Release Date: June 11, 2026
Type: Bug fix release
What's Fixed
All times now reflect the HA server's timezone, not the browser's
Every timestamp in Solar Sentinel: sunrise, sunset, dawn, dusk, the sun arc time labels, the time slider, the production chart, the grid chart, and the battery chart, was being rendered in the browser's local timezone. For most users the browser and the HA server are in the same timezone, so this was invisible. For anyone accessing Solar Sentinel from a different timezone, times were shifted by the offset between their browser and the server, making the arc and charts appear incorrect.
Solar Sentinel now reads the HA server's timezone at startup and uses it consistently for all time math and display. The array is at a fixed physical location; all times should reflect that location, not wherever you happen to be viewing from.
Weather forecast is now hidden when viewing a past date
The today and tomorrow weather icons in the sun arc margins were appearing even when scrubbing back through historical dates. Since HA only exposes the current forecast and stores no historical weather data, the forecast icons had no meaningful data to show on past dates. They now appear only when viewing today.
