Analysis

Welcome to the brain of your smart home. This section helps you move past simple "on/off" states and into deep insights. Whether you're trying to figure out why your electric bill spiked or why the bedroom is always cold, here is how to use Constant Graph like a pro.

Types of Analysis You Can Perform

With ConstantGraph, you aren't just looking at dots on a line; you’re performing "forensic home audits." Here are the primary ways to analyze your data:

1. Energy Disaggregation

This is our flagship analysis. By taking data from a single Whole Home Energy Meter, we can "disaggregate" the signal to identify individual appliances.

  • What it does: Identifies the "signature" of high-load devices (like your kettle, EV charger, or dryer) even if they aren't "smart" themselves.
  • Analysis Goal: Determine exactly which appliance is the "energy hog" without needing a smart plug on every outlet.

2. Temporal Aggregation

Raw data is often noisy. We use mathematical functions to clean it up so you can see the forest, not just the trees.

  • Sums & Totals: View energy usage by the hour, day, or month to track your budget.
  • Averages (Weighted): Understand the "normal" temperature or humidity of a room over a week, filtering out brief spikes from a door opening.
  • Min/Max Tracking: Identify extreme outliers, such as the coldest point of the night or the highest voltage surge.

3. Correlation Analysis

Graphs become powerful when you overlay different types of data.

  • Environmental vs. Energy: Overlay outdoor temperature against HVAC energy usage. Does a 5°C drop outside lead to a 20% spike in heating?
  • Occupancy vs. Activity: Compare motion sensor data with lighting or TV power draw to see if "Auto-Off" routines are actually working.

4. Operational Benchmarking

Establish a "baseline" for your home.

  • Trend Comparison: Compare this month’s data against the same month last year.
  • Duration Analysis: Analyze how many minutes per day your fridge compressor is running. A steady increase over months could signal a failing motor or a worn-out door seal.
