EnOcean strange behaviour: IPS status not updated (ReturnID incorrect)


There is something weird going on with my EnOcean devices. All of a sudden the status is not updated in IPS anymore when I use the wireless (radio) buttons for all my light switches and/or dimmers . Is this a known issue, or has someone encountered this behaviour before?

Best regards,

OK, it looks like the „ReturnID“ has been changed overnight for all my EnOcean devices. How?
