TapoController
Local TP-Link Tapo L530 controller: Ambilight, music sync, no cloud
TapoController is a Windows desktop app that controls TP-Link Tapo L530 smart bulbs entirely on your LAN — no cloud, no vendor SDK. It uses its own reverse-engineered implementation of the Tapo local protocol (KLAP) and drives one bulb or several in sync.
One-time requirement
Enable "Third-Party Services" once in the Tapo mobile app. After that, all control is local (no internet needed).
