      We already have layers for Heat and for Dew Point.

      The "Heat Index" is much more intuitive to most users. Please provide this new layer calculated as:

      First, get
      RH (relative humidity, %):
      es = 6.112 * exp(17.67 * T / (T + 243.5))
      e = 6.112 * exp(17.67 * D / (D + 243.5))
      RH = 100 * e / es
      T = air temperature (°C)
      D = dew point (°C)

      Then heat index (HI, °C):
      HI = -8.784695
      1.61139411 * T
      2.338549 * RH
      0.14611605 * T * RH
      0.012308094 * T * T
      0.016424828 * RH * RH
      0.002211732 * T * T * RH
      0.00072546 * T * RH * RH
      0.000003582 * T * T * RH * RH”

      These RH and HI formulas are standard Magnus-type humidity and heat-index polynomials in °C.

      I'm guessing US users' preference settings for Fahrenheit will handle that conversion?

      Onward and upward,

        @wlpendley Hello, right now there is no plan for this, however, we are planning to offer at least feel like temperature in the upcoming version.
