I wrote the new firmware with updated sdkconfig at about 3pm yesterday and it rebooted and lost the state of charge metric at 8:45pm, the car woke up at midnight and started charging, providing data for the SOC metric, during the charge there were a couple of gaps in the telemetry, charging finished at 3:10am and the OVMS rebooted at 3:45. The OVMS then stopped sending telemetry completely at 7:20 am when the car was switched back on.
