CT accuracy

Is there anything that would affect the accuracy of the CT?

I happened to compare the total consumption on the VRM portal with my smart meter. Typical daily total grid consumption at the moment on VRM 0.3KWh per day v’s 1.1 KWh per day on the Smart meter. (yes very low consumption, ESS and solar working nicely) Whilst not overly bothered by the 800Wh the inaccuracy of 366% does.

I assume the consumption total in VRM is derived from the CT Sensor?

Not knowing your system setup - have a look here

Some of it is calculated and thus may show differences.
