C4 → HA Migration Field Guide

A practitioner’s field guide to migrating a whole-home Control4 AV system to Home Assistant — without downtime and without a rip-out weekend.

Two ways in

Deciding whether to leave Control4? Start with the decision layer → decision/. It walks the honest tradeoffs before you spend a dollar or pull a single zone.
Already migrating? Go straight to the framework, the build guide, and the lessons → framework/, building/, and gotchas/. The framework gives you the sequence; the build guide shows how to do it well in Home Assistant; the gotchas keep you from re-learning things the hard way.

decision/ — Should you leave Control4 at all? Tradeoffs, what you’re signing up for, and a readiness self-check.
framework/ — The repeatable 5-stage migration model plus the cross-cutting principles that hold across every house.
building/ — Building it well in Home Assistant: integrations, Music Assistant, scripting, automations, and platform pitfalls — with small illustrative snippets.
gotchas/ — A growing catalog of hard-won, generalized lessons: the failures, the rules they taught me, and how to apply them.
journey/ — The actual arc of one migration, compressed — proof the framework came from doing, not theorizing.
