📈Polynomial Equations, Without the Headache
Synthetic variables just got a powerful new addition: the poly() function. If your measurements rely on polynomial equations — think tank volume calculations, sensor calibrations, or any non-linear relationship between a raw reading and a real-world value — you no longer have to manually construct and maintain those long, error-prone expressions in the synthetic variable editor. Instead, you simply pass your variable and a set of constants to poly(), and Ubidots automatically builds the full polynomial equation for you behind the scenes. Beyond saving time when setting things up, this also makes device replacements significantly less painful: updating the equation is now a matter of swapping out a few constants rather than rewriting an entire expression. It's a small function with a big impact on anyone working with curve-fitting or calibration-based metrics.
