@lauwie007 It’s a new feature we added a while ago - at the moment, unfortunately, you need to set it when registering the devices and cannot be changed later. So you would need to re-add the devices to make it work.
Let’s set up a call and we can go through some options regarding the different end-points with multiple projects. Please just send me an email to florian@iotcreators.com with some meeting proposals.
