Over the last few days, I've had several occasions where at 1am the battery starts charging for a short period and then stops again. Battery currently set to not charge overnight, eco mode on and all other settings at default.

@TheDragon (GivEnergy) I'm currently on the beta firmware 3068 that you kindly loaded recently and has resolved the high voltage issue. Could this be a bug in that firmware?

That is a new one indeed.

No one else mentioned this to my recollection.
Is there a serial number I can check at

TheDragon (GivEnergy) thanks it's - ED2151G080

It's not happening every. I have been playing around with Flux export from the battery using the Octopus R&D scheduler - however I'm having to reset to defaults via the web portal after the export period otherwise the battery stays at idle. So each night before this has happened the system has been set back to default to with eco on and no timed charge.

Rubikcube It does indeed. The common thing I can see here is that I have been playing around with Octopus R&D for flux export at peak times, but I do need to set everything back to default after.

I happened to be checking the GE app early this morning when a spike on the grid occurred.

Charge Mode set to - Solar only, yet during the 1 minute before the Solar + Grid finish time the battery went idle and all the consumption for that 1 minute was from grid.

Solar + Grid finish time = 0520, though should not be in use as mode set to Solar only.
From 0518 to 0519, the battery was idle/paused, so all consumption from grid.
I happened to be running a boost on my Eddi for the immersion heater, along with a trickle in to the car, approx 1.4 kW each so with a little feeding the house the total power from grid was 3.0 kW for the 1 minute.

The web portal only captures a snapshot every 5 minutes, so there is no evidence of this occurance on the power graph.

TheDragon (GivEnergy) this has started happening again since I have started charging the battery from the grid overnight in the last week. Always at 0100. I'm not using any automations.

And again last night
