Altering Incoming data into bit bucket


I am sending data viz sigfox to my thinger account. I need to scale the values so they represent their true figure.
e.g. I send 33 for a voltage but the actual voltage is 33/10-0.1 = 3.2v. I would like to display this scaled value into the dashboard , now this is just an example I have more convoluted values I need to scale
can I do this with thinger somehow if not do I need to do it via a thirdparty then forward to thinger bit bucket?




Right now is not possible to run any scripts at server instance (I doubt this will change), so yes you need to modify by another device before send values to data bucket.
