Fault & Anomaly Detection

Catch It Early.
Find the Cause.
Fix It Fast.

SmarterHU continuously watches every parameter across your HVAC system — detecting anomalies before they become faults, and diagnosing faults before they become complaints. Less downtime. Less waste. Happier occupants.

The Problem

Every minute a fault goes undetected, you pay for it.

Energy climbs silently. Comfort degrades slowly. Then the complaint comes — and by then, half a day is gone before someone even identifies the cause, let alone fixes it.

01. Silent Energy Waste
A choking filter, a refrigerant leak, or a sticking actuator can raise energy by 20–30% for weeks — completely invisible without continuous monitoring.
02. Complaint-Driven Discovery
Most faults are discovered when an occupant complains — by which time comfort has been compromised for hours, and the fault may have compounded.
03. Slow Root Cause Diagnosis
Without data, technicians spend hours checking systems manually to find the cause — often on a hunch, not evidence. Time and money lost on every call-out.
04. No Cross-Site Comparison
When one office uses 40% more energy than a comparable one, it goes unnoticed without benchmarking — a persistent leak in performance that never gets plugged.
05. Temperature Targets Missed
Supply air not reaching setpoint. Return air warmer than expected. Zone temperatures drifting. Each a symptom — but of what? Without data, nobody knows.
06. Long Resolution Time
Fault reported → call logged → technician dispatched → cause found → part sourced → repaired. Without early detection, every step takes longer.
How Detection Works

From signal to resolution — automatically.

SmarterHU’s detection engine works continuously across all connected HVAC equipment — learning normal, spotting deviation, tracing cause, and dispatching the right action.

Continuous Data Stream

Every sensor — temperature, pressure, current, flow, air quality, energy — streams data every 60 seconds from every connected equipment.

Baseline Comparison

Each reading compared to the equipment's own historical baseline — adjusted for weather, time, occupancy, and load. Not a generic threshold.

Anomaly or Fault Classified

Deviations classified by type and severity. Related signals cross-referenced to build a root cause chain — symptom vs. underlying cause.

Alert with Action

The right person receives an alert — what happened, where, why, what to do. Resolution clock starts immediately, not when someone notices.

Platform Capabilities

Everything needed to detect, diagnose, and resolve.

SmarterHU’s fault and anomaly engine covers energy, air quality, temperature, equipment, and cross-site performance — in one integrated platform.

Energy Anomaly Detection

Compares real-time energy against last week, last month, and peer offices — flagging deviations the moment they appear, weather-adjusted and load-normalised.

Fault Detection & Instant Alerts

Hard failures — trips, cooling loss, flow failures, sensor outages — detected the instant they occur. Alert includes equipment ID, location, fault type, and action.

Real-time · Actionable

Automated Root Cause Analysis

Every anomaly comes with a causal chain — from the observed symptom back to the underlying driver. Technicians arrive knowing the answer.

Causal chain · Auto-built

Temperature Setpoint Tracking

Monitors whether every zone and supply air point is achieving its setpoint — flags when it consistently falls short, with root cause analysis attached.

Zone · Supply air · Delta-T

Air Quality Anomaly Detection

Watches all 7 IAQ parameters for gradual degradation — catching slow damper sticking, filter clogging, and fresh air issues before they breach thresholds.

CO₂ · PM · TVOC · 7 params

Cross-Site Benchmarking

Identifies when one office's performance diverges from comparable peers — surfacing hidden inefficiencies invisible if each site were viewed in isolation.
