Real-Time Aggregated Power chart

What this widget is for

The Real-Time Aggregated Power chart is the streaming, live-updating sibling of the Power Analytics chart. As new samples arrive from the plant, the chart scrolls right and draws them — no clicking, no reloading. Use it when you want to watch the system in real time: solar coming up at sunrise, load steps as equipment switches on, the battery responding to a grid disturbance.

For today, but not strictly live use the Power Analytics chart. For what totalled across a period use the Energy Production & Consumption chart. For one specific device's history use the Device Historical Analytics chart.

Companion guides

• Dashboard overview — how to add, move, resize, and remove widgets.
• Power Analytics chart — the historical sibling of this widget. Same series, but for an arbitrary past day.
• Live status icons — the single-value live readouts that pair well with this chart.
• Power Flow widget — the animated flow diagram of these same numbers.

Where to find it

Open the Dashboard, click the pencil icon to enter edit mode, then click Add New Widget. Search the picker for Real-Time Aggregated Power and click Add Widget.

The chart at a glance

A small toolbar sits in the top-right of the chart, and the chart area itself shows recent values with new samples appearing on the right as they arrive. There is no date picker here — by design, the chart is always anchored to "now" — and the time axis scrolls past as the day progresses.

A legend along the bottom lists the active series; click an entry to hide or show that series without changing settings.

Choosing what to plot

Open the gear icon. The settings dialog has:

• Title — the header text shown above the chart.
• Data Interval — how dense the points should be on the chart (see below).
• Series toggles — twelve streams you can show or hide:
  • Grid W / Grid VA — grid power (real / apparent).
  • Gen W / Gen VA — generator power.
  • Load W / Load VA — site load.
  • PV W / PV VA — solar production.
  • Storage C W / Storage C VA — battery charging power.
  • Storage VA — battery storage power.
  • Storage % — battery state of charge.

Tick the streams you want; the chart redraws live. As new samples arrive they're appended to the right edge in the chosen interval.

Picking a data interval

The Data Interval controls how densely the live samples are plotted:

• Smaller intervals show every twitch of the signal — useful for short bursts of investigation.
• Larger intervals smooth the line — useful when you want the overall shape without noise.

The default is set to a sensible middle value. Bump it down only briefly when hunting a transient, then return it to the default to avoid an overly busy chart.

Reading the chart

• The chart scrolls. New samples appear on the right; old samples leave on the left. The visible window is "the last N minutes" depending on the data interval.
• Hover anywhere along the chart to see a tooltip listing every series at the hovered time.
• Click the chart to pin the tooltip in place; click again to unpin.
• Two y-axes appear when you mix streams with different units. Power streams (W / VA) share an axis; Storage % takes its own axis (0–100 %).
• A gap on a line means no data for that window — sensor offline, network glitch, etc. The chart deliberately leaves the gap so missing data doesn't look like "true zero".

Who can do what

• Any signed-in user can add the chart, switch series on or off, change the data interval, and read the live values. The chart is read-only — it never sends a command back to a device.

Common issues

• The chart hasn't moved in a while. New samples aren't arriving. The Auto Update option in your View Settings controls a periodic background refresh — leave it on so the live stream reconnects after a glitch.
• One series is flat-lining at zero. Either that stream genuinely is at zero (e.g. PV at night, generator while off) or its data field isn't being reported on this site. Switch it off so it isn't carrying a dead line.
• The chart looks like history, not live. Confirm the dashboard's Auto Update is on. Without it, this chart still streams but the dashboard-level refresh that keeps it in sync with the rest of the page is off.
• Storage C and Storage series both show similar values. Storage C is charging power; the plain Storage is all storage activity. On a battery that's currently charging they overlap; while discharging the plain Storage shows the discharge and Storage C is zero. Switch off whichever you don't need.

Tips and gotchas

• Use it as a "live monitor" widget. Drop it onto a View dedicated to monitoring (paired with the Power Flow widget and a row of live icons) and leave it open on a wall screen.
• Don't confuse this with the Energy chart. This widget shows power (kW / kVA), not energy totals (kWh). A flat line at 0 means no power is flowing, not "no energy was used today".
• Two charts on one View work well. Drop the Power Analytics chart and this Real-Time chart on the same View — historical context on one, the live feed on the other.
• The series toggle list is bigger than Power Analytics's. This chart has separate Storage C (charging) series in addition to the general Storage stream — useful when you specifically want to highlight charging behaviour.
