Register null data into bucket

[ega]

I would try something like this:

thing["temp"] >> [](pson & out) {
                   sensors.requestTemperatures();
                   int tempRead = sensors.getTempCByIndex(0);
                   if (tempRead != -127)
                   {
                     out["TEMPERATURA"] = tempRead;
                   }
          };

In this way the “thing” will send a value only if its different to -127.

Hope this helps
