Bash script to turn off all Philips Hue Lights

turn-off-lights.sh

# This script requires jq (https://stedolan.github.io/jq/) for JSON parsing. Would be great to get rid of that dependency.
# Besides that you need to create an API user for you Philips Hue Bridge as described here:
# https://developers.meethue.com/develop/get-started-2/#so-lets-get-started

#!/bin/bash

LIGHTS=$(curl -s http://$HUE_API_ADDRESS/api/$HUE_API_USER/lights | jq 'keys[]')

for i in $LIGHTS
