Lighting and Blinds in Home Assistant
Module 20 turns Home Assistant toward the two hardware categories every smart home eventually touches: light and blinds. It opens with the module's overriding three-layer rule, manual control must work day one, scenes come next, automations only at the end, then walks through lighting hardware from smart bulbs to relays, dimmers, and LED strips, the single most consequential buying decision (a smart bulb or an in-wall relay), and the electrical diagnosis a switch box needs before any module purchase. Blinds get an equally careful treatment: identifying what you're really controlling before choosing a drive, and a mandatory safety lesson on limit switches, patio door lockouts, and wind protection that never gets skipped for a schedule. From there the module builds up entities, manual control with a real Plan B, six lighting scenes, motion-activated lighting that survives the classic bathtub problem, and sun-and-temperature-driven automation for both light and blinds that knows when to defer to a person. It closes with a Home and Technical dashboard split, a four-room mini project, and a readiness checklist that treats a backup and a working Plan B as two different things.
A light switch and a blind cord have worked without a network connection for decades, and a smart home has to earn the right to sit between a household member and that reliability, not replace it. Every lesson in this module builds toward the same layered chain: manual control first, a tested Plan B second, a deliberately triggered scene third, and only then an automation that a household member can still see, understand, and override. That's why the module spends four lessons on hardware and wiring diagnosis before a single automation gets written, treats a blind's percentage position as an estimate rather than a fact, insists a door contact sensor can never confirm a patio is empty, and requires a manual STOP to defer comfort automation for real time, not seconds. Built this way, lighting and blinds in your home stop being a system you have to babysit and become a set of points that fail safely, explain themselves, and still work when the network doesn't.

By the end of Module 20, you'll have a room-by-room light and blind map with a tested Plan B for every point, a settled smart-bulb-versus-relay decision backed by real electrical diagnosis, six working lighting scenes, motion-activated lighting that respects a manual override, sun-and-temperature automation for both light and blinds that defers to STOP and a patio lockout, and a Home and Technical dashboard with a documented, dated readiness checklist. Module 21 takes this same map-first, safety-first approach outdoors, covering garden and driveway lighting, gates, irrigation, and outdoor cameras in Home Assistant.
