Target SOC being reset to 100%

I've had GivTCP and HA running for maybe 10 days or so and everything seems to work happily - but almost every night it seems to reset the target SOC to 100% at 23:20 each night. Its nothing on the Givenergy side doing it, as the action doesn't appear in the log, and the GE portal doesn't show the change until I go into remote control and re-read the register on the portal.

What am I doing wrong that's making it do this??

Turn off Smart Target in GivTCP. It is enabled by default and will override any target SoC that you set.

Thank you!!
