Soft WDT reset in HomeAssistant-MQTT

[witek1308]

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

update
in tests I identified moment when it happens - each time when I try to send 1A over MQTT

I used to face similar WDT behavior due to poor power supply.
Some noisey power source might call reboot

I powered it from usb during serial monitoring. In addition it was stable all the time for any read, until I tried to send 1A over MQTT (to arm). Not sure in my case it would be power supply but will maybe try something else

Hi @witek1308 - I haven't run into the WDT issues, if you're still running into this with the current esp8266 Arduino Core 2.5.1 please post a new issue and let's take a look. Thanks!
