Raspberry Pi Unifi Controller Setup

Ubiquiti (and their Unifi gear) have become my go to for just about anything network related. Their gear is feature rich, rock solid, and seems to really “just work”.  We couldn’t be bigger fans.  Since Unifi gear runs a Software Defined Network (SDN), it is not configured like traditional routers and switches via a command-line or on-device web GUI, rather it is configured from a controller running on a separate computer.  This controller has its own web GUI and allows you to configure the entire network, a single device, or access a command-line interface if needed.  Normally you’d need to buy a cloud controller, setup a dedicated virtual machine, or install the controller on your desktop PC. In this tutorial, we’ll go through the very simple process of setting up a Raspberry Pi Unifi Controller. It’s easy!

Running the Unifi Controller on a Raspberry Pi

The Unifi controller uses the Java Runtime Engine. This means it can be installed on a multitude of platforms, even platforms of different hardware architectures. This makes setting up a Raspberry Pi Unifi Controller super easy.

Parts List for this Tutorial

Here’s a handy parts list for you if you don’t already have a Raspberry Pi.  These links cost you nothing, but we earn a tiny commission if you use them. Thank you so much for your support!

For this tutorial we used the Raspberry Pi 4 kit, but most any Raspberry Pi will work for this project.

Getting the Raspberry Pi Unifi Controller Ready

Before we install the Unifi Controller software, it is important that we update the Raspberry Pi operating system to the latest version.  Almost 100% of the issues we see are caused by Raspbian being not being up to date.

To update Raspbian to the latest version, we need to run the following commands:

sudo apt update
sudo apt upgrade

If your Raspberry Pi is extremely out of date you’ll either need to run apt-get full-upgrade, or better yet install a fresh version of Raspbian.

Once your Raspberry Pi is up to date its time to install rsyslog and its only a single command.  If you get a message that it’s already installed, then your good! Some versions of Raspbian already include this package by default.

sudo apt install rsyslog

Installing the Java Runtime Environment

As mentioned, the Unifi controller requires the Java Runtime Environment (JRE) to execute.  The JRE is like a middleman between the controller software and the independent CPU architecture of your device (in our case a Raspberry Pi).  We’re going to install the headless version of the JRE.  This means there is no GUI.  If you’d prefer a GUI just remove “-headless”:

sudo apt install openjdk-8-jre-headless

Installing the RNG-TOOLS (Optional, sort of)

The Unifi support forums are loaded with complaints of the Raspberry Pi Unifi Controller taking forever to startup and running very slowly.  This is almost always due to the RPi not having enough entropy to generate proper random numbers required by the controller.  Think of entropy in this case as the amount of randomness to the numbers generated. While you can run the controller without these next steps, we don’t recommend it!

Start by running the following bit of code to install rng-tools.

sudo apt install rng-tools

Now we need to edit the configuration to make a quick change:

sudo nano /etc/default/rng-tools

Find the line with #HRNGDEVICE=/dev/hwrng and remove the # from the front of the line. To look like this:


The Raspberry Pi CPU is based on ARM architecture and has a built in random number generator.  This gives enables the ability to use it properly.

The last thing we need to do is restart rng-tools (or just reboot the Raspberry Pi):

sudo systemctl restart rng-tools

Installing the Unifi Controller on the Raspberry Pi

It’s now time to actually install the Unifi controller onto the Raspberry Pi!  Whew!  To get started, we’ll want to run the following command.  This adds the Unifi repository to Apt so that we can pull the correct code from the right places.

echo 'deb https://www.ui.com/downloads/unifi/debian stable ubiquiti' | sudo tee /etc/apt/sources.list.d/100-ubnt-unifi.list

In order to access that repository, we need to add the keys that Ubiquiti publishes on their website.  This prevents imposters from posting fake code to the repos.

sudo wget -O /etc/apt/trusted.gpg.d/unifi-repo.gpg https://dl.ui.com/unifi/unifi-repo.gpg

Once again we need to update Apt.  There are new repos now available that it doesn’t yet have lists for:

sudo apt update

Finally we really can install the Unifi controller with one simple command!:

sudo apt install unifi

The great thing about installing Unifi like this is that it automatically gets installed as a service (and hence will automatically start every time the RPi is rebooted). It takes all of the configuration work out of it.

That’s all there is to it!  If you already know how to setup a Unifi Controller, then you’re golden at this point. If not, keep reading and we’ll walk you through getting started with a Raspberry Pi Unifi controller!

Configuring the Raspberry Pi Unifi Controller

To access your new Unifi Controller you’ll need the IP address of your Raspberry Pi and go to https://YOUR.IP.ADDRESS:8443.  If you don’t already know the address.  You can get it from the command line by typing:

hostname -I

In our case the IP address is  So we enter:

Raspberry Pi Unifi Controller Enter IP Address of Controller

If you skip the “s” in https you will get an error telling you so. You will also likely get a security error from Chrome.  Click advanced, and then click “proceed to [YOUR.PI.IP.ADDRESS] (unsafe)”. It’s perfectly safe since we know for sure it is our device.

Once you click proceed you should you’ll be greeted with new Unifi controller setup screen!

On this screen you’ll need to enter your new Controller Name, click agree to the EULA, and then click next. In our case, we’re going to name the Controller “GeekPubUnifi”.

Next up Unifi will ask you for a username and password. Either use your UI account, or click Switch to Advanced Setup and create a local account.

Whatever you like will work here, but select a super strong password.  This is your network controller after all!

Once done click next.

create unifi account

On the next screen the Raspberry Pi Unifi Controller is going to ask you for if you’d like to backup automatically, and optimize your network automatically. We recommend you set both of these to ON (default).

And then click next.

At this point you’ll be configured with the option to configure new devices.  In our case we don’t have any devices on the network that are not already adopted by a controller. If you have un-adopted devices, you’ll see them here!  If you’re moving your devices to this controller, you’ll need to “forget” them in the old controller first.

Click next.

Configure new devices

And now it is time to configure your WiFi settings that will get propagated to all Unifi Access Points on this Controller/Site combination. If you don’t plan to use Unifi APs you can click skip. Otherwise, enter the name of your network and a password.  The name will be your SSID, so choose wisely.

I highly recommend keeping your 2.4Ghz and 5Ghz in sync by clicking “Combine 2 GHz and 5 GHz WiFi Network Names into one”.

Then click next.

Unifi WiFi Settings

You’ll now be offered the chance to review your settings and make any changes.  You can change the Time Zone and Country here if it is for some reason incorrect.

Click finish when done.

And with that you are done!  You now have a Raspberry Pi Unifi Controller up and running.  You can start adopting Unifi devices such as Dream Machines, Switches, Access Points, and more!
