Display Morethx, this worked!
To summerize the workaround:
create a "/storage/.config/system.d/hiddenSSID.service" with following content:
Code Display More[Unit] Description=Hidden SSID Connect Service After=network-online.target connman.service iwd.service Wants=network-online.target connman.service iwd.service Before=kodi.target [Service] Type=oneshot RemainAfterExit=yes ExecStart=/usr/bin/iwctl --passphrase <PWD> station wlan0 connect-hidden <SSID> ExecStop=/usr/bin/iwctl station wlan0 disconnect [Install] WantedBy=multi-user.target
enable the service in ssh with "systemctl enable hiddenSSID.service".
That was it, the next reboot Raspi should connect to your hidden network.
