Home Assistant integration uses dew point data to help prevent mold
Thermal Comfort adds extra climate measurements to Home Assistant using temperature and humidity readings from smart sensors.
The integration calculates values such as dew point and the actual amount of moisture in the air.
Dew point data can guide heating automation intended to protect cold wall surfaces from mold.
By comparing indoor and outdoor moisture, Home Assistant can suggest when to ventilate by opening windows.
The integration also provides measurements such as a heat index and options for climate dashboards.
Some features require manual installation from GitHub, followed by sensor setup and automation configuration.
The guide explains how to set up these functions to help manage indoor climate and heating.
Home Assistant’s Thermal Comfort integration calculates dew point and other climate measures from temperature and humidity readings.
Dew point data can support automated heating intended to protect wall surfaces from mold.
The integration can also compare indoor and outdoor absolute humidity to suggest when to ventilate.
It provides additional measures, including the heat index, and options for refining dashboards.
The Heise article describes installing and setting up the integration and creating automations, including a manual installation route through GitHub.
