Therm (P039) plugin problem
Posted: Thursday 25 May 2017 8:14
I have enabled the P039 thermocouple device on ESP8266-07 device and have encountered a problem.
For positive temperatures of 0 degrees and above it looks fine. As soon as it goes negative, the reading jumps to values around 4000 degrees.
Looks like some adjustment has not been made for negative values?
I am using the MAX31855 IC
