# Driver has been tested with:
# Gude Expert Power Control 8031()
# HTTP-GET API is defined in the Gude EPC-HTTP-Interface specification:

# The `components=<N>` parameter defines which status information are
# included into the returned JSON.
# * `components=0` happily returns an empty response but still switches the
# outputs as requestd.
# * `components=1` only includes the output's state into the JSON.
