$ plugctl
  -credentials="admin:admin": credentials specify as <login>:<pass>
  -csvfile="output.csv": file to write csv output to (only used with -daemon)
  -daemon=false: run as a (foreground) daemon with polling webserver
  -debug=false: show debug information
  -do="info": enable/disable/info/disableAP/uptime/reboot
  -info="W": W/E/V/I
                W = centiWatt
                E = milliWatts/h
                V = milliVolts
                I = milliAmps
  -ip="192.168.8.74": ipv4 address of smartplug device
  -port=8080: webserver port (only used with -daemon)
  -raw="": raw command to execute on device (via http)
  -rawt="": raw command to execute on device (via telnet)

-do enable / disable: to enable/disable the power output of the plug
-do disableAP: to disable AP mode on the smartplug (for security reasons)
-do uptime: show uptime of the device
-do reboot: reboots the device (does not impacts the power output)
-do info: get information about the power status (needs -info option)

-raw "command": executes a command on the plug (it's running busybox/linux)(via http)

sending commands via http is limited, only one command is possible, can't chain commands) -rawt "command": executes a command on the plug (it's running busybox/linux)
here you can chain commands. eg command1 && command2

-daemon: starts a webserver and polls the device every second for information

• port: specify listen port for the webserver (default 8080) (only needed with -daemon)
• csvfile: specify cvsfile to write to (default "output.csv") (only needed with -daemon)

When -daemon option is used, a webserver will listen by default on port 8080

• /history - webpage/javascript which parses the csvfile history + current data into a chart

• /stream - webpage/javascript which shows a realtime chart

Enable plug on ip 192.168.1.50 with login admin and password test

$ plugctl -ip 192.168.1.50 -credentials "admin:test" -do enable
enabling plug.

Get centiWatt usage information about plug on ip 192.168.1.50 with default password

$ plugctl -ip 192.168.1.50 -info W -do info
1058 W

Disable the AP mode on the smartplug (for security reasons). This is not saved on reboot!

$ plugctl -do disableAP
disabling AP.

View the CPU info of the device by using the raw command

$ plugctl -raw="cat /proc/cpuinfo"
executing command: cat   /proc/cpuinfo

system type             : Ralink SoC
processor               : 0
cpu model               : MIPS 24K V4.12
BogoMIPS                : 239.61

Get all the usage information Watt/Ampere/Energy/Volt in one go using the rawt command

$ plugctl -rawt "GetInfo W && GetInfo I && GetInfo E && GetInfo V"

Start daemon/webserver on port 8888 with debug and device on ip 192.168.1.50 and save CSVfile to plug.csv

$ plugctl -daemon -debug -port 8888 -ip 192.168.1.50 -csvfile plug.csv
starting foreground daemon ;-)
