WTH, how got my Qingping Clock connected WITHOUT Bluetooth

I suddenly got a message that i could add the Qingping integration to connect my alarm clock. You know, the tiles on the top of the integration page.
I was able to connect the clock and read the temp and humidity sensors.
It all lasted 25 minutes until the sensors went unavailable.

The weird thing is, its a bluetooth clock and my HA is running in docker on a NAS without bluetooth. How is this possible?

I have a zigbee stick connected and an ESP32 mmWave sensor running ESPhome if that matters.

Do you have any Bluetooth proxies?

Not that I know of. What would that be?

Edit: ohhh, just checked my old config for the mmWave sensor and lo and behold, there it is:

bluetooth_proxy:
  active: true

Didn’t even know it was possible to get the sensor data this way. Unfortunatly, the connection lasted just 25min and never came back after this.
