Reset Reason "RTC Watch Dog Reset Digital Core And RTC Module" on esp32s nodemcu (2)

ESPHome
1

Hi, I’ve gotten a power monitor setup using CircuitSetup Expandable 6 Channel ESP32 Energy Meter and esp32s nodemcu (aliexpress link). About every 12hrs I see that the ESP32 has reset and the reset reason is “RTC Watch Dog Reset Digital Core And RTC Module”. It is also happening at around 4am and 4pm every day. Below is my configuration and I have searched online on various sites for any similar cases but couldn’t find any. The version of ESPHome I’m using is 2023.2.4.

Recently the esp32 has reset after 24hrs, ie at 4am today with the same reset reason.

As an update right now, it seems to be hanging bad enough for it not to be reachable from the network, I doubt the wifi is not reaching enough, so I guess I’m in one of those cases were I need to do more debugging cause of a more serious problem. Would appreciate if someone could recommend me a serial to sd card solution, that is because I want to save everything coming out of the serial to an sdcard and be able to view it later on after the issue randomly happened on the esp32. I think the openlog solutions from sparkfun are good options, but still looking around.

Did you find out the cause for constant watchdog resets?
