2026.6.0

What's Changed

🚀 Added

• MQTT: Connect through the Home Assistant API — great for Nabu Casa users or anyone who doesn't want to expose their MQTT broker (#243)
• LWT Sensor: Track when your device goes offline with the new availability sensor (#241)
• Current User: New sensor showing who is currently logged in (#233)
• Update Entities: New button to manually refresh all Home Assistant entities (#236)
• Systemd: Run lnxlink as a user service (#237)
• Bash: New select entity type — expose a dropdown driven by a shell command
• Bash: Set device_class and state_class on custom sensors for better HA integration
• Notifications: Use custom text IDs to update or close notifications by name

🔧 Changed

• Discovery: Old Home Assistant entities are automatically removed when modules change (#245)
• Modules: Failing modules are automatically disabled after 5 consecutive errors so the rest of the system keeps running
• Boot Select: Switched from GRUB to efibootmgr for managing boot entries
• System Updates: apt now correctly filters held-back and phased packages (#234, #235)

🐛 Fixed

• Shutdown / Restart / Suspend: Remote power commands now work correctly when lnxlink runs as a systemd service at boot
• MQTT: lnxlink now exits with a failure code if it can't reach the broker, allowing systemd to restart it automatically (#246)
• Battery: AC adapters no longer appear as 0% battery sensors (#244)
• Mouse: No longer crashes on startup when no display is available yet
• Brightness: Fixed conflict when multiple identical monitors are connected (#232)
• Docker: Update status now shows correctly from the first check instead of after the first interval
• Mounts: No longer crashes on mount points with spaces in the path
• Keep Alive, Notifications, Brightness: Various stability fixes
