A integration for Home-Assistant that predicts how long you have to open your windows (specially optimized for bathrooms, but should work for any other room too) in order to prevent mold and other nasty things. You can use it for example to get notification how long you should vent if it is necessary.
Install HACS
Use this link:
And install the integration
You can configure and setup this integration via a Config Flow. Thanks a lot to Alexwijn
0 minutesmeans venting doesn't make sense right now because the outside is to humid1-299 minutesmeans you should vent for that amount of time300 minutesmeans it would take 300 minutes or longer to ventunavailablemeans one or more of the temperature and humidity sensors are unavailable
If you want to customize the opimization to adapt to your local situation gather training data and use either this jupyter notebook or this webapp (under "Training" (i am sorry it is currently German only))
To learn about the model and the optimization itself have look at the whole repository dedicated to the development of the model and the webapp
This integration used the Mold Indicator Integration as a minimal template to start from.
