Getting error of 'Adapter disconnected, stopping' every two hours.

[MostHated]

What happened?

I am using a UZG-01 device via PoE. Tthe Z2M docker gives the following error after 1h 59m 55s and does this repeatedly after that amount of time over and over:

I did a continuous port check every 500ms to the UZG-01 on the port Z2M is connecting to, as well as the web interface, my home assistant box, etc, and didn't see the UZG-01's zigbee port go down, nor any of the others I was checking. While the connections were still reporting as up, the following error still occurred and when this happens, often a handful of devices will fall offline.

I have the same issue. Z2M running on an Alpine container on Proxmox. I have also tried running on an Ubuntu container and as Home Assistant Add-on. All show the same pattern, disconnect after 2 hours.

I have tried both with LAN and Wifi, with same result.

As a part of my debugging process, I tried to open a TCP connection towards the UZG-01 using telnet. After 2 hours, the connection is dropped by the UZG-01 with message "Connection closed by foreign host.".

For me the the problem seems to be on the UZG-01 side, with either the ESP32 firmware or the Z-Stack firmware.

I have the same issue. Z2M and Mosquito running on Home Assistant using the SLZB-06 via ethernet.
This is a new setup and the issue is there since the beginning.

I have the same problem. ZigStar lan every 2 hours disconnected. Z2M Current version: 1.34.0-1, ESP 0.6.10, Zigbee
20220218. This is my second zigbee net. First net on USB Zigbee on RFStar CC2562P work normally. I think this problem appeared after the latest z2m update

[dellorianes]

Same here with a tube-zb-gw-cc2652p2-v2 over ethernet.

I changing DHCP lease time for IP adresses on my PfSense router, it was 7200 sec, and problem is gone. But i dont know why DHCP lease time influences on static IP adress my LAN ZigStar. 4 hours ZigStar not disconnect

[comazone]

Make sure DHCP is disabled in coordinator setup

[MostHated]

Oh, really? Interesting. I use PFSense as well (though, that part is probably unrelated). Let me give that a try.

[comazone]

Try this method. May be it work for you too

[MostHated]

Yeah, I was just setting a static dhcp mapping in pfsense, as I do for most everything. I set dhcp off on the device now, and put the address in and it is restarting now. I will keep an eye on it the next 2 hours and see how it goes. 👍

[docstalek]

I have also changed to static IP now. Let's see if that changes anything 🤞

[comazone]

On my clock 23:55, last disconnest was 14:46. Problem is gone

[MostHated]

Yeah, so far I am at nearly 3 hours now, and I don't think it once ever made it past 1:59:00 before. On my end, all I did was change from DHCP to static on the coordinator. I didn't adjust anything on the firewall side. That is quite curious that having DHCP set on the device would cause the container to restart, but I guess it is what it is, lol. Maybe a container restart is automatic if the connection to the adapter is lost?

[docstalek]

Indeed, it worked! Finally a stable solution! 🥳
Excellent find, @comazone! Greatly appreciated! ❤️

So it seems that the ESP32 part has a poorly implemented DHCP client or something and drops all connections when it's renewing the IP lease.

[MostHated]

I am a few moments shy of the 24 hour mark and things have been just fine now. 👍 Indeed, thanks @comazone

[sadabla]

I also use pfsense and static mapping in DHCP for the SLZB-06. Setting a static IP address solved the issue. Thanks a lot @comazone!

[udivankin]

As for me with Hamgeek LAN coordinator built with RF-BM-2652P2 and MJ-Ethernet01 from ColtSmart, setting static IP didn't help.

[mercenaruss]

Guys please open a issue here: https://github.com/mercenaruss/uzg-firmware
We will try to solve the issue.

[ashishpandey]

While static IP works around this issue, should zigbee2mqtt be resiliant to disconnects, specially when an immediate reconnection within a small window of time works? That should help a lot with stability. Sockets drop, this should not be a fatal error

[fliespl]

Anyone else is having this problem even with static ip set? I have had a run of 1 month without issues but then I ve had like 3 disconnections over a week where only device restart helped (uzg-01 with p7 chip).

[MostHated]

Yeah, I thought I was losing my bananas. Ever since I made my last post, things have been working great up to this last month.
It has been quite frustrating. Multiple devices dropping off-line every few days. I feel that it has been better than it was before setting static IP, but during the time it was good, it was great, not a single drop off or anything from Dec 19th until around the start of March or somewhere there abouts.

I am not sure if you are using HomeAssistant, and this could be purely coincidental, but it feels this started when/soon after I installed 2024.3.x.

[mercenaruss]

this is related to p7 chip firmware.

@marcusaram can you explain a little bit more? Is this something that might be fixed in the future? If so where - z2m or uzg firmware?

[MostHated]

I, too, am very much interested in any additional details about that, it was a rather vague statement. Is there something we can do on our end to help with this? Ex: a firmware update or something?

[marcusaram]

Hi, you should probably mention someone else. I did long time ago some small contributions to this project but actually not using zigbee2mqtt anymore. Besides that I've really no idea what is causing this issue 😅

[MostHated]

I am sure he didn't notice and thought he mentioned the name above his. I didn't realize it was wrong either until just now, lol.

[fliespl]

@MostHated @marcusaram Of course I did mean @mercenaruss... Sorry about confusion, very close nicknames :) 🤦
