RPI5 enable uart on GPIO14&GPIO15 on /dev/ttyAMA0

Feature Requests
1

On Raspberry Pi 5 GPIO14&GPIO15 are mapped by default to serial terminal (previous rpi4,3… didn’t have that config). In order to use uart on this dedicated GPIO in Raspbian config, one should disable remote terminal on this serial port and enable uart for this pins. This is necessary for ebus adapter for heating systems. More details at Raspberry Pi Connection - eBUS Adapter Shield v5.

This configuration cannot be done in HAOS, so we cannot use HAOS on raspberry 5 with adapter connected to PIN header.

Can you provide a way to configure HAOS to enable uart on GPIO14&15.

Thank you

ps. the issue is discussed here too, but no feature request found on the topic: Enable serial port ttyAMA0 - #4 by francisp

GPIO is not supported in HAOS anymore.
There is a fork of the old integration, but the library it is based on does not support RPi5 and the maintainer seems to have given up on making the change, since it require a complete rewrite.
There is another integration based on another library that should work.

Thank you. Could you please provide the link to the fork of old integration, too, and the source of info that HAOS does not support GPIO anymore, so we have all in one place, and future users will not search TheInternet for all the info.

And, if interested, please vote for the request, maybe the maintainer will consider supporting GPIO in the future.

The old integration and the description of it mention when it was removed from HA core.
You can look up the release notes from then.
