# Example register definition file. 
# Device is a Eastron SDM630 power meter. Register specification e.g.
# available at http://www.ausboard.net.au/index_files/Eastron/Eastron%20Modbus%20Registers.pdf

# All those defaults are set with a magic "DEFAULT" topic definition and
# are then inherited by subsequent register definitions.
