Does anyone have a situation with their reported Powerwall grid consumption being more than an order of magnitude out against what their smart meter records?
In my case the Powerwall app reports grid usage/import of 0.2 kWh from the grid for a day. However my smart meter reported usage of 4.063kWh for the same day.
Looking at my smart meter readings the figures are measured down three decimal places whereas the Powerwall app records figures to one decimal place. I have spoken with Tesla who have advised that there is no issue with my Powerwall and my energy supplier who could not find any issues with the smart meter.
When I look over the course of the day the majority of half hourly readings from my smart meter are below 0.09 kWh so I assume the Powerwall is unable to measure that?
