Fully local control of a Samsung TV from Home Assistant
The maker patched the QuietTizen launcher with a custom API and built QuietThings, a Home Assistant integration tested on a Samsung QN90B; its patch kit is designed for Claude Code or Codex to tailor to each TV and firmware.

The full story
QuietThings gives Home Assistant fully local control of Samsung TVs running QuietTizen, a replacement launcher. It turns the TV on and off, sets volume and mute, switches HDMI inputs and reports their state, over the local network with no cloud, account or extra hardware such as an ESP32 CEC controller.
The maker patched QuietTizen with a small local API and built the integration, testing it on a Samsung QN90B. The patch is delivered as a kit for an AI coding agent: you give it to Codex or Claude Code with your QuietTizen launcher source, and it tailors the patch to your TV and firmware, tests it on the PC first, generates the API token and supports rollback. The maker says differences between models and firmware make a single release impractical.
It needs a Samsung TV in Developer Mode with QuietTizen already working. QuietTizen itself was built for the U8000F, so other models may not work.
