# Title: BREAKFAST BAR LEDS (Lounge)
# Repo: https://home.fox.co.nz/gitea/zorruno/zorruno-homeassistant/src/branch/master/esphome/esp-loungebookshelfleds.yaml
#
# v2.0 - 2025-09-15 A bunch of fixes and made it more standard across my devices
# v1.0 - 2025-08-17 First setup (and replacement of Tasmota)
#
# ------------------------------------------
# OPERATION (as of v2.0)
# ------------------------------------------
# 1. General-purpose LED controller.
# 2. Designed for the Sinilink XY-WFMS board with a MOSFET output (claimed 5A, 5-36 V DC), but will suit similar mosfet boards.
# 3. (In SUBSTITUTIONS) setting for MAX % output to extend LED life (ie can ensure it is only ever 95%)
# 4. (In SUBSTITUTIONS) Minimum output setting; switches fully OFF at/below the minimum to avoid low-PWM flicker.
# 5. (In SUBSTITUTIONS) PWM frequency is set to 1kHz by default. You can increase it, but higher values caused
# resets on Sinilink device. On ESP32 you can run much higher (~40 kHz).
# 6. Min/Max output settings are not exposed in Home Assistant/MQTT by default, but could be.
# With a 1 MB flash, space is tight and only minimal optimisation has been done so far.
# 7. (PACKAGES) include common items: network settings, diagnostic entities, MQTT, and SNTP (optional).
# 8. Default behaviours, for recovery from lost power or reset:
# - "Fade up to full": fade from floor to max on boot.
# - "Restore Brightness": fade from floor to the last brightness on boot (should be no on/off blip/flash).
# - "Remain Off": stays off on boot.
# 9. The green LED flashes while fading (different patterns for up/down). The red LED follows the
# output (it shares the MOSFET GPIO). (Obviously this depends on hardware)
# 10. Fade timing scales with the configured values (proportionally when starting mid-brightness).
# 11. Exposed in Home Assistant/MQTT:
# - Startup action (On,Off,Restore)
# - Fade Up / Fade Down / Fade Stop buttons
# - Fade Up/Down toggle switch (keeps fading up to full, or down to off unless stopped)
# - Normal On/Off switch (quick ramp up/down, up to the level of previous brightness)
# - Fade up/down times (0-60s)
# - Output % (pre-gamma) and PWM % (post-gamma)
# - Output Set (1-100, respects min/max). This also changes with other output so reflects value.
# - Many device diagnostics (from the included 'diagnostics' package)
# - Maximum 'on' time before automatic fade-down (1-48 h, 0 = no limit)
