I use this in a Home Assistant Template helper so it's updated automatically when any of the source sensors update. This is based on the simplified formula documented by the BoM here: http://www.bom.gov.au/info/thermal_stress
Substitute your sensor names
- YOUR_TEMP_SENSOR - degrees C
- YOUR_HUMDITY_SENSOR - percentage
- YOUR_WIND_SPEED_SENSOR - km/h
