11 9 3.3 Interpreting Data 1. Observe current electricity demand with the animated, colour- changing gauge at the top of the WUI. The position, colour and numerical value associated with the gauge will change in real- time as electrical appliances are turned on and off in your home. The maximum value of the gauge is updated every 24 hours based on your home s peak demand. Current demand in watts Peak demand from the previous day Figure 12 Current Demand Gauge 2. Observe your current spending rate with the text box located below the gauge. This value will change according to your home s electricity demand and current pricing tier (explained later on in Step 5 of this section). Current amount of money being spent per hour Figure 13 Current Spending Text Box

12 10 3. Observe the amount spent during each hour of the current day with the bar graph at the bottom of the WUI. This bar graph will be updated every hour, on the hour and reset every morning at 1:00 am. Amount spent in dollars Hourly periods from current day Figure 14 Hourly Spending Bar Graph 4. Observe the amount spent during each day of the current week with the bar graph at the top, right corner of the WUI. This bar graph will be updated every day at 12:00 am and reset on Monday morning. Amount spent in dollars Daily periods from current week Figure 15 Daily Spending Bar Graph

13 11 5. Observe the current pricing tier and price/kwh with the indicators in the bottom right corner of the WUI. These values will be updated whenever the pricing tier and price/kwh changes. Current price per kwh Figure 16 Current Price and Tier Current pricing tier

14 12 4. Iota Wireless Display The Wireless Display is like your home s electricity speedometer. This gauge- like device is meant to be placed somewhere in your home where it will be very visible. The more often you look at the Wireless Display the more money you will save! Figure 16 Wireless Display 4.1 Turning on and Reading the Wireless Display 1. Turn on the Wireless Display using the power switch located on the back. If you have set up the Iota Base Station correctly, the Wireless Display should now automatically connect to it and begin displaying you how much money you are currently spending on electricity. If the Display doesn t turn on, it may need to be charged. Follow the steps in Section 4.2 to do this. Figure 17 Power Switch

15 13 2. Observe current electricity demand with the analog gauge. The position of the orange needle gives you a quick, at- a- glance, indication of how much money you are spending on electricity. If the needle is all the way to the left and the gauge is glowing green, then you are only using a little electricity (that s good!). If the needle is all the way to the right and the gauge is glowing red, then you are using a lot of electricity (that s not good). The furthest position to the right corresponds to the maximum instantaneous demand of electricity that your Iota system has ever recorded for your home. 3. Observe your current spending rate with the digital OLED display. The OLED display below the gauge shows the exact amount of money being spent on electricity per hour. If the display reads $1.00/h for example, that means that the total amount of electricity being consumed by all of the loads in your home at that moment amounts to a cost of $1.00 per hour. If you left all of the electrical devices in your home in this same state for 5 hours, you will have used $5.00 worth of electricity. 4.2 Charging the Wireless Display When the Wireless Display s battery is low, you will see a B appear in the top right- hand corner of the Iota wireless display s OLED screen. This indicates that it is time to charge the Display. Low battery indicator Figure 18 Low Battery Indicator

16 14 1. Place the Wireless Display in its cradle on top of the Base Station. The red charging light on the Base Station will turn on to show that the battery is being charged. Leave the Iota wireless display on the base station until the red charging light turns off. Charging indicator light 2. When the red charging light turns off, remove the Wireless Display from the Base Station. It is not necessary to remove the Iota Wireless Display from the Base Station when it has finished charging. If you have found a convenient location in your home for the Base Station, then you may leave the Display on top of it and never have to worry about charging. 4.3 Using the Wireless Display to Determine the Cost of Running an Appliance. 1. Power down or unplug the appliance in question from the wall outlet. 2. Write down the cost per hour from the Iota Wireless Display while the appliance is powered off. 3. Plug in the appliance and turn it on. Figure 18 Low Battery Indicator 4. Wait for the Wireless Display to update, and then write down the new cost per hour. 5. Subtract the initial cost per hour from the cost per hour seen while the appliance is running. This difference is the cost per hour of running that particular appliance. Try this with any electrical load in your home to find out how much it costs you to run!
