LCARdS 2026.05.09.1

Released May 9, 2026GitHub release

New Features

Fix: Slider zero-height issue from 2026.05.08.2 has been fixed

The Connectivity Overlay Effects (LCARdS Config Panel → Connectivity tab) bring customizable fullscreen effects that play on disconnection/reconnection with the Home Assistant server.
Choose from a variety of effects such as custom stylized text and HA card(s) - can be scoped by device/user - great for kiosk installs.

The core system behind Connectivity Overlay and the Alert Overlay systems, is now available as an HA Action.

Create your own customized overlays with fully configurable effect layers and cards.
Trigger from automations or card actions - and scope to any device/user.
Useful for simple use-cases where browser_mod is not required.

Two custom LCARdS theme profiles for HA-LCARS have been added.
In Picard style, these coordinate the LCARdS colour palette with the HA-LCARS theme and the core HA colour palette that HA uses to derive other UI colours.
Two accent modes are provided (Red/Blue) and both support Light/Dark mode in Home Assistant.
See Configuration → HA-LCARS Theme Profiles for setup instructions and a full YAML.

Cards now accept max_width and max_height when it is desired to limit card dimensions when autosizing in containers.
Dimension configuration values can now be any CSS length expression: pixels, viewport units, clamp(), calc(), percentages, etc.
This opens up possibilities such as adaptable elbow widths, etc.

Border Hover & Pressed States: Button border colours can now respond to interaction state.
Button Default Label: The default stub label for new Button cards is now a randomly chosen placeholder such as 3E-F2A instead of the static 'LCARdS' string (similar to CB-LCARS auto-generated labels)
New convenience presets panel-light & panel-dark which are preconfigured buttons to be used in decorative mode. They have hover and interactive effects default disabled.

Several Alien fonts have had a size-adjust property adjustment in the @font-face declarations. Improving size equivalency with other fonts. Please report any issues or adjustment suggestions.

Slider: fix autosizing resize loop in dimensionless parent (ie. custom-layout-card)
More documentation updates
CI: add documentation validation for broken links; validation of examples against card schema in the code
several other small fixes an improvements
