Spike: Determine whether ESP32-S3 RTC feature can be reasonably used #29
Description
Currently, if there's no wifi (and thus no NTP), there's no time for logging purposes.
ESP32-S3 has a built-in RTC feature.
Is this feature usable with the T-HMI board? Can the ESP32-S3 on the T-HMI be powered without poowering other power-draining peripherals on the board?
