The brain: Banana Pro with Home Assistant
My Pi 2's micro sd card broke very quickly, so I've been working on a more stable replacement in the form of a Banana Pro board. I installed Bananian on the sd card and then moved the installation to a read hard disk connected to the SATA port. Hopefully this will survive longer.
Home Assistant
I followed this Installation instructions. This worked fine once I installed some dependencies for the discovery component (I don't know which one did the trick):
apt-get install build-essential checkinstall python3-dev
To have it autostart as a service, I use this /etc/init.d/hass-daemon script:
#!/bin/sh
### BEGIN INIT INFO
# Provides: hass
# Required-Start: $local_fs $network $named $time $syslog
# Required-Stop: $local_fs $network $named $time $syslog
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Description: Home\ Assistant
### END INIT INFO
PRE_EXEC="python3 -m venv /srv/homeassistant/homeassistant_venv && . /srv/homeassistant/homeassistant_venv/bin/activate;"
RUN_AS="homeassistant"
PID_FILE="/var/run/hass.pid"
CONFIG_DIR="/home/homeassistant/.homeassistant"
FLAGS="-v --config $CONFIG_DIR --pid-file $PID_FILE --daemon"
REDIRECT="> $CONFIG_DIR/home-assistant.log 2>&1"
start() {
if [ -f $PID_FILE ] && kill -0 $(cat $PID_FILE) 2> /dev/null; then
echo 'Service already running' >&2
return 1
fi
echo 'Starting service…' >&2
local CMD="$PRE_EXEC hass $FLAGS $REDIRECT;"
su -c "$CMD" $RUN_AS
echo 'Service started' >&2
}
stop() {
if [ ! -f "$PID_FILE" ] || ! kill -0 $(cat "$PID_FILE") 2> /dev/null; then
echo 'Service not running' >&2
return 1
fi
echo 'Stopping service…' >&2
kill $(cat "$PID_FILE")
while ps -p $(cat "$PID_FILE") > /dev/null 2>&1; do sleep 1;done;
echo 'Service stopped' >&2
}
install() {
echo "Installing Home Assistant Daemon (hass-daemon)"
echo "999999" > $PID_FILE
chown $RUN_AS $PID_FILE
mkdir -p $CONFIG_DIR
chown $RUN_AS $CONFIG_DIR
}
uninstall() {
echo -n "Are you really sure you want to uninstall this service? That cannot be undone. [yes|No] "
local SURE
read SURE
if [ "$SURE" = "yes" ]; then
stop
rm -fv "$PID_FILE"
echo "Notice: The config directory has not been removed"
echo $CONFIG_DIR
update-rc.d -f hass-daemon remove
rm -fv "$0"
echo "Home Assistant Daemon has been removed. Home Assistant is still installed."
fi
}
case "$1" in
start)
start
;;
stop)
stop
;;
install)
install
;;
uninstall)
uninstall
;;
restart)
stop
start
;;
*)
echo "Usage: $0 {start|stop|restart|install|uninstall}"
esac
Now we need to enable this:
update-rc.d hass-daemon defaults service hass-daemon install
From now on the service will autostart when machine boots, and can be started and stoppen with:
service hass-daemon start service hass-daemon stop
Sensors
NRF nodes
Most probably I will use the hardware designed by User:Zarya as mentioned in NrfSensorNode. They will run the library from https://www.mysensors.org/.
Lights
Philips Hue
Got some Philips Hue stuff for cheap. It's the Hue Bridge v1, and 3 LED lights that work just fine, although 2 of them are missing the glass bit. They do whites and colors \o/. They are supposed to integrate with Home Assistant very easily: https://home-assistant.io/components/light.hue/ <gallery> Image:Hue.jpg </gallery?
