Default state is overridden from switch device

[ymoona]

I have an ESP configured to make to make a pin high on boot.

Hardware tab:
Pin mode 12 (D6): Output High

This works fine on boot.
But I would also like to control and report on this pin using MQTT.

Controlling works by enabling the OpenHAB MQTT controller and publishing messages.
But in order to receive state on the switching of the pin (confirmation that the pin is indeed switched) I have configured a switch on the same pin.

Devices tab:
Switch input - Switch led2 ❶ GPIO-12 state: 0

At runtime this works fine, I can send MQTT messages and I receive back state.
But at boot something happens that I cannot explain.

Boot Sequence:
Led is turned on
After about 5 seconds the led is turned off

Bootlog:
6392 : Subscribed to: /ESP_TEST/#
6414 : EVENT: System#Boot
6546 : SW : Switch state 1 Output value 1
6578 : EVENT: led#state=1.00
6758 : SW : Switch state 1 Output value 1
6780 : EVENT: led2#state=1.00

I have also a rule enabled to set output to high on boot.

When I disable the device the pin stays high after boot, but then I dont get feedback on MQTT.

What am I missing here?

Is mqtt retain flag set under advanced tab?

No it is not

And issue also occurs when the controller is disabled.

Try to disable the pull-up resistor for the input switch device.
