Can I integrate the Ubiquiti USG with Home Assistant?

Yes, if you own a Ubiquiti USG and you are running Home Assistant, then you really need to link the two together. The primary reason for integrating your Unifi Controller with Home Assistant is to get state information of your devices connected to your network.

If you first configure a Ubiquiti USG via a Unifi Controller then if yo shut down the controller or if it we to go offline, then the Ubiquiti USG will continue to function. The only problem is that any statistics, logs, notification etc. will be lost while the Unifi Controller is offline.

Why is a firewall important?

For the most part, a firewall for a home or small business network should simply prevent people from the WAN from finding open ports and finding out that a network exists at a certain IP. Most hackers are simply using automated software to find networks with vulnerabilities, so this is the most important job for a firewall. The default firewall rules for the USG ensured that this was mostly the case. One issue I did experience is that Ubiquiti left ICMP (Ping) from WAN enabled by default which had to be disabled via the CLI interface.

How much bandwidth does the Ubiquiti USG have?

Despite being powered with an older Cavium Octeon+ CN50xx series dual-core 500MHz processor paired with 512MB DDR2 RAM, Ubiquiti claims the USG is capable of routing up to 1,000,000 pps (Packets Per Second) for 64 Byte sized packets and 3Gbps for 512 Bytes or larger transfers. Additionally, thanks to the lower power components, power consumption comes in at a mere 7W.

Why are UniFi routers configured by site?

Unlike most consumer or small business routers, the reason why the UniFi routers are configured by site is because the UniFi system is designed to be deployed with multiple routers, switches, and access points so this makes it easy to reconfigure everything all at once by setting up a single site configuration.

How to configure USG?

The USG can be configured by clicking on the device under the device screen. This allows monitoring and configuration for the specific device. This includes details on the device, the networks it’s connected to, and configuration of the WAN, port forwarding, DDNS and firmware updates.

What is DPI in USG?

Finally, one of the biggest selling points for the USG is the Deep Packet Inspection (DPI) feature. With DPI enabled, all sorts of traffic statistics can be found such as where the majority of traffic is going, what protocols are used, etc. While not so much a big problem on smaller networks, network administrators on bigger and busier networks can use the data to figure out how to shape traffic in order to ensure a good network experience for everyone.

Step 1 – Swapping routers

I did a 1:1 swap of the existing Linksys router. Wan to Wan and Eth to Eth and rebooted my router and plugged in power to the USG.

Step 2 – SSH login & configure Unifi Security Gateway

Wait until your wired PC gets an IP address. It should be in the subnet. Then SSH with your favorite terminal emulator to The default login is “ubnt” and password is “ubnt”.

Step 4 – Final Step

I already had an existing controller setup on a mini PC with an Atom Z8300 and Windows 10. It would not find the USG so I had to do an extra step. SSH over to the USG with putty and the IP address you gave earlier. In my example, I use with the default login still ubnt:ubnt and run these commands.
