Reading a whole-home energy monitor like a pro

What you’ll need

• A licensed electrician for installation
• Your latest electricity bill
• The monitor's app

Step by step

1. 1

   Have the clamps installed professionally

   Current transformer clamps go inside the electrical panel. This is work for a licensed electrician in almost every case.

2. 2

   Enter your real cost per kWh

   Divide your bill total by the kWh used to get the all-in rate including delivery charges, and enter that figure.

3. 3

   Label every circuit

   Walk the house switching things on and off while watching the live feed until each channel is correctly named.

4. 4

   Establish a baseline

   Note the overnight floor — what the house draws with everyone asleep. That is your always-on load.

5. 5

   Verify each upgrade

   After any change — LEDs, a thermostat schedule, a new fridge — compare the same week against the baseline.

Energy-saving tips

• A rising overnight baseline usually means a failing appliance or a new always-on device.
• Circuit-level data finds the waste that plug-in meters physically cannot reach: HVAC, water heater, oven.
• Export monthly data so you can compare seasons rather than reacting to single days.
