Confirmed Mode| If the device does not receive ACK packet from network server, it will resend data once.
Rejoin Mode| Reporting interval ≤ 35 mins: the device will send a specific number of LinkCheckReq MAC packets to the network server every reporting interval or every double reporting interval to validate connectivity; If there is no response, the device will re-join the network.
Reporting interval > 35 mins: the device will send a specific number of LinkCheckReq MAC packets to the network server every reporting interval to validate connectivity; If there is no response, the device will re-join the network.
Set the number of packets sent| When the rejoin mode is enabled, set the number of LinkCheckReq packets to send.
Note: the actual sending number is Set the number of packet sent + 1.
ADR Mode| Allow network server to adjust datarate of the device.
Tx Power| Transmit power of device.

Note:

1. Please contact sales for device EUI list if there are many units.
2. Please contact sales if you need random App keys before purchase.
3. Select OTAA mode if you use Milesight IoT Cloud to manage devices.

3.3 Basic Settings

battery level to network server. Default: 10 mins, Range: 1-1080 mins.
Restoration of Power| If the device loses power and returns to power supply, the device will be on or off according to this parameter.
Rainfall Accumulation Phase
(WTS506 Only)| After the rainfall accumulates up to this time range or up to 1000 mm, it will clear and re-count the accumulated rainfall value.
There are two parameters to set the time range, range: 0~48 h
Data Storage| Disable or enable reporting data storage locally.
Data Retransmission| Disable or enable data retransmission.
Change Password| Change the password for ToolBox App to write the device and ToolBox software to configure this device.

3.4 Advanced Settings
3.4.1 Threshold Settings
If the threshold is triggered, the device will upload the alarm packet once and collect the data at the specified interval. 

3.4.2 Data Storage
WTS series supports storing more than 19,000 data records locally and exports data via ToolBox App or ToolBox software. The device will record the data according to reporting interval even not joining to network.

1. Sync the time via ToolBox or downlink commands.

2. Enable data storage feature.

3. Go to Maintenance > Basic of ToolBox software or Device > Maintenance of ToolBox App, click Export, then select the data time period and click Save to export data.
   Note: Toolbox App can only export last 14 days’ data. If you need to export more data, please use ToolBox software.

4. Click Clear of ToolBox software or Data Cleaning of ToolBox App to clear all stored data if necessary.

3.4.3 Data Retransmission
WTS series supports data retransmission to ensure network sever can get all data even if network is down for some times. There are two ways to get the lost data:

• Network server sends downlink commands to enquire the historical data for specifying time range, refer section Historical Data Enquiry;
• When network is down if no response from LinkCheckReq MAC packets for a period of time, the device will record the network disconnected time and re-transmit the lost data after device re-connects the network.

Here are the steps for data retransmission:

1. Enable data storage feature and data retransmission feature.
2. Enable rejoin mode feature and set the number of packets sent. Take below as example, the device will send LinkCheckReq MAC packets to the network server regularly to check if the network is disconnected; if there is no response for 4+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 reporting interval.

Note:

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

5.4 Historical Data Enquiry
WTS series support sending downlink commands to enquire historical data for specified time point or time range. Before that, ensure the device time is correct and data storage feature was enabled to store the data.
Command format:

bytes), Unix timestamp
fd| 6d (Stop query data report)| ff
ff| 6a (Report Interval)| 3 Bytes, Byte 1: 01
Byte 2: interval time, unit: s, range: 30~1200s (60s by default)

Reply format:

01: time point or time range invalid 02: no data in this time or time range
21| ce (Historical Data)| Data time stamp (4 Bytes) + Temperature (2 Bytes) + Humidity (1 Byte) + Pressure (2 Bytes) + Wind Direction (2 Bytes) + Wind Speed (2 Bytes) + Rainfall (4 Bytes)

Note:

1. The device only uploads no more than 300 data records per range enquiry.
2. When enquiring the data in time point, it will upload the data which is closest to the search point within the reporting interval range. For example, if the device’s reporting interval is 10 minutes and users send command to search for 17:00’s data, if the device find there is data stored in 17:00, it will upload these data. If no, it will search for data between 16:50 to 17:10 and upload the data which is closest to 17:00.

Example:

1. Enquire historical data between 2022/10/10 14:45:00 to 2022-10-10 15:35:00.
