The LiteTouch Guide: A Six-Part Reference Series

LiteTouch was a panelized, hardwired lighting control system common in high-end Houston-area homes built from the late 1980s through the early 2010s. Savant discontinued the platform in 2015 — no new hardware, no software updates, no official parts supply. This series is a reference index for owners trying to understand the system, diagnose a fault, or plan a replacement, organized as a reading path rather than a single long article.
