False ring detected?

This is a followup on my other thread with a different probem: Node-RED: Detect Ring via Node-RED (Opener and Bridge) - #2 by xanathon

I just got a ring event via http:

deviceType: 2
nukiId: xxxxxxxxx
mode: 2
state: 1
stateName: "online"
batteryCritical: false
ringactionTimestamp: "2022-12-20T10:01:59+00:00"
ringactionState: true

But nobody rang. What happened? I test for “ringactionState: true” to trigger further action. Is that wrong? But why was there a ring event anyway if nobody rang?

Support said I have to ask for help in the forums. In the forums I am ignored completely. Looks like Nuki is begging for bad press.
