In the new Amazon FreeRTOS firmware (devices with shadow schema 0.3 and above), you can access detailed debugging information related to device resets. This information helps engineers understand why a device has rebooted or reset, and how often it has happened.
Note: These counts track resets over the device’s runtime since the last major reset, not since manufacturing.
The ESP soft reset reason shows the last recorded soft reset cause along with the total count for each type, provided in a mini JSON payload for easy debugging.
