# This script connects to the Telsa Powerwall 2 gateway API and shows
# the real-time electron between the solar panels, Powerwall, grid,
# and the house (load).
#
# This script uses the API instead of the querying the database to
# reduce the load on the database.  This script is set to update
# every 1 second or as defined in the time.sleep function.
