# Butterfly EDFA Rack — snippet to merge into Home Assistant's configuration.yaml.
# These are top-level keys; add them alongside your existing config (the rack's
# sensors/switches/numbers come in automatically over MQTT discovery, so only
# the derived mW power sensors and the dashboard registration live here).
#
# The internal PDs read ~0.5 dB optimistic, so the mW figures are indicative.
