Evaluate LineageOS camera support for an Echo Show Home Assistant kiosk

[CCOSTAN]

Summary

Evaluate whether the recent LineageOS Echo Show camera work can improve the Home Assistant kiosk setup.

Reference

• Reddit discussion: https://www.reddit.com/r/homeassistant/comments/1vbvg3a/for_those_using_an_echo_show_5_with_lineageos_i/
• Camera support project referenced there: https://github.com/jxlarrea/lineageos-echo-show-camera

What to investigate

• Confirm the exact Echo Show hardware generation used by the target kiosk device.
• Determine whether the LineageOS camera patches support that generation; the referenced work was tested on Echo Show 5 (2nd Gen), while 1st Gen hardware uses a different sensor.
• Assess whether the camera can expose useful Joanna functionality such as live preview, still captures, snapshots, or presence/motion workflows.
• Compare the effort and risk of applying the LineageOS/build-and-ADB workflow against the existing kiosk setup.
• Identify recovery, backup, privacy, and rollback requirements before any device changes.

Acceptance criteria

• Hardware compatibility and generation requirements are documented.
• The proposed integration path and prerequisites are documented.
• Privacy and recovery risks are called out.
• A clear recommendation is recorded: proceed with a test, defer, or close as not applicable.
• No live device or operating-system changes are made as part of this tracking issue.
