I know exactly what my daily consumption is summer and winter. All
done with a biro.

I was doing that and feeding the data into a spreadsheet once per week,
but it really didn't compare to the 30 minute samples I get now, nor
the instantaineous consumption readings via the remote display.

1 minute logging interval for consuption, 5 mins for voltage here.
"Real time" display of consumption. Web based plots of both
available. Not a smart meter in sight or letting a third party have
the data either.

CuurentCost consumption monitor for power, UPS for voltage, via the
server running linux. A Raspberry Pi could do all of it without
breaking into a sweat.
