Don’t understand how the TREND sensor works or how to calculate it.
Today have a temperature sensor that sends a value every 60sec.
If I want to know if the temperature is rising or falling, how should I calculate?
Say I want in a time span of 15 min want to know if the temperature has risen or fallen by at least 0.5 degrees?
It would be great if someone could help me set up a helper so that I can get an indication of whether the temperature is rising or falling.
