Home Assistant - Alarm Panel Pro Piezo output (OUT1/OUT2) won't turn off

Hi everyone,

I’m having an issue with my Alarm Panel Pro integrated with Home Assistant.

When I connect my piezo buzzer to the dedicated outputs (OUT1/GND or OUT2/GND on the side edge of the board), the buzzer starts sounding immediately and stays on constantly.

I have tried configuring the zone in the app as:

  • Switch

  • Momentary Button

  • Multi-output

Regardless of the configuration or the ON/OFF state in Home Assistant, the buzzer continues to sound without stopping. I have already tried switching between OUT1 and OUT2, but the behavior is the same.

Am I missing something in the configuration? Is there a specific setting to invert the output logic or a jumper I should check?

Thanks in advance for your help!
