# This file is a package and should be located in the config/packages
# folder. If you do not have a packages folder then create it and add
# the following to configuration.yaml
#
# homeassistant:
#  packages: !include_dir_named packages

# More information on packages can be found at https://www.home-assistant.io/docs/configuration/packages
#
# Set up some observation sensors.
# This uses the Home-Assistant-wundergroundpws https://github.com/cytech/Home-Assistant-wundergroundpws integration.
# Rain information (wupws_preciptotal) is a daily accumulation total. So we want to grab the
# data just before midnight to get the daily total. We shouldn't be too eager to look after midnight
# because the reset from WU may take a few minutes to come through, currently 10 min. Increase this
# if data is unreliable.
# Note: Requires the ha-average integration to be installed https://github.com/Limych/ha-average
