0.3.0-beta.1

What's new in 0.3.0-beta.1

Added

• Combined groups — select two or more existing groups and get a unified set of sensors that aggregate data across all of them
• Combined group sensors: offline count, offline entities list, low battery list, low battery count
• Binary sensor any_offline — turns ON when any entity in any included group is offline
• Card: combined groups now supported — card auto-detects group type and adapts its layout
• Card: combined group view shows per-group breakdown table (online / offline / low battery per group)
• Card editor: Group Slug field replaced with a dropdown populated from discovered groups; regular and combined groups shown in separate optgroups
• Card editor: controls that don't apply to combined groups (availability bars, filters, sort, entity detail, suppress buttons, color thresholds) are hidden automatically when a combined group is selected

Fixed

• Automations no longer fire on HA restart for devices that were already offline before the restart
• Random false-positive triggers during HA startup (devices briefly appearing offline while HA loads) are now suppressed for the first 60 seconds after startup
• Suppress/unsuppress services are no longer unloaded while a combined group entry is still loaded
