#----------------------------------------------------------
# TO DO:
#
# TUYA WOOD PELLET STOVE Converted to ESP32
# version 4.0
# Added PID controller to iding mode that changes auger OFF time dynamically
# Start w/ these values: desired_pipe_temp=150, PB = 15, Td=75 , Ti=50, stoking temp == 131F
# version; 3.1
# date 12/28/24
# Add routines to shut of Auger every time it shouldn't be on.
# date: 03-21-23 bug fixes
# version; 3.0.1
# date: 03-21-23 bug fixes
# 3.0 converted to ESP32, added realtime exhaust sensor
# 2.0 added fire stoking function
# 1.0.0 added a Power Level P5 (ultra low power) that is fully configurable while in ECO2 mode.
# 1.1.0 added echo of actual display messages and status via Display's MCU UART monitoring
#
# All of these mods give a new "Ultra Low" power level which turns down the heat during IDLE mode so the stove goes thru fewer (no)
# on/off/igniter cycles and just maintains a lower heat output (for smaller rooms)
# when the room cools enuf, ECO2 mode will kick back to "Heating" which
# turns off this new Ultra Low power level, then once the room temp is +2F above set temp, stove
# goes into "Idle" mode again and new Ultra Low is active again. The cycle repeats and the stove stays lit.
# and room doesn't drastically heat up driving your wife nuts.
# These mods ***require*** replacing the Tuya chip with an ESP32 D1 Mini & some MCU control board and Display board mods.
# See Github Discussions for complete details
#
# NOTE: I am NOT a career/pro programmer. There is probably tons of opportunity to
# consolidate many of the if/then statements that check things into convoluted programmer-porn style
# Lambda evaluations, but I hate writing and debugging Lambdas,
# so my code makes way more sense for the average person and is very easy to debug.
# Your mileage may vary.
# And, more inportant, it gets the job done!
#----------------------------------------
# GPIO16 <- TX PIN ON DISPLAY BOARD
# GPIO21 -> RX PIN " " "

# GPIO25 - > AUGER OUT TO OPTOISOLATOR
# GPIO19 -> LED ON DISPLAY FOR P5
# GPIO26 -> THUMBS UP RESET
