MQTT Home Assistant Integration Plan	Detailed plan for adding MQTT discovery-based Home Assistant integration to the split-flap display Flask app	project

Plan to add MQTT integration to the split-flap display so Home Assistant can control it natively.

Why: The display is currently only controllable via the Flask web UI. MQTT lets HA send text, switch apps/animations, and see current state via auto-discovered entities.

How to apply: When implementing, all changes go in SplitFlap-RPI-FRONTEND/frontend_code_apr24/app.py. The full plan is saved at .claude/plans/cached-beaming-twilight.md.

Summary of approach:

Add paho-mqtt dependency
MQTT settings added to load_settings() defaults: broker (homeassistant.local), port (1883), user, password, enabled flag
3 HA entities via MQTT Discovery: text (send display text), select (switch app/animation mode), sensor (current display string)
All entities grouped under one device, shared LWT availability on splitflap/availability
Command handlers reuse existing patterns: send_to_display(), active_app, stop_event.set(), loop_delay logic
State published with retain=True from send_to_display() and route handlers so HA stays in sync
Graceful fallback if MQTT unavailable (same pattern as serial fallback)
Firmware and serial protocol unchanged
Broker: Mosquitto add-on on Home Assistant
