A lot of Failed to read state and publish state

[JC38]

What happened?

My network is made with a Smlight SLZB-06M controller and 77 Nous - A1Z sockets.
All A1Z are connected with availability ok and all last seens below 3 minutes. But some are not sending their state (Failed to read state) or are raising a Publish state error.
I have tested all the 2024mmdd Zigbee available firmwares from Smlight, opened a ticket with their support but without solution from their side, except saying that the issue could be Z2M.
Regarding Z2M, I built the network with the 2.x and upgraded it with all the official versions. Today, I switch to the dev branch before opening this issue, and the issue is still there.

What did you expect to happen?

I have no idea where the problem is coming from, the controller , the software, the endpoints (all the sames).

How to reproduce it (minimal and precise)

No response

Zigbee2MQTT version

2.1.1-dev commit: 0d193eb

Adapter firmware version

7.4.5 [GA]

Adapter

EmberZNet firmware 20241127

Setup

Proxmox LXC

Debug log

Same. Seemed to coincide with setting up DIYhue and updating HA core to 2025.2.5

UPDATE!
Turned out to be my unifi 2.4ghz wifi. It randomly flipped to a channel that started causing interference with the zigbee network

It can't be HA as we can see the issue into Z2M without having to get HA running.
For the interference, I choose the 25 which is away from the 2.4 Ghz.
Here is a screenshot of the map, and the info that are displayed on the right of the Z2M UI
I will also add a full log in debug because the first one was only set to record errors.

It might help to look at #22516 as this issue has been reported multiple times.
The solutions vary from setup to setup.

Perhaps the issue is with device 0xC1A7 (49575)
