Intelligence in the Wall

Premium smart home modules that bring native Matter control to luxury wall switches. Install behind your existing switch plate. Connect to every major platform. No cloud dependency. No visible compromise.

Precision Control

Hardware-level TRIAC dimming with zero-crossing detection. Smooth, flicker-free dimming from 0-100% — the kind of control that luxury lighting demands.

Native Intelligence

Built on the Matter standard with an ESP32-C6 at the core. WiFi 6, Thread, and BLE — all running locally. Your switches work even when the internet doesn't.

Invisible by Design

Every module hides behind the switch plate, inside a standard electrical box. No smart switches to replace. No aesthetic compromise. Your luxury finishes stay untouched.

ESM-140

A single-channel TRIAC dimmer module that adds smart capability to any wall switch — luxury or standard. Wire it inline between your switch and your lights — power in, signal in, dimmed output out. Fits inside a standard US 3.5" deep single-gang back box, completely hidden behind the switch plate.

Auto-detects your switch type: momentary push button, latching toggle, or 0-10V rotary dimmer. Connects to Google Home, Apple Home, and Amazon Alexa simultaneously via Matter over WiFi.

Dry Contact — Momentary

Push Button

Classic momentary push-to-toggle operation. Press once to turn on, press again to turn off. The ESM-140 detects the brief contact closure and toggles the light state. Smart home apps can also control the light independently.

Dry Contact — Latching

Toggle Switch

Traditional toggle that holds position. The ESM-140 follows the physical switch state — flip up for on, down for off. Your smart home platform always reflects the current switch position, and can override when needed.

0-10V + Dry Contact

Rotary Dimmer

Full analog dimming via any 0-10V rotary knob or slider, plus a push button for on/off. Turn the knob to set brightness from 0-100%. The smart home platform can also set levels, and the physical knob always takes priority when adjusted.

Apple Home

Native HomeKit support through Matter. Use Siri, the Home app, and automations. Works with Apple TV as a home hub.

Google Home

Full Google Home integration via Matter. "Hey Google, dim the living room to 50%." Automations, routines, and Nest integration.

Amazon Alexa

Alexa discovers the ESM-140 automatically through Matter. Voice control, routines, and groups — just like any native Alexa device.

01

Wire It

Connect Line, Neutral, and Load on the power side. Connect the switch signal wire on the low-voltage side. Standard electrician wiring — no special tools.

02

Power It

Flip the breaker. The ESM-140 powers up and enters commissioning mode automatically. The status LED pulses teal — it's ready to pair.

03

Scan & Done

Open Google Home, Apple Home, or Alexa. Scan the QR code on the module. The app finds it, joins it to your WiFi, and you're controlling lights in under 60 seconds.

Firmware updates happen over-the-air automatically. The one-time USB-C port is only for the initial factory flash.
