Has anyone created an automation which pairs humidity with temperature to create a comfortable HVAC environment?
There’s a formula which reads
Humidex – Air temperature in Celsius + 0.5555 (e – 10)
Where:
e = 6.11 x exp [5417.7530 (1/273.16 – 1/Air temperature in Celsius +273.16)]
Humidex reading seems to gather the inputs of temp and humidity to give a comfort level. Wondering if I can use this to formulate some sort of automation using my HVAC.

Maybe this can help you to achieve, what you are looking for. Using the entities created by this integration could get you there…

Does your HVAC system have a De humidification setting already ?Also what kind of thermostat do you have?
Yes there is a Dry mode on it. My sensor is a fairly basic temp and humidity zigbee sensor.
Do I need more sensors for this to work? Apologies if that is a daft question.

a temperature sensor and a humidity sensor is needed for it to work.
I dowloaded that HAC - I suppose now I have to work out how to create an automation which juggles temperature and humidity - the dry function makes it colder - not sure how to handle that.

# Initial Configuration
## In your Home Assistant UI go to "Configuration", then click "Devices & Services"
![Config Dashboard](https://raw.githubusercontent.com/dolezsa/thermal_comfort/master/screenshots/config_dashboard.png)
## Make sure Integrations is selected and click the "+" button in the bottom right corner
![Config Integrations](https://raw.githubusercontent.com/dolezsa/thermal_comfort/master/screenshots/config_integrations.png)
## Search for or scroll down to find "Thermal Comfort" and select it
![Config Integrations Search](https://raw.githubusercontent.com/dolezsa/thermal_comfort/master/screenshots/config_integrations_search.png)
## Name your virtual device and select the temperature and humidity sensor you want to use
*Note: Enable [advanced mode](https://www.home-assistant.io/blog/2019/07/17/release-96/#advanced-mode)
in your user profile if you want additional options.
We filter the sensors to include only those who have the correct device class.
If you want to select other make sure to enable

then you should have more sensors:
heat_index is what you are looking for
