Bridge triggers Opener randomly

The Title says it all. The FrontDoor randomly gets a trigger, even I’m not @home.
The LogFile says it gets triggers by the bridge. No Clue why that happens.

Everything went fine since I changed my Batteries in the Opener. Since then it happens and since then I got doubled commands from the BridgeCallBack as well.

Opener and Bridge running on the latest Firmware.
