It sounds like you only need to add a device. You can add this device
manually. Go to 'Nodes' > 'Devices' > 'Add device'. You will need to
specify the MAC and IP assignment for your device. For example, you want
your device to have an specific IP address, you can select 'Static' IP
Assignment. If you don't care which IP it gets, select 'Dynamic'. This will
automatically create a DNS entry.

By default, the 'device discovery' feature has 'Passive' scanning active.
This will only listen for ARP request. It may be the case that MAAS is
missing the specific ARP request. That said, however you can go to the
subnet where your device is and you can select the action to 'Map subnet'.
This will have MAAS scan the network via 'ping'. If you have 'nmap'
installed, it will prefer nmap over ping.

Please see for
further explanation.
