How to get TOKEN:
==================
1) Get an UUID v4 from https://www.uuidgenerator.net/version4 or run `uuid` in the Mac terminal. Replace it in the command below.

2) Replace your username (email address) and password from your Kasa account below.

2) Run this with the replaced UUID and your email address (as user name) and your password in the console:

curl -XPOST -H "Content-type: application/json" -d '{
 "method": "login",
 "params": {
 "appType": "Kasa_Android",
 "cloudUserName": "[email protected]",
 "cloudPassword": "PASS",
 "terminalUUID": "REPLACE THIS WITH A v4 UUID!!!"
 }}' 'https://wap.tplinkcloud.com'
 

3) write it down here, look for the "token":
 
Your TOKEN ("token"): 
> ...

How to get Device ID(s):
=======================
 
1) Use your token from above and replace the command below with it.

2) Run the command in the console with your token.

3) You will get a list of your devices. Check for the "deviceId". 
   If you need to format the response to better read it, paste it at http://jsonviewer.stack.hu and click the "Viewer" tab.
 
 curl -s --request POST "https://wap.tplinkcloud.com?token=TOKEN HTTP/1.1" \
  --data '{"method":"getDeviceList"}' \
  --header "Content-Type: application/json"
 
4) Search your "deviceId" and write it down: 
 Your Device ID ("deviceId"): 
 > ...
 
FINALLY:
=========

1) Replace those two variables in the two commands at the top.
   You will need to replace twice the TOKEN and twice the DEVICEID.
 
2) Then save. You can now run the script in the console with 
 ./tplink.sh 1   # to turn on
 or
 ./tplink.sh 0  # to turn off
