I having QBKG12LM with power on, the mqtt spamming power change every second.

This is due to fluctuating power.

I tried using debounce: 300 to suppress the notification but it is giving issue.
Whenever I turn the switch on, the switch physically turn on correctly but the mqtt publish “OFF”

‘0x00158d00023b2823’:
friendly_name: switch_kitchen1
debounce: 300
debounce_ignore:
- state_left
- state_right

Futher troubleshooting found this line of code publish the OLD state immediately when old and new state different. I am dont understand why …

File receiver.js.

line 31

   if (this.isPayloadConflicted(payload, this.debouncers[ieeeAddr].payload, debounceIgnore)) {
        // publish previous payload immediately
        this.debouncers[ieeeAddr].publish.flush();
    }

I have no idea what does this line do… I commented it out and it work flawlessly.
