Useful Automation, Not More Admin

The modern smart home market often sells fragile novelties: cloud-dependent light bulbs that refuse to illuminate when the broadband line drops, smart refrigerators with touchscreen ad dispensers, and voice assistants that misunderstand plain requests.

The Three Inflexible Rules of Domestic Tech

Before installing any automated controller, valve, relay, or sensor, we subject the hardware to three strict criteria designed to protect household serenity.

  1. 01

    The "Visiting Relative" Baseline

    If a houseguest, babysitter, or elderly parent requires an operating manual or a smartphone app just to adjust the living room light or run hot water, the installation has failed. Physical toggles must always function instantaneously, regardless of server states.

  2. 02

    Local Control Over Cloud Tethering

    All telemetry and command packets must route over local radio meshes: Zigbee 3.0, Z-Wave Plus, or Thread via Matter. If the external WAN cable is severed, every scheduled lighting cycle, thermostatic check, and water leak sensor must continue running unimpeded.

  3. 03

    Predictable Failure Modes

    When a motorized radiator valve battery depletes, does it fail open to keep the room warm, or does it lock frozen in the dead of winter? Smart hardware must be selected based on how gracefully it behaves when it breaks.

High-Value Automations That Truly Earn Their Place

We disallow gimmick triggers (like flashing lights blue when someone rings the bell) in favor of high-leverage physical protection and environmental stability:

SYS.01

Main Shutoff Water Sentinel

A motorized motorized ball valve on the incoming main water supply paired with five floor-level moisture probes (under sink, behind washing machine, under boiler). Shuts down mains water within 1.2 seconds of moisture contact.

Averts catastrophic water damage
SYS.02

Relative Humidity Bathroom Extraction

A dual-speed centrifugal extractor controlled by a differential humidity sensor. Automatically switches to high exhaust when shower vapor spikes, shutting down only when ambient moisture reaches equilibrium.

Prevents grout mold formation
SYS.03

Circadian Color Temperature Shifting

Local smart dimmer relays that shift ambient ceiling LED temperatures smoothly from 4000K daylight at noon down to 2200K amber glow by 21:00, without changing physical wall switch behavior.

Protects natural sleep cues
"Automate the repetitive chores you forget, not the tactile actions you enjoy. Opening your living room curtains by hand should feel good; checking boiler pressure shouldn't require manual memory."
