How to Set Up StopWatt and Track Your Electric Bill

The best way to try StopWatt is to measure your own electricity use before and after. Here is a simple plan that fits inside the 60-day guarantee period.

Step 1: Take a "before" reading

Before you plug in StopWatt, write down:

• today's date and your electric meter reading in kWh;
• the kWh on your last bill and on the same month last year.

Your bill is based on kWh (kilowatt-hours), so kWh is the number to watch.

Step 2: Plug it in

• Plug StopWatt into a standard wall outlet, centrally or near the breaker box.
• Use one unit for every 800 to 1,200 sq. ft.
• Check that the green light is on, and leave it plugged in.

Step 3: Compare fairly

Weather changes your bill a lot, because heating and cooling are about half of a typical home's energy bill (ENERGY STAR). For a fair comparison:

• compare the same billing period this year and last year;
• read your meter at the same time of day each week;
• note any big changes, like a heatwave or new appliance.

Step 4: Decide within 60 days

StopWatt's guarantees run for 60 days from delivery:

Set a reminder on your phone for day 50, so you have time to decide.
