Energy Charts

The energy charts section of your Live Dashboard shows historical energy data for your Tesla site — letting you spot patterns, review past performance, and understand how your automations affected your energy usage.

Chart types

Grid Getter shows energy data across four time resolutions:

View	Data interval	Maximum lookback
5-minute	Every 5 minutes	Last 7 days
Hourly	Hourly totals	Last 30 days
Daily	Daily totals	Last 90 days
Monthly	Monthly totals	Last 12 months

Switch between views using the tabs above the chart.

What the charts show

Each chart displays several data series that you can toggle on and off:

Solar production — electricity generated by your solar panels (kW or kWh depending on view)
Grid import — power drawn from the utility grid
Grid export — power sent to the grid (selling excess solar)
Battery charge/discharge — power flowing into or out of your Powerwall
Home consumption — your home’s total electricity usage

Reading the data

Positive values represent energy flowing in a particular direction as labeled (e.g., grid import means you’re drawing from the grid).

Battery discharge appears when your Powerwall is powering your home — this is typically what happens during demand periods or peak hours when DemandGuard or a Peak Time automation is active.

Event bands

Periods you have logged as a VPP event or recalibration show on the Power Flow Graph as a band behind the lines, so an odd-looking hour has a label on it. Tesla announces neither kind of event, and we don’t yet know what either one looks like in the data, which is why we ask you to log them.

VPP events are a purple band with solid edges. An event you have not closed yet runs to the right edge of the chart and its label ends in “in progress”.
Recalibrations are a lighter blue band with dashed edges, and the label reads “about 9:30 AM–10:30 AM” because those times are estimates.

Each band carries a small label at the top. Click the label to edit the event or delete it. The band itself does not get in the way: you can drag across it to zoom just as you would anywhere else on the chart.

There are two ways to log an event from the chart:

Click Log event in the Live Dashboard header. The sheet opens with the last hour filled in.
Drag to zoom into the period, then click Log event for this range next to Reset Zoom. The sheet opens with the zoomed start and end already set, including the end date if the range crosses midnight. The button disappears when you reset the zoom or pick a different time range.

History from before you joined

Grid Getter starts recording your energy the moment you connect your Powerwall — so on its own, a chart could only ever reach back to your sign-up date.

It doesn’t stop there. When you pick a range Grid Getter hasn’t recorded in full, it asks Tesla for the missing time and fills it in. Your Powerwall has been keeping this history since it was installed, so a range from before you had a Grid Getter account still has something to show.

While a chart is loading a range Grid Getter hasn’t stored yet, the hours are pulled from Tesla inside the same request. That takes a few seconds, so the loading placeholder shows an animated “Loading historical data” notice rather than sitting silent.

When a chart is using that filled-in history, a line under it says so — for example “68 of 168 points filled in from Tesla, for time before Grid Getter was recording.” It’s worth knowing which is which: filled-in points come from Tesla’s half-hourly summaries rather than Grid Getter’s own readings every few minutes, and they carry no battery percentage.

The filled-in history is saved, so the next time you open that range it loads straight away. A long range fills in over a few minutes — the most recent months arrive first and the rest continue in the background.

Data gaps

If you still see gaps in your chart data, it usually means:

Your Tesla system was offline during that period, so neither Grid Getter nor Tesla has a reading
The data hasn’t finished syncing yet (can take up to a few hours)
Grid Getter’s connection to Tesla was temporarily interrupted

Using charts with automations

The energy charts are a great way to evaluate how your automations are performing. For example:

After setting up a DemandGuard automation, check the 5-minute chart during a demand period to see if battery discharge offset your grid draw
After a Peak Time automation runs, look at the hourly chart to see if your battery reserve was in place during the peak window
Compare daily totals before and after adding automations to measure impact
