This blueprint is a fork from the terrific job of Sbyx (https://community.home-assistant.io/t/low-battery-level-detection-notification-for-all-battery-sensors/258664); I’ve only changed some minor details in order to detect and report the humidity level from my miflora sensors.

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.
