I have had my Konnected Alarm Panel Interface kit for over 2 years, working perfectly. In the last month the buzzer stopped working. The only thing that changed was HomeAssistant software via their upgrades. The Buzzer button on HA looks different now too, it has lighting bolts symbols instead of being a toggle switch.
Any one have any idea how to fix that? I rebooted everything several times still doesn’t work
EDIT: I just went to HA, clicked on the lighting bolt , and it turned into a Toggle switch and the buzzer works now. If it changes back to lightening bolt I will come back
Now it stopped again. When I click the Toggle buzzer button on HA I get: Failed to perform the action switch/turn_off. unknown error. No idea what to do next.
It work perfectly for years.
All the other sensors, work fine. Windows, Doors, Presence, all fine, just this piezo that doesn’t work
I guess this explains it:
This stops working in version 2026.4.0. Please addreKonnected upgrading.
