight-iot.com to your smartphone.
Open ToolBox App and click “Browse” to import firmware and upgrade the device.

Note

Operation on ToolBox is not supported during the upgrade.
Only the Android version of ToolBox supports the upgrade feature.

4.5.2 Backup
WS50x supports configuration backup for easy and quick device configuration in bulk. Backup is allowed only for devices with the same model and LoRaWAN® frequency band.

Go to the “Template” page on the App and save current settings as a template. You can also edit the template file.
Select one template file that is saved in the smartphone and click “Write”, then attach it to another device to write the configuration.

Note: Slide the template item to the left to edit or delete it. Click the template to edit the configurations.
4.5.3 Reset to Factory Default
Please select one of the following methods to reset the device:
Via Hardware: Hold on the button for more than 10s until the button light blinks, this should ensure the button lock is disabled.
Via Toolbox App: Go to Device - > Maintenance to tap “Reset”, then attach a smartphone with an NFC area to the device to complete the reset.
