Improve Precision on Temperature Sensors

U1 Toolchanger
1

On the Fluidd and Mainsail interface, the U1 reports temperatures to one degree of precision. Is there some way I can increase the precision to say 0.1°C, so the graphs look a bit smoother?

I know the accuracy might not be great, this is mostly an aesthetic choice.

I doubt it. The thermistor is measured using a basic DAC pin on the microcontroller (probably 8 or 10-bit resolution), which is (probably) no better than one or two increments per degree, and might well go through a linearisation calculation as well.
