IKEA Tradfri ON/OFF switch triggers after rebbot

Good day, I am using ioBroker and an IKEA switch as a remote to open/close my garage door. So far all worked perfectly well. However, tonight we had a power outage causing the phoscon to reboot. (ioBroker is powered by UPS) After the reboot, the garage door opened, and remained open over night :frowning: . Obviously the switch somehow changed status during reboot. The script is triggering the door actuator on “buttonevent 1002” solely, so no other root cause possible.
As a workaround now I am checking if the garage door is open during “critical daytimes” and if so, it will be closed. I will not invest lots of hours to troubleshoot, I’ll rather get another switch (non IKEA). Any recommendation?
However befor trashing the switch I’d like to ask you guys if this switch’s behaviour is normal ?
