Soft WDT reset in HomeAssistant-MQTT
Hi, on a serial console I am observing soft WDT reset periodically, there are some articles in the net about it, eg. https://github.com/esp8266/Arduino/issues/2866 which suggests issues with watchdog timer, but I don't know how to identify relevant code line for this. Any hints?
