Connecting to Nucleus

 Find the Nucleus on your network

To find the Nucleus on the network, install the free Roon app on any Mac or Windows PC (available here) or the Roon Remote app for Apple iPad or Android Tablet (available from the App Store and Play Store, respectively). After installation, launch the app from any of these devices and it will automatically discover Nucleus over your home network.

When connecting from Mac or PC, first select 'Continue' under 'I want to use this Mac/PC as a remote control' before you see the screen below. Tablets do not require this step.

On the 'Choose your Roon Server' screen, your Nucleus unit should automatically be listed.

When Nucleus is located

Option 1: Use Roon

Once Roon has found your Nucleus, just click on "Connect" button next to the Nucleus. From here, you can either:

  1. Log in
    If you are new to Roon, or want to start from scratch, continue to the Getting Started Guide.

  2. Migrate from an existing Roon installation
    If you have already been running Roon, and want to preserve your play history and playlists from another Roon Server, you'll want to move over your existing Roon database & settings by following the Migration guide.

Option 2: Load the Nucleus Web Administration Interface

To get to theNucleus Web Administration Interface, you need to click on “Configure Roon OS devices on your network", which will show you a screen like this:

Your Nucleus should be automatically found and listed. Click on its IP address as shown and the Nucleus Web Administration Interface will open in a web browser. 


Roon Remote is not found in Apple App Store or Google Play Store

  1. Make sure your Apple or Android device meets the minimum requirements.
  2. Confirm that your device is actually what you think it is. This is a very common issue, so double check the hardware model numbers printed on the back of the device. 
    1. Apple devices have a model number that starts with the letter A followed by 4 digits. For example, A1203. iPhones can be checked here and iPads can be checked here.

Nucleus not showing up in “Choose your Roon Server” or “Configure Roon OS” screen

  1. Confirm that your Nucleus has been turned on. The white LED above the power button should be lit.
  2. Confirm that your ethernet cable is plugged into the Nucleus and that the LEDs on the ethernet port are on and blinking.
  3. Confirm that your ethernet cable is not damaged or dysfunctional.
  4. Confirm that your Roon Remote is connected to the network. WiFi is fine, as long as it is the same router as your ethernet network.
  5. In a multi-LAN or subnet setup, auto-discovery will not work. You can locate the Nucleus's IP from your DHCP server (your router most likely) and enter that IP into the remote via the "`Why Can't I see my remote Libraries?`" link.
  6. If you cannot connect to Nucleus during the initial setup, the best thing to do would be to review the webUI of the Nucleus, which you can access
