The EKM Dash software supports different Time Of Use periods that you can set in accordance with your electricity utility provider's time of use rates.
The meter can keep track of four separate TOU tariffs (T1,T2,T3,T4) to calculate the energy used at different periods of time. For example if your power is more expensive from 1PM to 7PM and it is cheaper from 7PM to 11PM, the meter can keep track of these different periods of time. It can be set for up to 4 time periods per day and it can specify the tariff for that period (from T1 to T4). The meter date and time can be set by RS-485 communication. This can be done in the EKM Dash software.
To access this in the Dash software:
- Open the EKM Dash
- Select your meter
- Click the Meters icon
- Click "Edit Meter"
- Click the Rates icon
- Enter your tariffs and corresponding times here. These should be provided by your utility company. Often times these appear on each utility bill.
- Some utilities apply different cost/kWh for not only the time of day but for the day of the week or specific day of the year. Schedules allow you to set up different tariffs for different seasons, holidays, and/or weekends.
- The Seasons, Holidays, and Overrides tabs allow you to apply the different Schedules that you set up.
- Make sure that you also set the meter's internal clock to the local time of the meter, as this is the clock that is used to determine which TOU tariff the meter should record to at any given moment.
