Oh FFS - house storage battery decided to do a full charge for maintenance.
In the middle of peak electricity cost time 🤦🏻‍♂️

Thanks #Sonnen. Thonnen. #homeautomation

@matstace How much is that anyway, 2 kWh?🙃
@skolima The battery was at around 50% at the time, so 5kW. Cost me about £1.90, and would have cost about 80p at off-peak.
@skolima So, you know, really breaking the bank there ;-)
