ESPHome blinds with a stepper motor

blinds.yaml

# ESPHome config to control veneitan style blinds where a stepper motor has been attached to the spinning rod that lits the blinds one direction or other.
# 3D printed model by sidoh:
# https://www.printables.com/model/22186-retrofitted-motor-mount-for-blinds-automation
# Cobble a bunch of code from the designer's config:
# https://github.com/sidoh/esphome/tree/master
# This is setup to use a ULN2003 driver. Also a bit of modification because saving the end_posotion
# value didn't make sense.
#
# If it's not clear, this device is setup with 2 steppers for 2 different sets of blinds, left and right
# Please pay attention to which direction your stepper motor is turning during the intial config
# so you don't accidentally snap any wires.
#
# To configure start and stop position first begin by setting the blinds to the close posotion.
# You can do this by calling the HA servce control_stepper. You can use negative values. For my
# steppers 2048 steps is a full turn. Once at the closed position
# call the service set_closed_position to set the current step value to zero/origin.
# Use control_stepper again to get the blinds to what you would like to be as an option position.
# You can again use nagtive values if needed.
# Now use set_open_position to save to memory the numbers of steps from 0 to be decalred as fully open.
# And that should be it. Values will get saved to flash and should be restored on restart.
