How to calibrate sensor data before its display

[sazaki]

I have an ESP32 that sends sensor data to a "Custom Sensor" in domoticz via http. The sensor data is raw and needs to be calibrated (re-calculated using a function y=a*x+b) before it is shown in domotic's "Custom Sensor. I understand that I can do the data calibration in the ESP32 side before I send the data to domoticz. However, for some reasons, I would like to have the calibration done in Domoticz. I would like to use blocky to do the calibration work when data is received than shows it in the "Customer sensor". I wonder if this is feasible?? Please help. Thank you very much.

No that's not feasible. The Blockly implementation in domoticz does not have any math functions.
