Time Of Use (TOU) metering provides a way for utilities to vary the cost/kWh based on the time of day. This allows them to charge more when the demand is highest, which is typically in the middle of the day. TOU is separated in up to four time periods, each with it's own tariff (cost), which is determined by your Utility and should be included on your monthly statement, if this is the rate structure that you have. More info about TOU can be found on wikipedia here: https://en.wikipedia.org/wiki/Time-based_pricing

Our Omnimeters also have the ability to separate kWh into up to four TOU "buckets" as well (T1,T2,T3,T4). This allows you to set up your submeter(s) so that they log kWh in the same TOU periods that your Utility does. Ultimately this allows you to bill your tenant accurately. The sum of the TOU buckets will equal your overall kWh reading. There are also up to four TOU values for both Total kWh and Reverse kWh.

To set TOU tariffs using the Push3 and your online Push account portal, take a look at this support article.

To set TOU tariffs using the EKM Dash software:

To make changes to the TOU settings with the Dash software you must be reading your meter(s) with the EKM Blink USB Converter. Here are the steps to setting up TOU in your meter:

  1. If you are setting TOU tariffs, it is most likely because your utility bill is broken out by TOU. Your should first familiarize yourself with how exactly your utility company is doing this. What are the time periods for each TOU tariff? Are there different tariff schedules for different seasons, holidays, or on weekends? Having answers to these questions will make it easier to understand your options when you begin to set up these tariffs in Dash.
  2. From the main window in Dash click the meter you would like to edit in the Meters listbox in the upper left.
  3. From the main Dash window, click the "Meters" icon in the upper left corner.
  4. Click "Edit meter..."
  5. Click the "Rates" icon at the top of the window.

  6. Using your utility bill as a reference (TOU breakdown should be included on your bill), enter the time periods for each of up to four TOU buckets (some schedules don't use all four buckets).
  7. If your bill indicates that you have different schedules for seasons, holidays, or weekends, also set the time periods for each of up to four TOU buckets, for each schedule that is indicated on your utility bill.
  8. To assign the appropriate schedule for a season, click the "Seasons" tab at the top of the window.
  9. Set up to four seasons with the appropriate schedule. 
  10. When you are ready, click the "Set" button.
  11. It will prompt you the enter the password. The default password is "0"
  12. It will let you know if changing the setting was successful. If it was, great. If not, try again. It sometimes takes a few tries to complete successfully, especially if you are reading multiple meters with one USB Converter or iSerial (discontinued).
  13. To assign the appropriate schedule for Weekends and/or Holidays, click the "Overrides" tab at the top of the window.
  14. The drop-down lists provided will let you select a schedule for weekends and/or holidays.
  15. When you are ready, click the "Set" button.
  16. To choose the specific dates for holidays, click the "Holidays" button.
  17. Select all of the months and dates for you holidays.
  18. When you are ready, click the "Set" button.
  19. If all of your TOU setting are as you want them, click "OK" to finish.

The TOU kWh values can also be viewed in EKM Dash's main window:

If you have an Omnimeter Pulse v.4 then you can also see these values on the the meter's LCD display. The registers are the numbers 16–23, listed below.
  • 16 = T1 kWh (TOU 1)
  • 17 = T2 kWh (TOU 2)
  • 18 = T3 kWh (TOU 3)
  • 19 = T4 kWh (TOU 4)
  • 20 = Reverse T1 kWh (Reverse TOU 1)
  • 21 = Reverse T2 kWh (Reverse TOU 2)
  • 22 = Reverse T3 kWh (Reverse TOU 3)
  • 23 = Reverse T4 kWh (Reverse TOU 4)
