dsmr_reader_custom_config

# Custom config for Marcel Zuidwijk his DSMR reader. 
# used wifi secrets tomatch my config and secrets for API OTA passwords (added)
# using different names (from official docs) and kW(h) for everything (not Watt)
# added sum sensors to calc low and high tarif into 1 sensor per consumed / returend.
# added throtteling for some less important metrics like voltage and per phase prod (not total) to 10s instead of 1s updates.
