# Output from above:
#G daymean HH:MM 12:20 n 1 flow|W 181.51 SoC|% 69
#G daymean HH:MM 12:25 n 1 flow|W 102.94 SoC|% 70
#G daymean HH:MM 12:30 n 1 flow|W 109.51 SoC|% 72

# Note that consumption.net.wNow is import, so is negated.

# Maybe run as:
# Prepare graph with a command similar to:
#sh $0 < /var/log/Enphase/XXXXXXXX.log > .work/tmp/batsim1-daymean.dat.tmp && gnuplot graphing/storesim/batsim1-daymean-1.txt
# eg:
#sh script/EnphaseBasic-to-batsim1-daymean.sh < /var/log/Enphase/20180809.log > .work/tmp/batsim1-daymean.dat.tmp && gnuplot -e "title='Outturn 2018/08/09'" graphing/storesim/batsim1-daymean-1.txt && chmod a+r batsim1-daymean.png
