I have any problem with set up ENOCEAN PI modul with my HASSIO.
home-assistant.log:
2021-07-27 11:25:13 ERROR (MainThread) [homeassistant.components.serial.sensor] Error while reading serial device /dev/ttyACM0: device reports readiness to read but returned no data (device disconnected or multiple access on port?)
Maybe conflict with CONBEE on USB?
