Advanced Settings

Calibration Settings

ToolBox supports temperature calibration. Type the calibration value and save, the device will add the calibration to raw value, then display and report the final value.

Threshold Settings

TS201 can set temperature threshold alarms, temperature change alarms and so on. Enable the threshold settings and enter the threshold. TS201 sensor will upload the current data instantly when the alarm is triggered. Note that when you change the temperature unit, please re-configure the threshold.

value, the device will report an alarm packet.
Temperature change greater than| When this function is enabled, the device will report an alarm packet when the absolute value of the difference between the two collected values exceeds the set threshold.
Collecting Interval| Set the interval of collecting data and reporting alarm, the default interval is 1min.
Alarm Reporting Times| Set the times of alarm report, the default is 1 time.
Alarm Dismiss Report| After it is enabled, when the collected value changes from exceeding the threshold range to not exceeding the threshold range, an alarm dismiss packet will be reported.

Data Storage

TS201 sensor supports storing more than 2800 data records locally and exporting data via ToolBox App. The device will record the data according to the reporting interval even not joining to network.

Here are the steps for storage:

1. Ensure the device time is correct, click Sync to sync the time.
   

2. Enable Data Storage feature.
   

3. Click Export Historical Data, then select the data period and click Confirm to export data. The maximum export data period on ToolBox App is 14 days.
   

Data Retransmission

TS201 sensor 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 Historical Data Enquiry.
• When the 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 the device re-connects the network.

Here are the steps for retransmission:

1. Ensure the device time is correct, please click Sync to sync the time.
   

2. Enable Data Storage and Data Retransmission feature.
   

3. Go to Device > Setting > LoRaWAN Settings to enable rejoin mode and set the number of packets sent. For example, the device will send LinkCheckReq MAC packets to the networkserver regularly to check any network disconnection; if there is no response for 32+1 times, thejoin status will change to de-activated and the device will record a data lost time point (thetimeit reconnected to the network).
   

4. After the network connection is restored, the device will send the lost data from the point in time when the data was lost according to the data retransmission interval (600s by default).

Note:

1. If the device is rebooted or re-powered when data retransmission is not completed, the interrupted retransmission data will be retransmitted first after the network is reconnected to the network, and then the newly triggered retransmission data will be transmitted.
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.

Note:

1. The device only uploads no more than 300 data records per range jnquiry.
2. When enquiring about the data in time point, it will upload the data that is the closest to the search point within the reporting interval range. For example, if the device’s reporting interval is 10 minutes and users send a command to search for 17:00’s data, if the device finds there is data stored in 17:00, it will upload these data. If not, it will search for data between 16:50 to 17:10 and upload the data which is the closest to 17:00.

Example:

1. Enquire historical data between 2024/5/15 10:20:22 to 2024-5-20 10:20:22.
