This post explains how to control a TP-Link HS100 smart plug remotely via the internet using command-line tools, bypassing local WiFi limitations and allowing integration with automation apps like Tasker and IFTTT. It describes the communication process between the Kasa app, TP-Link web service, and the smart plug, highlighting the authentication token, device ID, and relay state used for commands. The author also details how to replicate the app’s HTTP requests using curl to turn the plug on or off from any internet-connected device. Although some earlier methods to extract needed data from app backups are now outdated, updated guides for gaining access tokens and device info from the TP-Link cloud API are provided.
