# All kamstrup meters are read in a single sequential burst (determined by READ_RATE)
# Generate same time stamp for all meters read in one sequential burst
# Drawback: if you have multiple devices, timestamp might deviate a bit from actual time measurement is done
# Advantage: all measurements in one sequence will get same timestamp for influxdb
# Reading burst for the 2 power meters used in this example takes about 2 seconds
# Timestamp is with 1sec accuracy; if you need more, adapt code a bit
