Alarming

Alarms by location

Behavior

The display shows a message saying that the selected location has no direct child locations.

Probable cause

The Alarms by location display shows the number of alarms Energy Hub detected for the direct children (locations or equipment) of the item selected in the organization tree. For example, if you select a building that has floors configured in Energy Hub, the display shows the alarm counts for the floors. If you select a location without direct children, then there is nothing to display, and it shows the "No direct child locations" message instead.

Actions

No actions are required. Energy Hub behaves as expected.

If the location you selected in the organization tree has children (locations or equipment) in your-real life facility that you want to monitor, then install monitoring devices for these children, add them to your Energy Hub system, and configure them in Energy Hub. For information on organization models in Energy Hub, see Organizations.

Examples

The following shows the display for a location without direct child locations and with direct child locations:

Without direct child locations

With direct child locations – The selected location in the organization tree is a site. The child locations are buildings that are configured directly below the site in Energy Hub.

Functionality

Energy Code Compliance

Energy consumption by usage type

Behavior

The display shows a message saying that the display is not available because only Total energy has been configured for the selected location.

Probable cause

The energy consumption by usage type display shows energy consumption categorized by energy usage types for the selected location in the organization tree. For example, if you select a floor, it might display consumption for lighting, heating, and other usage types for this floor.

Energy Hub calculates consumption by usage types based on the loads and usage types for the selected location. The message that is displayed shows that only Total energy has been configured for this location. Total energy is a supply usage type. You need to configure at least one load usage type for this location. For more information on usage types, see Usage types.

Actions

Confirm that monitoring devices for the loads in the selected location are available in Energy Hub. Add the monitoring devices to the location and assign energy usage types, then try viewing consumption for this location again. For information on how to add devices to a location and assign usage types, see Adding loads and supplies and assigning energy usage types.

If you cannot resolve this issue, contact Technical Support.

Examples

The following example shows a location that has only the Total energy usage type configured. The display shows a "not available" message.

The following example shows the same location with load energy usage types configured. The display shows the consumption by usage type for this configuration.

Behavior

The display shows a message saying that the selected location has no direct child locations.

Probable cause

Energy consumption by location, Energy intensity by location, and Water intensity by location show energy consumption, energy intensity, and water intensity for the direct child locations of the item selected in the organization tree. For example, if you select a building that has floors configured in Energy Hub, the displays show the energy consumption and intensity or water intensity for the floors. If you select a location without direct child locations, then there is nothing to display, the "No direct child locations" message is displayed instead.

Actions

No actions are required. Energy Hub behaves as expected.

If the location you selected in the organization tree has child locations in your-real life facility that you want to monitor, then install monitoring devices for these locations, add them to your Energy Hub system, and configure those child locations in Energy Hub. For information on organization models in Energy Hub, see Organizations.

Examples

The following shows the display for a location without direct child locations and with direct child locations:

Energy intensity

Water intensity

Behavior

The display shows a message saying that no floor area has been configured for the selected location.

Probable cause

No floor area has been set for the location. Energy Hub uses the floor area to calculate energy and water intensity. The floor area can be set for any location in the organization tree. Energy Hub aggregates and rolls up floor area of child locations to the parent. For more information on intensity and floor area, see Intensity.

Actions

Set the floor area for the selected location. For information on how to set the floor area for a location, see Setting the floor area for a location.

If you cannot resolve this issue, contact Technical Support.

Examples

The following shows a location that does not have a floor area configured. The display shows a "no floor area configured" message.

The following shows the same location with the floor area configured. The display shows the energy intensity for the location.

Functionality

Trends gadget

Behavior

Trends shows data (lines in the chart) for periods when communications with the monitoring device was interrupted.

Example:

Device communications was interrupted during the time period marked with the red rectangle in the screen capture below.

Probable cause

Energy Hub does not display new data points while communications are interrupted. After device communications are re-established, Energy Hub starts showing new data, and it visually connects the first new data point with the last data point before the interruption.

For cumulative energy data, Energy Hub calculates the difference between the first new energy value after the interruption and the last energy value before the interruption and displays it as interval data for the time when communications were re-established. This leads to a onetime spike in the energy trend.

The table below shows how the Trends display handles load related measurements (current, energy, demand, power factor) when the gateway, the monitoring device, or the load are interrupted:

Scenario	Trends display and CSV file export
Gateway: ON Device: ON Load: OFF	"0" values during the outage. Non-zero values when the load is back on.
Gateway: ON Device: OFF Load: ON	No values during the outage. The last known value is shown with its timestamp in the display. Non-zero values when the load is back on. The last known and first new values are connected in the display.
Gateway: OFF Device: ON Load: ON	No values during the outage. The last known value is shown with its timestamp in the display. Non-zero values for instantaneous measurements and spikes for cumulative (energy) measurements when the load is back on. The last known and first new values are connected in the display.
Gateway: OFF Device: OFF Load: ON	No values during the outage. The last known value is shown with its timestamp in the display. Non-zero values when the load is back on. The last known and first new values are connected in the display.

Actions

No actions required. The system operates as designed.

Functionality

Trends

Behavior

Energy trends oscillate between zero and non-zero values for energy data that is older than a certain date.

Probable cause

A Panel Server gateway with data logging (PAS800) is used to collect data from monitoring devices and sensors. This gateway was set up as a standalone energy server before it was connected to Energy Hub. As a standalone server, the data logging rate for Panel Server was set to an interval that is longer than the interval used by Energy Hub.

When Panel Server was connected to Energy Hub, its data logging rate was automatically changed to a shorter, five-minute interval, the interval used by Energy Hub. After the change in logging rate, Panel Server automatically converted its historical data into a data set with five-minute intervals. The old data was aligned with the new five-minute interval based on timestamps. Panel Server filled the gaps in the new data set by duplicating the last data points before the gaps.

Since Energy Hub displays incremental energy consumption over time, not cumulative energy, it calculates the delta between the current energy value and the previous value. This causes zero energy data points for the data inserted by Panel Server to fill the gaps.

The following shows an example:

Original Panel Server data log with 10-minute cumulative energy data:

8:00	500 Wh	Measured value
8:10	1000 Wh	Measured value
8:20	1500 Wh	Measured value
...

New Panel Server data log, converted to 5-minute cumulative energy data:

8:00	500 Wh	Measured value
8:05	500 Wh	Repeated value
8:10	1000 Wh	Measured value
8:15	1000 Wh	Repeated value
8:20	1500 Wh	Measured value
8:25	1500 Wh	Repeated value
...

Energy Hub data log with incremental energy data:

8:00	500 Wh
8:05	0 Wh
8:10	500 Wh
8:15	0 Wh
8:20	500 Wh
8:25	0 Wh
...

Oscillating energy trend display:

Actions

No actions required. The system operates as designed. This behavior only affects data that was recorded by Panel Server before it connected to Energy Hub. Data recorded after Energy Hub connected to Panel Server will be displayed without the oscillation.

Functionality

Trends gadget

Behavior

Energy values shown in the energy trend fluctuate even if the load is constant.

Example:

Probable cause

Monitoring devices log cumulative energy values. Communication gateways read the logged data from the devices at certain intervals. Differences in device logging rates and gateway update intervals, or communication delays and short interruptions between the gateway and the device, can cause variations in the data flow.

Energy Hub receives the cumulative energy data from the gateways. It then calculates the delta between the current cumulative energy value and the previous cumulative value and displays incremental energy consumption over time. Variations in the data flow can lead to a periodic over or under reporting of the energy consumption. This causes the energy trend to fluctuate. The fluctuations even out in consecutive intervals. See Trends: Energy trend for PowerTag Rope fluctuates. for a related troubleshooting case.

Actions

No actions required. The system operates as designed.

Functionality

Trends gadget

Behavior

Energy values for PowerTag Rope fluctuate even if the load is constant.

Example:

Probable cause

A Panel Server gateway is used to collect data from the PowerTag Rope device. The update interval of Panel Server is different from the data logging rate of the PowerTag Rope. The difference leads to a periodic over or under reporting of the energy consumption.

Since Energy Hub displays incremental energy consumption over time, not cumulative energy, it calculates the delta between the current energy value and the previous value. This causes the energy trend to fluctuate. The fluctuations even out in consecutive intervals.

The following shows an example for a 5 kW load (energy consumption = 250 Wh / 3-minute interval):

Time	PowerTag Rope cumulative energy reading [Wh]	Panel Server cumulative energy reading [Wh]	Energy Hub incremental energy trend [Wh]
8:00	0	0	0
8:01
8:02
8:03	250
8:04
8:05		250	250

Analysis:

• PowerTag Rope measures cumulative energy and logs its measurement data every 3 minutes.
• Panel Server records the logged cumulative energy data from PowerTag Rope every 5 minutes.
• Energy Hub calculates incremental energy data from the Panel Server data logs.
• The incremental energy data in Energy Hub fluctuates caused by the difference in logging rates between PowerTag Rope and Panel Server.
• The fluctuations even out in consecutive intervals.

Functionality

On-site generation monitoring

Electricity cost

Energy flow

Energy consumption (and generation)

Behavior

The displays show on-site generated energy as grid consumption instead of local generation.

Probable cause

The device monitoring local consumption has been wired in reverse. Energy Hub expects the device that is monitoring local generation to be wired as a supply monitoring device. A supply monitoring device has its current instrument transformers (CTs) connected so that it measures generated energy as delivered (positive) and consumed energy as received (negative). If the CT connections are reversed, Energy Hub shows generated energy as consumption and consumed energy as local generation for this device. You can verify this by checking the Energy consumption (and generation) for the device in the Energy view in Energy Hub.

Actions

Confirm that the device has been wired in reverse. If possible, correct the CT wiring for the device. It that is not possible, set the Meter wiring is reversed setting for the device in Energy Hub to Yes. For information on how to change device settings, see Editing device settings.

If you cannot resolve this issue, contact Technical Support.

Functionality

On-site generation monitoring

Energy consumption (and generation)

Behavior

The display shows all the locally generated energy as used locally for a site. The energy sent to grid is always shown as zero.

Probable cause

Assuming that the site is actually sending energy back to the grid, a possible cause for the display showing zero is that the Total energy usage type has not been configured for the site. Total energy is a supply usage type that identifies energy supplied by the utility grid. Energy Hub uses the utility supply information to determine how much of the generated energy was used locally and how much was sent back to the utility grid. For more information on Total energy, see 'Total energy' usage type.

Actions

Configure Total energy for this site. For information on how to configure a usage type, see Adding loads and supplies and assigning energy usage types.

NOTE: You need monitoring devices for the incoming utility feeders for your sites. Without these monitoring devices, you cannot configure the Total energy usage type for a site.

If you cannot resolve this issue, contact Technical Support.

1. The type of device does not provide status information, or
2. No main (incoming) device has been defined, or
3. More than one main (incoming) device has been defined, or

Probable cause

1. The selected device or equipment type does not provide the required measurement data. The Equipment status shows power system data, such as voltage, current, and status. Which data is displayed depends on the type of equipment or device. Some device types, such as virtual devices, do not provide any data.
2. No main (incoming) device has been assigned. For panelboards, the display shows the data for the device monitoring the main (incoming) supply of the panelboard. If no main (incoming) device has been assigned, then the display does not show any data.
3. More than one main (incoming) device has been assigned. For panelboards, the display shows the data for the device monitoring the main (incoming) supply of the panelboard. If more than one main (incoming) device has been assigned, then it does not show any data.

Actions

1. No actions required. Energy Hub behaves as expected. The selected device or equipment type does not provide data that could be displayed.
2. Assign the device that is monitoring the supply of the panelboard as main (incoming). For information on how to assign device context for a device, like main (incoming), see Assigning device context for panelboards.
3. Unassign all but one device as main (incoming) for the panelboard. There should only be one main (incoming) device for a panelboard. For information on how to unassign device context for a device, like main (incoming), see Unassigning device context for panelboards.

If you cannot resolve this issue, contact Technical Support.
