- Flatten DisplayController: remove _set() middle layer
- Inline on_ring() into _handle_protect_event (was a 2-line wrapper)
- Collapse triggered flag in touch monitor to single boolean expression
Remove vcgencmd display backend, simplify DisplayController2026-04-13T12:45:07+00:00Luke Hoerstenluke@hoersten.org2026-04-13T12:45:07+00:00urn:sha1:c1bd1d0f3abe8d4de65f2c95731711a6efa3008d
Always use sysfs backlight. vcgencmd resets DRM planes under fkms
making it incompatible with the drm video output. Removes
libraspberrypi-bin dependency and panel/vcgencmd dead code.
Remove warm prebuffer mode from doorbell-viewport2026-04-13T12:37:42+00:00Luke Hoerstenluke@hoersten.org2026-04-13T12:37:42+00:00urn:sha1:8a14be01daaa8c77733e53ed1da2a6914aaac407
Always start mpv on demand (cold start). The warm path was fragile on
the RPi4 with fkms and added complexity without reliable benefit.
Switch doorbell-viewport to cold start, add backlight diagnostics2026-04-12T19:10:34+00:00Luke Hoerstenluke@hoersten.org2026-04-12T19:10:34+00:00urn:sha1:63bc6c512cd64dac27a4f34b6c1342bee39c00d5
- prebuffer_mode=cold: mpv starts on demand at ring/touch event
- Add tty group to service user for DRM TTY access
- Log backlight brightness changes for diagnostics
- Remove --really-quiet suppression during debug (now restored)
Fix doorbell-viewport display and ring detection2026-04-12T18:48:06+00:00Luke Hoerstenluke@hoersten.org2026-04-12T18:48:06+00:00urn:sha1:9f8fa6bd4af9dc3b56efcf5de8c175d41b60923d
- Switch to sysfs backlight (drm backend) to avoid DRM plane reset on
display power cycle caused by vcgencmd display_power
- Add udev rule and sysfs permissions for rpi_backlight
- Fix multi-packet WebSocket decoder (ring events were being dropped)
- Fix mpv loop/cache flags (--loop=no, bounded --demuxer-max-bytes)
- Remove hardware decode (caused SIGSEGV on RPi4 with fkms)
Fix doorbell-viewport bringup issues2026-04-12T18:13:16+00:00Luke Hoerstenluke@hoersten.org2026-04-12T18:13:16+00:00urn:sha1:1298d68bb9bc33b84a70e4c9c27c806d8a0748c9
- Fix websockets headers kwarg via inspect (works across all versions)
- Use full path /usr/bin/vcgencmd; add libraspberrypi-bin dependency
- Fix UniFi Protect WS packet decoder to handle multiple concatenated
packets per message (action+data in single frame)
- Fetch lastUpdateId from bootstrap for WS URL
- Switch fbcon disable from video=HDMI-A-1:D to fbcon=map:99 (fkms compat)
- Default drm_connector to DSI-1 for fkms; drop hardcoded drm_mode
- Add --no-audio and --hwdec=no to mpv; fix DRM mode-setting race on startup
- Add PoE HAT fan control with configurable temp thresholds
Add doorbell-viewport role2026-04-12T16:52:58+00:00Luke Hoerstenluke@hoersten.org2026-04-12T16:52:58+00:00urn:sha1:c528cf7268463c84a050129665ce08814fd1d420
RPi4 portrait touchscreen that shows a live UniFi Protect RTSP stream
on doorbell ring or touch, with display fully off at idle. Supports
warm prebuffer, vcgencmd/drm/panel display backends, evdev touch input,
and configurable DRM device/connector/mode.
