Sun Arc History Fix and History Chart Peak Values Fix
Release Date: June 9, 2026
Type: Bug fix release
What's Fixed
Sun arc now shows correct times when viewing a past date (thanks @sg1888)
When scrubbing back to a previous date, the sun arc was still showing today's sunrise, sunset, dawn, dusk, and solar noon times, and the moon phase was always the current phase rather than the phase on the selected date. Solar Sentinel now computes the correct solar event times and moon phase for any past date using the installation's latitude and longitude, which are read automatically from HA's configuration. Today's view continues to use the live sun.sun entity for maximum accuracy. If HA does not expose coordinates, the arc falls back to live values as before.
Panel detail history chart now shows correct peak values in 6m and 1y views
The 6-month and 1-year history views in the panel detail modal were showing power levels far below actual panel output, typically around 30-40% of the real peak. The root cause: those longer ranges use daily statistics buckets, and the chart was plotting the daily mean. The daily mean averages in every hour of the day including nighttime hours at 0W, which dragged the apparent peak down dramatically. A panel producing 280W at noon looks like it maxes out at 80-90W when averaged across a full day.
The 6m and 1y views now plot the daily maximum from HA's statistics instead, which correctly shows the peak power reached each day. This matches the values you see in the 7d, 30d, and 90d views and on the panel cards themselves.
No settings migration needed. Update via Settings > Add-ons > Solar Sentinel > Update and refresh the page.
