    Thank you for your reply FURRYe38 !

     

    I tried different browsers on different Systems (PC, Mac, iPad) until I found the problem.

    It looks like a input validation issue in the web frontend. I tried to add a device which was shown in the DHCP server with a device name with underscores "Meross_Smart_Plug". If I replace the underscores with e.h. dashes, it works as intended.

     

    The frontend has no problem with submitting a device name with underscores or blanks but the backend does not accept the request. An input validation seems to be missing. I've found it by trial and error but I think this should not be the intension of the user interface.
