# Credit where due....
# I put a certain amount of work into this, but a lot of ESPHome integration is
# "look for other examples and see what they do" programming-by-example. Here are
# things that helped me along with this:
#
# - I mined the existing tsl2561 integration for basic structural framing for both
# the code and documentation.
#
# - I looked at the existing bme280 integration as an example of a single device
# with multiple sensors.
#
# - Comments and code in this thread got me going with the Adafruit TSL2591 library
# and prompted my desired to have tsl2591 as a standard component instead of a
# custom/external component.
#
# - And, of course, the handy and available Adafruit TSL2591 library was very
# helpful in understanding what the device is actually talking about.
#
# Here is the project that started me down the TSL2591 device trail in the first
# place: https://hackaday.io/project/176690-the-water-watcher
