cloudline-exhaust-3-led.yaml

# This configuration allows a Shelly-RGBW2 to contol an AC Infinity Cloudline
# exhaust fan.
#
# This version of the config supports a pushbutton to cycle through fan speeds,
# and expects you to use 3 separate LEDs as a status indicator, which will light
# individually 1-2-3 based on the fan speed.
#
# For the most up to date version of this config, see:
# https://github.com/ex-nerd/esphome-shelly-cloudline
#
# For details about Shelly, see: https://devices.esphome.io/devices/Shelly-RGBW2
