core Unifi integration: Websocket disconnected

The problem

I get several reports in the log that says: 2025-12-07 03:46:57.785 ERROR (MainThread) [homeassistant.components.twinkly.coordinator] Error fetching twinkly data: 2025-12-07 11:14:40.454 ERROR (MainThread) [aiounifi.interfaces.connectivity] UniFi websocket error: 'No PONG received after 7.5 seconds' 2025-12-07 11:14:40.456 ERROR (MainThread) [homeassistant.components.unifi] Websocket disconnected 2025-12-07 13:53:38.455 ERROR (MainThread) [aiounifi.interfaces.connectivity] UniFi websocket error: 'No PONG received after 7.5 seconds' 2025-12-07 13:53:38.455 ERROR (MainThread) [homeassistant.components.unifi] Websocket disconnected

My connection from my HA system to my modem/routers/switches are all hardwired. I have no clue what causes this, which makes it hard to isolate the problem. And offcourse, how to fix it.

What version of Home Assistant Core has the issue?

core-2025.11 and up

What was the last working version of Home Assistant Core?

unknown

What type of installation are you running?

No-one else report this issue, I would guess it is some kind of environment issue for you otherwise it would be more broadly reported

I am having the same errors logged as well. They have been appearing for a little while (maybe a month or two) and my whole network setup is unifi (router, switch, 3 APs).

The errors appear intermittently in HA, perhaps a few days apart. I'll add my errors when I next see them appear.

Edit: the error appeared again for me

I have a similar error that occurs sporadically. My guess is that it first occurred when UniFi switched the temperature and utilization reporting for the CPU & RAM to “Instant” (which, by the way, is idiotic; reporting every minute would have been more than enough). HA now receives values from UniFi several times per second. In conjunction with the data traffic from other integrations, I suspect that there is an occasional “hiccup” in the connection.

Happens here as well since a week or max two weeks. 2025-12-09 13:59:36.875 ERROR (MainThread) [aiounifi.interfaces.connectivity] UniFi websocket error: 'No PONG received after 7.5 seconds'

Speculation I think they have removed the Websocket option... or changed it. Dont know after what Network app version update... guess 10.x killed it.

I done some research and its not clearly noted in any of the documentation or on their website (not surprised, they s*ck when it comes to information 🥴 ).

I have been trying to figure out how to setup and run a websocket and non of the previous methods are working. Wont get a hold of a CSRF tokens...

The searched continues but... not hopeful.

Not specifically caused by network v10. I upgraded to v10 about a week ago and was having these errors before that on v9.
