I should have said the supply was off after the meter. I've noticed this before when nothing is connected to it.
When I have forced myself offgrid and switch off the grid isolator I definitely get zero to three decimal places on my smart meter history, i.e. 0.000
Maybe a rounding error from the previous half hour ?

Surely it must be using power to report what is or isn't being used. 1 watt every 3 or 4 hours...

This is how it looks when nothing at all connected, so shouldn't be any rounding errors..
My readings show 0.02kwh all the time I am off grid, when I get home in a few weeks I'm actually going to switch off the power from the meter to my inverter and see if it still reads something.

To be done, more panels and a wind turbine

Yes, but that power is taken from the unmetered side, directly from the incomer, before the current shunt in the meter, so doesn't get measured or recorded by the meter.
25 off 250W Perlight solar panels, installed 2014, with a 6kW PowerOne inverter, about 6,000kWh/year generated
6 off Pylontech US3000C batteries, with a Sofar ME3000SP inverter

Yes it says somewhere in the smart meter specs that the power to run the smart meter does not get added to the customers consumption.

Octopus seem to be taking their time producing results.
I wish they'd hurry up; I'd like to see if I have achieved any saving this time rather than my miserable failure to do so last time.
