Upgrade ArduinoHA from 1.3.0 to 2.1.0 and rewrite mqtt.ino for it. The clock now shows up in Home Assistant (discovery prefix "homeassistant") with: - switches Tubes (blank the display, runtime only) and Auto dim - numbers Day/Night brightness - light Backlight (on/off, brightness, RGB mapped to the colour wheel) - select LED effect, button Cathode protect - sensors Light (LDR) and WiFi signal, plus the upstream sensors when the clock has them; master-clock subscriptions are kept Settings changed from HA are saved to EEPROM 3 s after the last change. Fixes the unbounded memcpy in the MQTT message handler. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
