Thank you for your support.

https://parse.ubidots.com/{UBIFUNCTION-URL}/?token={UBIDOTS-TOKEN}&device={SIGFOX-DEVICE-ID}&variable={VARIABLE_LABEL}

should I replace {VARIABLE_LABEL} with what?

  1. Erase and replace the default code located in the UbiFunction editor
    After replacing the code with the code in the link, should I change/replace something from the code?

Hi @wael,

You should replace{VARIABLE_LABEL} with the label of your variable of interest, the label refers to a unique identifier within the Ubidots time-series backend. To find the label go to Devices → Sigfox device → Variable (temperature, frequency, pressure, etc)

Regarding the second question, no, you don’t need to replace or enter any parameter in the code.

All the best,
