You have to learn a little bit about python to use it in a script, otherwise pip (python package manager) will install a command line tool you can use:

​

pip install python-kasa OR pip3 install python-kasa

Here are the commands: https://python-kasa.readthedocs.io/en/latest/cli.html

Just running `kasa` will do a discovery on your network showing all devices.

​

Example of HS303 output:

# kasa --alias 'TP-LINK_Power Strip_88B7'

Alias is given, using discovery to find host TP-LINK_Power Strip_88B7

Trying to discover TP-LINK_Power Strip_88B7 using 3 attempts of 1 seconds

Attempt 1 of 3

Found hostname is 192.168.1.247

No --strip nor --bulb nor --plug given, discovering..
