This line uses '''‘ubus’''' command to call the '''‘ioman.gpio.onewire’''' service and execute the '''‘status’''' command. The output of this command is saved to the ''status'' 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.

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.

These lines define the URL of the server to which the temperature data will be sent and the payload data that will be sent with each request. The payload includes the '''‘sensor_id’''' and '''‘temp’''' variables, formatted as a JSON object.

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.
