# Title: BREAKFAST BAR LEDS (Lounge)
# Hardware: Magichome inline single channel dimmer (ESP8266)
#
# Repo:
#
# v1.0 - 2025-08-17 First setup (and replacement of Tasmota)
#
# ------------------------------------------
# DEVICE GPIO (Magichome ESP8266)
# ------------------------------------------
# GPIO02 Blue LED (used for ESPHome status) - I think... can't see the board
# GPIO12 MOSFET output (0 V when switched)
# GPIO13 Green LED (used to display fading status)
#
# ------------------------------------------
# OPERATION
# ------------------------------------------
# - Startup/power restore action
# - Fade Up / Fade Down / Fade Stop buttons
# - Fade Up/Down switch
# - Normal On/Off switch (quick ramp up/down)
# - Fade up/down times (0-60s)
# - Output % (pre-gamma) and PWM % (post-gamma)
# - Output Set (1-100, respects min/max)
# - Device diagnostics (from the included package)
# - Maximum 'on' time before automatic fade-down (1-48 h, 0 = no limit)

# - Fade up/down times (0-60s)
# - Output % (pre-gamma) and PWM % (post-gamma)
# - Output Set (1-100, respects min/max)
# - Device diagnostics (from the included package)

# Moes Mains Dimmer
# Mains dimmer 150W single channel - Moes Wi-Fi Dimmer Module
# Module swapped to a ESP-02S module (from a Tuya WB2S)
#
# V1.0 2025-09-05 First Rev
##########################################################################################
#
# NOTES RE TUYA COMMS FOR THIS MODULE
# - Toggle DP1 (switch) to 1/0 for ON/OFF — the dimmer’s MCU does the smooth ramp itself over a few seconds.
# - We set DP2 (brightness) on a 0–1000 scale; this is the actual brightness level your firmware uses.
# - We read DP2 back as a sensor (and also show a % view) so we can see the live target the MCU is using.
# - DP3 is exposed only as an optional minimum-brightness limit; not touched during normal dimming unless you tune the low end.
# - It appears that 11 is the lowest DP3 raw value. Brightness of 1% sets this, and 2% ramps it to 19.
# - 50% brightness is 501, so it is pretty linear (you can't set Gamma, see below - I guess you could script it though)
# - DP4 (mode) exists but left alone (unless you want to experiment with load type/behavior). I can't see it do anything. Disabled by default in HA.
# - gamma_correct supposedly remaps the HA slider (no Tuya traffic) BUT it must be set to 1 or weird behaviour (keeps ramping to 0)
# - setting logs to DEBUG will show what is happening with Tuya commands
