Advanced Settings

Calibration Settings

WS203 supports numerical calibration of the temperature and humidity value. Go to Device > Settings  > Calibration Settings of ToolBox App to set the calibration value, the device will add calibration value to the current value and upload the final value.

Threshold Settings
Go to Device > Settings > Threshold Settings of ToolBox App to enable the threshold settings and input the temperature threshold. If the temperature threshold is triggered, the device will upload the alarm packet once instantly and collect the temperature & humidity data as collect interval until the
alarm releases.

Data Storage
WS203 supports storing 1000 data records locally and exports data via ToolBox App. The device will record the data according to the reporting interval even not joining the network.

1. Go to Device > Status of ToolBox App to sync the device time.
   

2. Go to Device > Setting > General Settings to enable the data storage feature.
   

3. Go to Device > Maintenance of ToolBox App, click Export, then select the data time range and click Confirm to export data. The maximum export data period on ToolBox App is 14 days.

4. Click Export Record to find the export file records.
   
   Note: Slide the file record to the left to delete the record.

5. Click Data Cleaning to clear all stored data inside the device if necessary.
   

Data Retransmission
WS203 supports data retransmission to ensure the network server can get all data even if the network is down for some time. There are two ways to get the lost data:

• Network server sends downlink commands to enquire the historical data for specifying time range, refer to section 5.4;
• When network is down and no response from LinkCheckReq MAC packets for a period of time, the device will record the time of disconnection form the network and retransmit the lost data after the device is reconnected to the network.

Here are the steps of data retransmission:

1. Go to Device > Setting > General Settings to enable data storage feature and data retransmission feature.
   

2. Go to Device > Setting > LoRaWAN Settings to enable rejoin mode feature and set the number of packets sent. Take below as example, the device will send Link Check Req MAC packets to the network server regularly to check if the network is disconnected; if there is no response for 8+1 times, the join status will change to de-active and the device will record a data lost time point (the time to join the network).
   

3. After the network connected back, the device will send the lost data from the point in time when the data was lost according to the data re-transmission reporting interval.

Note:

1. If the device is rebooted or re-powered when data retransmission is not completed, the device will re-send interrupted retransmission data again after the device is reconnected back to the network.
2. If the network is disconnected again during data retransmission, the device will only send the latest disconnection data.
3. The retransmission data format is started with “20ce”, please refer to section 5.4.
4. Data retransmission will increase the uplinks and shorten the battery life.

Milesight D2D Settings
Milesight D2D protocol is developed by Milesight and used for setting up transmission among Milesight devices without a gateway. When the Milesight D2D setting is enabled, WS203 can work as a Milesight D2D controller to send control commands to trigger Milesight D2D agent devices.

1. Configure RX2 data rate and RX2 frequency in LORaWAN® settings, it is suggested to change the default value if there are many LoRaWAN® devices around.
2. Go to Device > Settings > D2D Settings to enable D2D function and configure the D2D settings.
   

agentdevices. Default value: 5572404C696E6B4C6F52613230313823
Status Condition| When WS203 detects one or more of the below statuses, it will send the control command to the corresponding Milesight D2D agent devices:l   Occupied & Temperature threshold triggeredl   Occupied (PIR)l Vacant (PIR)l   Temperature threshold triggeredl   Temperature threshold is liftedNote: for temperature threshold conditions, please enable and configure
| the temperature threshold feature under Threshold Settings.
Control command| Define a 2-byte hexadecimal control command (0x0000 to 0xffff).
LoRa Uplink| If enabled, a LoRaWAN® uplink packet that contains the PIR status or temperature alarm will be sent to gateway after the Milesight D2D controlcommand is sent.
Control Time/min1| After receiving commands from WS203, Milesight D2D agent devices will take corresponding actions for this duration.Default: 5 mins, Range: 1 – 1440 mins

Maintenance

Backup
WS203 supports backup templates for easy and quick configuring devices in bulk. The backup feature is only for devices with the same model and LoRaWAN® frequency band.

1. Go to Template page on the App and save the current settings as a template. The saved templates are also editable.
   

2. Select one saved template and click Write, then attach the smartphone to another device via NFC to reuse the template
   

Note: Slide the template item to the left to edit or delete the template. Click the template to edit the configurations.

This feature is under development on Milesight D2D agent devices.

Upgrade

1. Download firmware from the Milesight website to your smartphone.
2. Go to Device > Maintenance of ToolBox App, tap Browse to import firmware and upgrade the device.

Note:

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

Reset to Factory Default

WS203 supports two methods to reset the device which are as following:
Via Hardware: Press and hold the power button for more than 10s until the LED indicator blinks quickly.
Via ToolBox App: Go to Device > Maintenance to tap Reset, then attach the smartphone to the device via NFC to complete the reset.

Installation

Installation Note:

1. Adjust the installation direction according to the detection area requirement.
2. Ensure the detection area does not have moving objects like waving trees and fans.
3. Ensure the detection area is not blocked by curtains or barriers.
4. Do not expose the device to direct infrared (including sunlight, light, etc.), or the PIR detection will be affected.
5. The recommended installation location is 2 m in height on the wall with the half PIR cover to avoid room light inference.
6. Avoid the device to face a transparent plate (like glass) within 5m since the PIR will detect through it.

PIR Cover Installation:
Take off the front cover of the device, then select the PIR cover as required and put it on the PIR sensor with groove alignment. The adjustable angle of every groove is 30°.

PIR cover reference guidance(wall mount and installation height=2m):

| Maximum: 120 ° Horizontal, 50 ° Vertical, 6 mRecommend: 98 ° Horizontal, 44.4° Vertical, 5 m
| Maximum: 38 ° Horizontal, 50 ° Vertical, 6 mRecommend: 38 ° Horizontal, 44.4° Vertical, 5 m
| Maximum: 38 ° Horizontal, 100 ° Vertical, 6 mRecommend: 38 ° Horizontal, 88.8° Vertical, 5 m
| Maximum : 120 ° Horizontal, 100 ° Vertical, 6 mRecommend: 98 ° Horizontal, 88.8° Vertical, 5 m
| Support to be tailored as required

Fixed by 3M Tape:
Attach 3M tape to the back of the sensor, then tear the other side and place it on a flat surface.
Please adjust the installation direction according to the detection area.

Note:

1. Since the default 3M tape has a high viscosity, please tear the device down via a screwdriver.
2. If it is necessary to tear the device down easily, please divide the 3M tape into several parts and only tear one part to the device.
   

Fixed by Mounting Kits

1. Take off the front cover of the device, then fix the wall plugs to a flat surface according to the device mounting holes. Finally, secure the device to the wall plugs using screws. Please adjust the installation direction according to the detection area.
2. Restore the front cover back to the device.
