# TITLE: 6 CHANNEL LOUNGE DMX MAINS DIMMER
# zorruno.com layout v1.0 2026
#:########################################################################################:#
# VERSIONS:
# V1.1 2025-09-13 Extended to 3 modules and installed
# V1.0 2025-09-06 First Rev (only tested one module, 2 channels at this stage, and incandescent)
#:########################################################################################:#
# HARDWARE:
# - ESP8266 D1 Mini Pro
# - 3 x 2-channel DMX mains dimmer modules (1.2 A per channel)
#   Contoller: https://www.aliexpress.com/item/32838426377.html
# - RS-485 TTL converter (MAX485 style)
#   RS-485 TTL converter: https://www.aliexpress.com/item/1005005737922222.html
#
# MAX485 Module (You could also use a MAX3485 which is 3.3 V)
# - MAX485 VCC  -> ESP +5V
# - MAX485 GND  -> ESP GND
# - MAX485 DE   -> ESP +5V
# - MAX485 RE   -> Pullup so can leave unconnected (or +5V) or a designated enable_pin
# - MAX485 DI   -> ESP GPIO2 (ESP8266) or GPIO5 (ESP32)
# - MAX485 A    -> XLR 3 (DMX +)
# - MAX485 B    -> XLR 2 (DMX -)
# - MAX485 GND  -> XLR 1 (DMX GND)
#:########################################################################################:#
# OPERATION NOTES:
# - ESP8266 transmits DMX512 over UART (one-way TX only) via RS-485 adaptor
# - Dimmer modules must be set to DMX mode and assigned a fixed ID (1-999)
# - Incandescent trial notes:
#   - 10% writes ~26 (max 255)
#   - Very low levels may not visibly output below ~15%
# - Using GPIO2 as UART TX on ESP8266 is handy, as the onboard LED flashes with TX
# - Dimmers are smooth and remember values even if DMX data stops transmitting
# - This design assumes mains power is controlled by a smart wall switch:
#   - If networks fail, toggling power restores the dimmer outputs (and this YAML restores channels to ON)
#
# System Settings on Dimmer: (onboard buttons M and < held for 2 secs)
# - Set "1 Channel" (d-1) and both channels output the same level, or "2 Channel" (d-2)
# - Set reverse phase dimming / trailing edge (C-R) or forward / leading edge (C-F)
# - Set minimum brightness on the dimmer, from b01-b40 (b01 gives ~5% min)
# - Set the 3x 8 segment display to automatically turn off (Bon/BoF)
# - Pull both DE and RE high on the 485 converter to ensure data enabled (or wire enable_pin)

# OFFLINE NOTES:
# - If Home Assistant is offline, lights can still be controlled locally (device continues DMX output)
# - If Wi-Fi is offline, wall switch power-cycling restores dimmer module output state (modules remember)
