+Usage: $0 bridge-name [-t type] [-i id] [-s sensor] [-b percent] [-a action] [-v] [-d]
+Options:
+bridge-name    as defined in [HOME]./hue.conf or [HOME]./.hue.conf or /etc/hue.conf
+-t | --type    [ lights | sensors | groups | all | trigger ] (default: lights)
+-i | --id      light-id
+-s | --sensor  sensor-id
+-b | --battery percent of battery level to report on, only relevant with sensors
+-a | --action  [ on | off | state | bright | relax | morning | dimmed | evening | nightlight ] (default: state)
+-v | --verbose JSON output
+-d | --debug   pretty JSON output 
+
+Command examples:
+$0 bridge1
+	Displays all lights of bridge1
+$0 bridge1 -i 8
+	Check for state of light-id 8
+$0 bridge2 -t lights -i 8 -a bright
+	Turn on light-id 8 with the scene bright
+$0 bridge2 -t trigger -i 8 -s 34 -a evening
+	Check for 'dark' state of sensor-id 34, turn on light-id 8 with the scene evening
+
+Config example:
+# huectl,pl config file locations:
+# ~/hue.conf, ~/.hue.conf, /etc/hue.conf, ./.hue.conf, ./hue.conf
