This driver produces metrics based on user defined energy consumption within a specified demand (time) window and instantaneous power reading from a connected power/energy meter. The resulting values can be used to drive demand shift automation in order to stay under demand window limits.

Name - The name is up to the user. Our suggestion is to choose a naming convention that makes the viewing the device list intuitive. Such as referring to the sensor and/or application. Keep the name short as it will be combined with the register name to create the default “Field” name (if added to “Fields”)

Active Check box - Check this box and “Save changes” to run the driver. The driver program can be suspended by unchecking the box and clicking on “Save changes”.

User Notes - This space can be used to store information specific to the device, such as: location, wiring, scaling, etc.

eze System Notes - In this space we provide: wiring instructions, product image, product details.

Window size - Select the number of minutes in your demand window (5, 10, 15, 20, 30, 60)

Delta-T for trend -

Power field - Enter the Field number for the power (kW) reading

Driver info - Typically this is the name from the program file

Driver updated/version - Date loaded or updated and the version of the driver

Battery & Signal - Signal indicates the progress through the script. If driver fails to operate, signal number indicates progress

Driver status - Color and text of status bubbles give a quick visual reference of Communication, Operation, and Application

Communication - Com count indicates number of successful and unsuccessful data packets received

1. Target Energy (Writable) - User defined max energy consumption for demand window
2. Predicted Energy - Predicted energy total based on accumulated energy and current power usage
3. Window energy - Current energy total for current window
4. Momentary power - Current power (kW) reading of user define Field
5. Max power allowed - Max sustained average power consumption allowable to stay within demand window limit.
6. Power margin - Head room between current power reading and “Max power allowed”.
7. Time until target exceeded - Predicted elapsed time when user define target energy total will be exceeded, based on accumulated energy and current power usage
8. Window time remaining - Seconds remaining in demand window
9. Time over power budget - Number of seconds over user defined max energy, in current window.
10. Percent of previous window - Percentage comparison of current consumption to previous demand window.
