Please refer to the original blueprint for a full description of the functionalities implemented.
Thank you very much Sbyx for the excellent contribution, which I have successfully implemented in my HA installation and which prompted me to make this little customization, which I hope will be useful to others as well.
Blueprints are a quick way to implement HA automations that have been written (and hopefully tested and debugged) by other users and are believed to be useful to the Home Assistant user community.
Using blueprints, you just import the code of an automation ready to use.
This project, in particular, periodically checks the humidity status reported by the miflora sensors and, if it finds any below the defined threshold, it sends a notification through any notifier defined in HA.
In my case, I chose to set the check every day at 10:00 and receive a message on Telegram every time that some sensor reports a humidity below 20%. All parameters are fully customizable.

I was looking to do just the same, but stumbled upon your code. Which is great. However, how is this working for you? My sensor for moisture doesn’t have a device class
I do have an Aqara temp/humidty sensor, which would show up in your code, but never get selected because there’s no minimum for such a sensor
So what I did is tweak the filtering. The convention here is that your icon remains mdi:water-percent.
I don’t see any other way at the moment.
Also replaced a little missed adjustment where in the Actions part you left “battery” instead of “humidity”
