Smart Switches
Overview
SGT Smart Switches are in-wall touch and rocker switches that replace your existing wall switch and bring app control, scenes, dimming and routines to the lights you already own — no need to change every bulb in the house.
Available as single, 2-gang and 3-gang touch faces, classic rocker, dimmer, and 3-way / 4-way configurations. They fit the same back-box as a normal switch, support installations with or without a neutral wire (essential in older homes), and detect their load automatically so LED, incandescent and halogen all dim cleanly without flicker.
- No-neutral support — works in older homes without rewiring
- Auto load detection — LED, halogen, incandescent, all dim flicker-free
- Scene buttons — long-press the face for Read / Movie / Dine / Sleep
- 3-way / 4-way — pair multiple switches for the same light, in sync 18 ms
How It Works
The diagram above traces a tap on the wall, through the on-board MCU, the triac dimmer and back out to the load — with the cloud and the family’s phones kept in sync the whole time. Hover any module to see its live telemetry.
- The switch — capacitive touch (or mechanical rocker) face with status LED bar, a sleep-friendly dim glow, and dedicated scene buttons.
- Load & wiring — on-board triac handles 1–300 W LED or 1–500 W incandescent, with thermal protection on the triac and live/neutral monitoring.
- Cloud routines — scenes and time-of-day routines live in the cloud and sync to every switch instantly.
- App & voice — iOS / Android app, Alexa, Google, Apple Home; family profiles see only the rooms they have access to.
The cyan stream along the bottom of the diagram is the live command channel — scene, dim and routine pushes flowing back to every switch.
