Issue
Home Assistant dashboards load but do not receive live updates on FullPageOS 0.14.0.
Fix / Workarounds
Adding these Chromium flags in
/opt/custompios/scripts/start_chromium_browser
restores live updates:
flags=(
...
--disable-background-timer-throttling
--disable-renderer-backgrounding
--disable-backgrounding-occluded-windows
)
Notes
Chromium seems to throttle background/occluded windows in kiosk mode, which breaks Lovelace real-time updates.
