Ubiquiti devices stuck in "Adopting → Offline" loop on HAOS Unifi Add-on

[tommdq]

Hi everyone,

I installed the Unifi add-on for Home Assistant OS from scratch and followed both the manual and automatic adoption methods — including setting the Inform Host Override parameter — but I always end up with the same issue: a constant loop of “Adopting → Offline” for all my devices.

---

Setup

• Add-on: Unifi Controller (HAOS add-on)
• Devices:
  • U6-LR
  • USW Lite 8 PoE
• Environment:
  • Everything freshly installed and updated
  • Both Home Assistant and devices are on the same network
• Tried multiple restarts, removals, and re-adoptions

---

Symptoms

Devices appear as “Adopting” in the Unifi UI, then go “Offline”, and repeat endlessly.

What I’ve tried

• Full uninstall/reinstall of the add-on
• Factory reset of both Ubiquiti devices
• Checked inform URL points to correct local IP and port (http://<ha-ip>:8080/inform)
• Disabled/reenabled Override inform host
• Rebooted both devices and HAOS

Is there something I’m missing in the configuration or a known compatibility issue with the Unifi add-on on HAOS?

Thanks in advance for any guidance!

I just went through this... If you have SSH access to the wifi unifi device, use "http://:8081/inform" with the "set-inform" command. Ha-OS remaps port 8080 to port 8081, and port 8443 is using a self-signed certificate that is not accepted by the device on adoption. So, use 8081.

IE: set-inform http://1.2.3.4:8081/inform

the log on the device itself at /var/log/messages helped me quite a bit figuring out what was happening in the adoption process.

You might have fixed your issue, but for anyone else that comes along with the same problem, this is how I fixed mine.
