#!/bin/bash

# To install, run the following command:
#
# wget http://pastebin.com/raw/CwXh0vfN -O- | tr -d '\r' | sudo tee /usr/local/bin/hassctl > /dev/null && sudo chown pi:pi /usr/local/bin/hassctl && chmod +x /usr/local/bin/hassctl
#
# Now you can control hass using:
#   hassctl start
#   hassctl stop
#   hassctl restart
#   hassctl kill
#   hassctl log -f
#   hassctl error
#   hassctl config
#   hassctl update
