MQTT Io On OrangePi 5

[niraviry]

• [V ] I have read the README.md file and visited the Documentation to see if the information there helps.

Describe the bug
I am running HA (supervised) on my OrangePi 5 Plus under Debian 12 (Bookworm) with latest updates of both OS and HA.
I setup the config.yml file as follows:

Errors appear below in the proper section.

Expected behavior
No errors in the log file (set to debug).

Error messages and traceback

Hi @niraviry,

it looks like, that orangepi module can't set the gpio:

in setup sysfs.export(pin) File "/usr/lib/python3.11/site-packages/OPi/sysfs.py", line 37, in export with open(path, "w") as fp:
OSError: [Errno 30] Read-only file system: '/sys/class/gpio/export'

Any clue, while the file system can't be written?
