This block of code extracts the value of the '''‘value’''' parameter from the ‘status’ output using '''‘grep’'''and '''‘sed’''' and stores it in the ‘value’ variable.

This block of code extracts the value of the '''‘value’''' parameter from the ‘status’ output using '''‘grep’'''and '''‘sed’''' and stores it in the ‘value’ variable.

After that, it checks if the value stored in the '''‘value’''' variable is equal to 0. If it is, the '''‘ubus’''' command is used to call the '''‘ioman.gpio.onewire’''' service and execute the ‘update’ command, which updates the ‘value’ parameter to 1.

This block reads the temperature data from the device file '''‘$sensor_dir/w1_slave’''' and extracts the raw temperature value using '''‘grep’''' and '''‘awk’'''. The temperature value is encoded as an integer.

This block reads the temperature data from the device file '''‘$sensor_dir/w1_slave’''' and extracts the raw temperature value using '''‘grep’''' and '''‘awk’'''. The temperature value is encoded as an integer.

Which then converts the raw temperature value to degrees Celsius by dividing it by 1000 and then formatting it with two decimal places using '''‘printf’'''. The resulting temperature value is stored in the '''‘temp’''' variable.

This line uses the '''‘curl’''' command to send an HTTP POST request to the server specified by '''‘$SERVER_URL’'''. The '''‘-X POST’''' option specifies that the request should be a POST request, and the '''‘-H “Content-Type: application/json”’''' option specifies that the payload data is in JSON format. The '''‘-d “$PAYLOAD”’''' option specifies the payload data to be sent with the request.
