Returns the hardware RTC type (DS3231, RV3028, PCF8563, RX8130CE)
or 'internal' when no external module was detected, alongside the
current date and time in UTC. Useful for verifying that an external
RTC is active and providing correct time to the node.
AutoDiscoverRTCClock now syncs the fallback system clock from the
hardware RTC immediately after discovery in begin(), and re-syncs
every hour via tick() to correct drift. Invalid RTC readings (before
2024-01-01) are ignored to handle unpowered DS3231 gracefully.
Support for R1 Neo hardware. New variant and baseboard class.
* Known issues:
- power management is not currently supported
- power off via long button press is not implemented
