Does anyone know why this happened? At midnight my battery began a charge from 20% up to 100%. I have Eco set on and the timed charge was set for 3.30 until 4 am only? It has been working normally before.

Unexpected charge to 100%
I was just about write a thread on this issue also....i have set mine a number of times to either only charge to say 20% in a timed period (on both the phone app and the pc) or not to time charge at all.
It seems to work maybe for one night then resets to 100%.
Its getting really frustrating!!
Have you got a tariff card showing on your web portal homepage?
If so, is the automation part of that card enabled?
The tariff automations generally charge to 100%
So if you want customisation, disable that automation.
I did, thank you, I have submitted to stop automation now. Hopefully that works, I hadn't noticed that before!
RichardBarton using GivTCP at all? There's a smart target setting that can be disabled - it aims for 100% during the winter months and lower percentages the rest of the year. Might not be relevant now we are in March (can't remember exactly what months it uses 100% as the target).
TX200 no, I don't use Givtcp. It's a wierd situation. It worked fine the day before. Usually i change the charge amount and time each evening as I'm on Octopus Agile.
I'll reset everything to default then put my charge % in again as see what happens tonight.
The only thing to note was that last night, it took several attempts before the settings were accepted. Prior to that I kept getting an error.
I had a look at yesterday's profile and it seems I had a period of unplanned export and then the battery hit the low stop and went through what looks like a calibration cycle
