Can you please click on the “Apparatinformatie” hyperlink above the zone with the issue and share a screenshot of what it says there? Is there any change in behavior if you reboot your Core?
Thanks for the screenshot. Can you to click on the settings (cogwheel) button next to the zone and see if you have the option to re-identify the device?
Thanks for checking @Frank_Hermsen. In this case, I will escalate your case over to our hardware team, once we hear back from them I or another support staff member will reach out once more.
