Good day. Thank you for your question.
The 1-wire power will be exhibited once the device is given a power supply. So if you would like to receive the data of the 1-wire temperature sensor, kindly enable the following on your configurator.
Also, you may refer to the connection at https://wiki.teltonika-gps.com/view/1-Wire_Temperature_Sensors
Please try this out and let me know if it helps.
