# To script is for running Home Assistant as a service and automatically starting it on boot.
# Assuming you have cloned the HA repo into /home/pi/Apps/home-assistant adjust this path if necessary
# This also assumes you installed HA on your raspberry pi using the instructions here:
# https://home-assistant.io/getting-started/
#
# To install to the following:
# sudo cp /home/pi/Apps/home-assistant/scripts/homeassistant-pi.sh /etc/init.d/homeassistant.sh
# sudo chmod +x /etc/init.d/homeassistant.sh
# sudo chown root:root /etc/init.d/homeassistant.sh
#
# If you want HA to start on boot also run the following:
# sudo update-rc.d homeassistant.sh defaults
# sudo update-rc.d homeassistant.sh enable
#
# You should now be able to start HA by running
# sudo /etc/init.d/homeassistant.sh start
