Smart Plugs | Products

Overview

SGT Smart Plugs turn any wall outlet into a metered, app-controlled, schedule-aware power point — with real-watts measurement, surge protection, over-current cutoff and an away-mode randomiser that makes the house look lived-in while you’re away.

Drop one in between the wall socket and a geyser, AC, TV stack, fan, router or kitchen appliance and you immediately get on/off control from the app or voice assistant, a running tally of kWh and cost, and instant push alerts if the load drops out (geyser turned itself off) or spikes (something drew more current than usual). No wiring, no electrician, no rewiring of the socket.

Real-watts metering — volts, amps, watts, kWh, cost (60 Hz sampling)
Surge clamp 1200 J + over-current and over-temperature cutoffs
Schedules & rules — time-of-day, sunrise/sunset, standby auto-off
Away-mode randomiser — geofence-aware on/off pattern that mimics occupancy

How It Works

The diagram above shows how the plug sits between the wall and your appliance, measures every cycle of AC, and reports back to the cloud and your phone in seconds. Hover any module to see its live telemetry.

The plug — UK/EU/US blade, internal relay rated 16 A, on-board CT-coil current sensor, LED ring shows on/off and load colour.
Metering & safety — on-board MCU samples AC at 60 Hz, runs MOV surge clamp, over-current trip and 85 °C thermal cutoff locally.
Cloud & cost — energy is rolled up daily and monthly, priced against your local tariff, and exposed to rules (e.g. IF standby > 5 W for 10 min → OFF).
App / away-mode / alerts — control from anywhere, get push alerts on unusual load, and let geofencing flip the house into “looks lived in” randomiser when you leave.

The green stream along the bottom is the live command channel — relay state, schedule changes and away-mode rules flowing back to every plug.

Features

Real-time metering — V, A, W, PF, frequency, kWh, cost
Surge protection — 1200 J MOV clamp, status indicator
Over-current cutoff — 16 A trip with auto-reset window
Thermal cutoff — relay temp monitored, shuts down at 85 °C
Schedules — time-of-day, sunrise/sunset, day-of-week, count-down timer
Standby auto-off rule — drop power to vampire loads (TV, console, charger)
Away-mode randomiser — configurable per-plug, geofence-triggered
Anomaly alerts — push you if the load disappears or spikes outside its norm
Child-lock — disable the physical button to prevent accidental toggling
Voice control — Alexa, Google, Apple Home (Matter)

Use Cases

Geyser timer — 30-minute heat-up before shower, no leaving it on all day
TV/console standby cutoff — drops vampire load every night at 23:00
Holiday away-mode — lights and TV randomly switch through the evening
AC scheduling — turn AC on 10 minutes before you get home (geofence)
Iron / hair-tool safety — auto-off if left on for > 20 min
Server / NAS reboot — power-cycle remotely if the device stops responding
Small business energy audit — meter and bill back per-appliance kWh
