Octopus meter readings are different to Fox?

Hi all
I have noticed that Octopus are always different to the Fox Cloud 2.0.
There is not much in it but it is always in their favour. They say I am importing more than what the Fox Cloud says and that I am exporting less than what the Fox Cloud says.
As I say it is not a great amount but it all adds up

The numbers for March are:
Importing
Octopus = 120.296 kWh
Fox Cloud = 114.60 kwh
A difference of 5.7kwh

Exporting
Octopus = 192.348 kWh
Fox Cloud = 191.20 kwh
A difference of 1.15 kwh

A total difference of 6.85kwh

In my case Octopus think I've imported about 3kWh more than Fox think, but they also think I've exported about 3kWh more.

Those are good numbers, a meter is much more accurate than a CT clamp, as the error margin with a ct clamp is +/-10% (or some such value)

Difference
Import is 5%
Export is under 1%
