  • Vehicle charging (kW)

Toggle individual data series on or off by clicking their legends.

Your daily energy data will appear here

Rows can be sorted by any column. Click a date row to zoom the chart to that specific day.

Day Comparison

The Compare tab lets you pick any two dates and see their energy totals side by side. Each metric shows a delta indicator — green when the change is favorable (more solar, less grid import) and red when it’s not.

How to use it

  1. On the History page, switch to the Compare tab (iOS) or scroll to the Day Comparison section (web)
  2. Pick two dates using the date pickers — defaults to yesterday vs today
  3. View side-by-side totals for Solar, Home, Imported, Exported, Battery Charged, and Battery Discharged
  4. When today is selected, a Solar Forecast row shows your full-day forecast and current pace

Yesterday summary

Both the iOS and web dashboards include a compact “Yesterday” card showing the previous day’s key metrics at a glance. Tap it to jump to the full comparison view.

Use cases

  • Morning check: see yesterday’s full summary and compare against today’s forecast
  • Seasonal comparison: pick the same date from last month to see how production has changed
  • Before/after: compare the day before and after a system change (new panels, battery settings, etc.)
