Maybe it is limitation on oreo? Try to make sure Automagic is whitelisted from privacy guard (settings > security > trust). If there is setting to block sensor wakeup, try to disable that too.

Thanks for the advice. I whitelisted automagic, but the problem still presist. What is interesting is that first screen off BLE detection seems to be alright the next detections are not going through though. It's really hard to debug something while your screen has to be off. I did not find any sensor wake up blockers.

It can be your flow design? Try to change the trigger to periodic timer with 5 or 10 seconds and switch the screen off. Give a vibrate action, parallel to the ble check, to make sure the flow is running.
