Some events are missed?

Since a week or so ago I’ve noticed that a few events (motion) from my Fibaro motions sensors are being missed.
I’m keeping an eye on the HA log and see when automations trigger, I haven’t begun analyzing the OZW log yet as I have a bunch wall plugs that fill that log with reports so it’s harder to get a good overview on.

Has anyone else experienced this behaviour?
(it can’t be range dependent, the sensors are within 5m from the bridge)
