As per the title, recently, when I look at the power graph, the battery % suddenly goes from 100% to 4% for no reason, i.e. there's no power being taken from the battery. A short while later it returns to 100%, again for no discernible reason. Any clue what is going on here?
Thank you.

I should have added that I am enrolled in Octopus' Charge Pack initiative. Is there some kind of interaction with their remote control of the inverter causing false readings perhaps?

tkearsley I'd guess it's just a spurious reading. Unless it coincides with grid import to cover house load ?

DD I'm pretty sure it must be spurious. When a switch from 100% to 4% or vice-versa occurs there's no discernible input or output from or to the grid. I've only noticed it since Octopus took over control of the battery so I reckon there's some interaction going on.

tkearsley Hmm - yes, perhaps it's two clients to read data at the same time ?
