You can buy energy monitors which either use a clamp sensor round one of

appear to give instantaneous readings and daily totals.

Does anyone know of anything more granular - preferable with the ability
to capture the data and insert it into a spreadsheet? Sounds maybe like
a Raspberry Pi application?

does it on a Pi, and will sell you the parts need to hook up to your meter
for not-very-much.


Looks interesting, but (so far as I can see) only works for electricity
metering, not gas.

Given that I don't have a power socket next to the meter, and I've
already got several Pis running, would it be feasible to get the sensor
head, and use the wireless to talk to an existing Pi ? (the site
suggests it might be)
