WDT not fires

[executer-uno]

Very rare times board stops to response. I made small investigation on my own branch version of SW - it stucks somewhere inside SDK client function calls and no WDT fires occurs. I thought about external watchdog IC, but after found proper google request I found that solution:
esp8266/Arduino#1532
It not tested by years, but looks fine and extra WDT should not be a problem. I just want to advice it to implement.
Thanks for your project!
PS: Also ESP8622 not supports WDT period customization, Im not sure about ESP32. But you trying to define it in the code, it can confuse someone)

A WDT is never a real solution. It is always a workaround which might help in special cases, but hide more severe problems which don't get detected for a long time.

Can you please provide more information?

• Did you compile the firmware yourself?
  • If yes, did you use the Arduino IDE or VisualStudio Code?
• Which firmware version do you use?
• How is your configuration?
  • Which sensors, APIs and LCDs do you have enabled (the easiest way is to save the config and copy the resulting web-page as text)?
• Which language of the firmware do you use?
