Installation on FreeNAS 11.2


FreeNAS is a free and open-source network-attached storage (NAS) software based on FreeBSD and the OpenZFS file system. It is licensed under the terms of the BSD License and runs on commodity x86-64 hardware.

This has been tested on FreeNAS 11.2 and should also work on FreeBSD 11.x as well. These instructions assume you already have a running and accessible jail. For more information on creating a jail read the official FreeNAS User Guide regarding Jails. Once you have the jail available, follow the steps below. Directories used follow standard BSD conventions but can be adjusted as you wish.

Create the user and group that Home Assistant will run as. The user/group ID of 8123 can be replaced if this is already in use in your environment.

pw groupadd -n homeassistant -g 8123
echo 'homeassistant:8123:8123::::::/bin/csh:' | adduser -f -

Install the necessary Python packages:

pkg update
pkg upgrade
pkg install -y python37 py37-sqlite3 ca_root_nss
python3.7 -m ensurepip

Create the configuration directory:

mkdir -p /usr/local/homeassistant
chown -R homeassistant:homeassistant /usr/local/homeassistant

Create the installation directory:

mkdir -p /usr/local/share/homeassistant
chown -R homeassistant:homeassistant /usr/local/share/homeassistant

Install Home Assistant itself:

su homeassistant
cd /usr/local/share/homeassistant
virtualenv -p python3.7 .
source ./bin/activate.csh
pip3 install homeassistant
deactivate
exit

Create an rc.d script for the system-level service that enables Home Assistant to start when the jail starts. Create a file at /usr/local/etc/rc.d/homeassistant with the following contents:

#!/bin/sh

# PROVIDE: homeassistant
# REQUIRE: LOGIN
# KEYWORD: shutdown
#
# homeassistant_enable:    Set to YES to enable the homeassistant service.
#            Default: NO
# homeassistant_user:    The user account used to run the homeassistant daemon.
#            This is optional, however do not specifically set this to an
#            empty string as this will cause the daemon to run as root.
#            Default: homeassistant
# homeassistant_group:    The group account used to run the homeassistant daemon.
#            This is optional, however do not specifically set this to an
#            empty string as this will cause the daemon to run with group wheel.
#            Default: homeassistant
# homeassistant_config_dir:    Directory where config files are located.
#            Default: /usr/local/homeassistant
# homeassistant_install_dir:    Directory where Home Assistant is installed.
#            Default: /usr/local/share/homeassistant
#
# sysrc homeassistant_enable=yes
# service homeassistant start

Make the rc.d script executable:

# chmod +x /usr/local/etc/rc.d/homeassistant

Configure the service to start on boot and start the Home Assistant service:

sysrc homeassistant_enable="YES"
service homeassistant start

You can also restart the jail to ensure that Home Assistant starts on boot.

USB Z-wave sticks may give dmesg warnings similar to “data interface 1, has no CM over data, has no break”. This doesn’t impact the function of the Z-Wave stick in Home Assistant. Just make sure the proper /dev/cu* is used in the Home Assistant configuration.yaml file.
