A replacement for the motherboard of the Intex Spa SSP-20 using an ESP32. It adds remote control trough MQTT protocol and a REST server. It also increase the reliability of the Spa (no more E9X errors)

Defaults coefficients for the Steinhart-Hart equation and not accurate for temperature reading. #4

The value provided by the read temperature function using the Steinhart-Hart equation with default coefficients are not accurate.

I need to make a calibration to determine correct coefficients for Intex probes.
