Thanks for keeping this plugin alive!

As of 2023-12-04, Following the directions for 13.2 here:

Got a few errors on service homeassistant start :

5. Finally & hopefully without errors: service homeassistant start

Home Assistant now is generating a warning about Python 3.11, and the move to Python 3.12 only.

Python 3.12 is problematic on FreeBSD because of the changes in setup tools. However with the way Python is used for Home Assistant (with pip venv packages only), this does not necessarily pose a problem.

Python 3.11 can be uninstalled from pkg and Python 3.12 installed as follows:

RELEASE=3.12.2

cd /root
wget -qO- https://www.python.org/ftp/python/${RELEASE}/Python-${RELEASE}.tar.xz | tar -xJ
cd /root/Python-${RELEASE}/
./configure --disable-test-modules --enable-optimizations
make -j $(nproc)
make altinstall
rm -f -R /root/Python-${RELEASE}

This makes python3.12 available in /usr/local/bin/python3.12. Run this only in a iocage or jail on FreeBSD!
All the above steps still apply and the rc.d script works fine.

Edit: Hacky script for the whole thing:
