Thermal Comfort provides the following calculated sensors for Home Assistant.

Sensors:

Absolute Humidity

Absolute humidity is a measure of the actual amount of water vapor (moisture) in the air.

Heat Index

The heat index combines air temperature and relative humidity to posit a human-perceived equivalent temperature.

Humidex + Perception

The humidex (humidity index) describes how hot the weather feels to an average person as a result of the combined effect of heat and humidity. It is calculated from the dew point.

Dew Point

The dew point is the temperature to which air must be cooled to become saturated with water vapor and dew forms on surfaces.

Thermal Perception

Human perception of the dew point.

Frost Point

Frost point, temperature, below 0° C (32° F), at which moisture in the air will condense as a layer of frost on any exposed surface.

Frost Risk

Risk of Frost based on current temperature, frost point and absolute humidity.

Summer Simmer Index

Provides a proven indicator of heat stress concerns and discomfort using meaningful equivalent temperature values for general public acceptance and awareness.

Summer Simmer Zone

Human perception of the summer simmer index.

Moist Air Enthalpy

The enthalpy of moist air is the sum of the enthalpy of the dry air and the enthalpy of the water vapour. Enthalpy is the total energy of a thermodynamic system.

Summer Scharlau Index/Perception

The summer Scharlau index describes a bioclimatic thermal comfort when temperature values are higher than 0°C. Valid for temperatures 17° to 39°C (63° to 102°F) and humidity >= 30%.

Winter Scharlau Index/Perception

Reflects the level of human discomfort caused by cooling. Valid for: temperatures -5 to +6°C (23 to 43°F) and humidity >= 40%.

Usage

To use Thermal Comfort check the documentation for your preferred way to setup sensors.

UI/Frontend (Config Flow) 1.5.2 / master

YAML 1.5.2 / master

Legacy YAML 1.5.2

Installation

Requirements

Home Assistant >= 2021.12.0

Using HACS (recommended)

This integration can be installed using HACS. To do it search for Thermal Comfort in the integrations section.

Manual

To install this integration manually you can either

• Use git:

git clone https://github.com/dolezsa/thermal_comfort.git
cd thermal_comfort
# if you want a specific version checkout its tag
# e.g. git checkout 1.0.0

# replace $hacs_config_folder with your home assistant config folder path
cp -r custom_components $hacs_config_folder

• Download the source release and extract the custom_components folder into your home assistant config folder.

Finally you need to restart home assistant before you can use it.

Custom Icons

Install Thermal Comforts icon pack.

Enable the custom icons options for your sensor in the frontend or in yaml.
