Home Assistant custom integration
Humidity Intelligence acts as a stabiliser for your home environment. It uses data from Home Assistant smart sensors to help guide air purifiers, extractors, humidifiers, and dehumidifiers, so your home can stay fresher, calmer, and more comfortable day to day.
Why it exists
With global temperatures rising and warmer, more humid weather patterns becoming more common across parts of the Northern Hemisphere, indoor humidity is becoming harder to ignore. In many homes, conditions that once shifted slowly with the seasons can now change in a single day: damp air after showers, cooking, or warm weather, then drier air when heating, cooling, or ventilation takes over.
Those swings can affect more than comfort. Humidity that sits too high or too low may contribute to dry skin, irritated eyes, coughing, respiratory sensitivity, stressed houseplants, condensation, mould risk, and, over time, damage to the fabric of a home. Heat and humidity together can also put extra strain on the body, because humid air makes it harder for sweat to evaporate and cool us down.
Humidity Intelligence does not replace good ventilation, heating, cooling, or maintenance. It helps make the indoor picture easier to understand by bringing humidity, temperature, dew point, room behaviour, air quality, and device states together inside Home Assistant, then explaining what is changing, why it matters, and what the next sensible action may be to support a more stable indoor environment.
What it helps with
When the home sends mixed signals, HI follows a fixed priority order: CO emergency, humidity danger, mould danger, mould risk, condensation danger, condensation risk, Zone 1, Zone 2, air quality, then normal operation. You get one clear control decision instead of overlapping automation noise.
Winter and summer homes need different humidity targets. HI reads each room against the active profile, so guidance changes with the season instead of relying on one flat number all year.
The Lovelace dashboards show what HI saw, mapped, skipped, and chose. They are there to make the routine easier to understand, not to invent their own logic.

Support Humidity Intelligence
If HI has helped your home, please consider supporting the project in a practical way: star the repo so others can find it, test a release when you can, open clear issues with diagnostics, or suggest improvements to the docs and UI examples when something could be easier. Sponsorship is completely optional, but it directly supports the maintenance time that keeps HI reviewed, usable, and moving forward.
