The problem

ZHA would stop working after ~30mins after startup with the following: Logger: zigpy.application Source: /usr/local/lib/python3.10/site-packages/zigpy/application.py:85 First occurred: 9:30:48 AM (1 occurrences) Last logged: 9:30:48 AM

Couldn't start application

Not entirely what is happening but it appears that it just stops and no attempts are made again after that.

Have gone back to 2022.6, otherwise my entire zigbee setup is completely unusable so no go. I am not running a wifi zigibee coordinator but a LAN one directly connected to an ubiquiti switch.

I can confirm this issue. EZSP via socket works in 2022.6.7 but no longer in 2022.7.x version because of the above error. Feel free to ask for more debugging if needed.

Same here, but in my case problems seem to have started from any version above 2022.7.0. Rolled back to 2022.7.0 from 2022.7.6 and ZHA is stable again.

Ok, I will double check later today. I may have skipped 2022.7.0

Ok, I will double check later today. I may have skipped 2022.7.0

I'm thinking (but not sure) that 2022.7.1 was fine too, but I'm 100% sure 2022.7.0 is indeed fine as that's what I rolled back to.

A little follow up: over the last hour or two, I've been gradually upgrading HA Core starting with 2022.6.7 until 2022.7.6 and oddly enough, now everything is working as expected. No errors in the logs and the connection to the Zigbee coordinator seems to be stable.

So I'm not sure what to make of this...

Oh bummer, no luck. Still running 2022.7.0 and ZHA is stuck again.

We're now almost a day later and I haven't seen the problem reappear. I have a feeling I am just lucky and that bit of troublesome code was not (yet?) triggered for some reason.

Just for reference, here's what I did and what seems to have fixed the issue:

• Initially I was on HA core 2022.7.6
• in the SSH terminal I downgraded to 2022.6.7 and next upgraded one version at a time:
• ha core update --version 2022.6.7
• ha core update --version 2022.7.0
• ha core update --version 2022.7.1
• ha core update --version 2022.7.2
• ha core update --version 2022.7.3
• ha core update --version 2022.7.4
• ha core update --version 2022.7.5
• ha core update --version 2022.7.6

On every step the Zigbee integration kept working.

Thanks Peter! After the ZHA lockup yesterday I restarted HA (via YAML dev-tools), and since then it's been running without any problems. So maybe the lockup on my side was incidental, I'll keep monitoring.

Status update: ZHA kept locking up multiple times a day last weekend. So I've downgraded to 2022.6.7 last sunday, havn't had any lockups yet.

I haven't experienced any issues, but as I said before, I think that's just luck. I don't have the possibility to dive into the code right now, but I have a feeling there is a bit of code that is triggered when an error condition happens that is not properly handling the error. Probably since 2022.7.0. But that's a lot of guesswork.

I have the feeling you are right. I'm using a Sonoff Zigbee Bridge loaded with Tasmota, connected to ZHA via WiFi, so when the connection between ZHA and Sonoff ZB Bridge is unstable ZHA has to reconnect. It seems as if from version 2022.7.0 and upwards the reconnect is having problems causing ZHA to crash.

I'm running into this as well but using a tube-zb-gw-efr32 running over ethernet so the connection is rock solid. From the device, I'm just seeing Home Assistant drop the connection with the same message. I have to restart home assistant to get it to work again (drops approx. every 30-min)

[D][streamserver:055]: Client 10.1.10.2 disconnected

Looks like we have the exact same issue.

I am having the same problem, "Couldn't start application" error after some time, ZHA network is down which is resolved by a restart. Not sure exactly what version it was introduced but downgraded to 2022.6 and it is back to reliable.

@s2d4 @frenck can someone please add the integration:zha tag so the proper developer can look into this?

zha documentation zha source _{^{(message by IssueLinks)}}

Hey there @dmulcahey, @adminiuga, @puddly, mind taking a look at this issue as it has been labeled with an integration (zha) you are listed as a code owner for? Thanks! _{^{(message by CodeOwnersMention)}}

I've not been able to reproduce the issue today and have upgraded to 2022.8. Will report back if I see it again.

I was able to reproduce the error yesterday and provided the logs to @puddly. Thanks for the new version, will test as soon as it is released!

I also have the same issue, it keeps restarting my mqtt devices every couple of hours sometimes 3 hours sometimes more:

@PirvuCatalin This issue is regarding the process crashing and not restarting and the Zigbee network being down until the user takes some action such as restarting Home Assistant that began with 2022.07.x releases. In your log it appears to restart correctly.

I am getting off topic, but if you're using a Zigbee coordinator that connects via WiFi the connection can in some case be more delicate due to the inherent nature of wireless networks. Low signal strength, too many clients on an access point, co-channel interference, etc. In addition WiFi and Zigbee use overlapping frequencies and even though Zigbee has much lower power levels it is possible in some installations it causes it's own interference. The EZSP protocol is rather sensitive to latency/jitter and dropped packets. Like I said this is getting off topic, but I would start with checking your wifi access point for the RSSI value and any indication of short connection time or connection drops. Even if you're using an ethernet controller the topology of your network could create similar connection drops. I have also seen NCP entered failed state messages from USB devices, for e.g. a Raspberry Pi with an inadequate power supply. Follow up with the Home Assistant Discord or Forums for further troubleshooting.

Thanks @Andrew-Joakimsen , I understood what you said above, but that's not the case, it happened after I've upgraded, no changes in my setup or network. I'll probably downgrade or change my zigbee coord

Please try out the latest HA Core release, 2022.8.2.

Please try out the latest HA Core release, 2022.8.2.

Thanks @puddly. I've just updated to 2022.8.2 without any issues. Will keep you posted about ZHA stability.

Thanks @puddly. I've just updated to 2022.8.2 without any issues. Will keep you posted about ZHA stability.

Still running smoothly. ZHA disconnected during the night (because my Sonoff ZB Bridge has a scheduled reboot at 05:00AM) but reconnected right after without any problems, so far so good.

Thank you for looking into this @puddly

Unfortunately still not working in 2022.8.3, rolling back to 2022.6.x

I should emphasise that mine is not a wifi device and this issues was not opened with regards to known NCP problems with the sonoff ZBBridge.

Complete zigbee outage after the following logs, which differs in content from the logs received on 2022.7.x but a complete outage at the end nevertheless.

Please try adding this to your Home Assistant configuration and restart HA:

zha:
  zigpy_config:
    backup_period: 86400  # remove this after 2022.8.4 is released!

There is a bug with how frequently automatic network backups are performed (new in 2022.8.0), which causes a lot of traffic to your coordinator on startup and then once every 24 minutes, instead of once every 24 hours.

It will not solve the underlying problem with your coordinator "breaking" when there is a sustained burst of data (likely a problem with the ESP8266/ESP32 firmware) but it will at least reduce the frequency of these disconnects until we can figure that other problem out.

The error persists in 2022.8.4. I also tried using an update copy of the bellows module and disabled the bellows UART thread https://github.com/zigpy/bellows/blob/cb11d6cf9175b3a924a0c89ce57c93e4a54dd63c/bellows/uart.py#L357 by changing the True to a False.

Both the blocking sleep call and reconnecting during reconnect failures have been addressed in 2022.8.7. I've been testing with Tube's EFR32 gateway and have only been able to crash it once, with reconnection happening properly afterwards.

I've also added a config option to reduce the number of consecutive watchdog failures needed to handle a disconnect:

zha:
  zigpy_config:
    max_watchdog_failures: 4  # you can reduce this to 1 to immediately trigger a reconnect

Let me know if this release is more stable.

I believe all of the problems related to this issue have been addressed. Can anyone affected by this and running 2022.8.7 (or newer) confirm that stability has improved?

Thanks for all the hard work @puddly!

I cannot confirm this as I've moved over to Z2M in the meanwhile. Hopefully somebody else can confirm the stability.

@puddly Currently I have Home Assistant 2022.9.1 version installed and I have issues with enabling "Zigbee Home Automation". The issue is

Is this simillar to the previous issue?
