Halt app on Home Assitant complement

deCONZ General Support
1

Hi.
I have a Conbee II usb into a Raspberry Pi 3 running Home Assistant OS. Its plugged through an extension usb cable as recommended
Deconz complement and integration installed and working all Ok (i have this setup since 2019).
Suddenly, all the devices linked to the Conbee sttoped working. I’ve not updated nor touched anything. I have disabled automatic updates for the complements and also for the OS itself since many months ago.
Looking the Deconz complement addon i can see its stopped everytime this happens. Checking the app logs i can see there’s a problem that says “Halt app”, then sometimes the complement restarts itself (as enabled in the settings) but sometimes it just stops and is no longer starting until i do it manually. In both cases thats so annoying, because i loose the funcionality while reatarting or ill loose it until i interact.

I’m not able to see whats causing this, my knowledge its not enough, but until now I’ve tried:

Uninstall and reinstall the complement, and the HA integration.
Update the complement to the last version.
Reset the Conbee.
Change USB port.
Change Zigbee channel.

None of that is solving the problem.

Here’s a piece of the log:

Its someone able to put some light into this trouble ?

Sorry, but it looks like the app and integration need to be reinstalled (remember to back up your Phoscon data). See here.

3

I’ve done that, posted in the OP.
Works for a few hours, then suddenly go back to the same issue.

4

First, you should not change the Zigbee channel because some devices do not automatically adjust the channel and may need to be reconnected.
To find the actual problem, you should change the log levels to document the error.

5

I’ve changed channel just to test and try. All my devices are working correctly no mather what channel i use, but thats not the problem.
I can’t see any option to change the log level on the deconz complement.
Or you’re meaning on the HA system ?

6

See the app documentation.

7

I suppose its dbg_error but…can you please point wich one of this i must enable ?

dbg_info
dbg_aps
dbg_zcl
dbg_zdp
dbg_ddf
dbg_dev
dbg_ota
dbg_error
dbg_http

Thanks for your time and patience.

8

I would start with dbg_error and dbg_http. If a restart then occurs, the messages before that are of interest.

9

Hello, wich one deconz version are you using ?
As the bug is rapid, try to install deconz on another machine and move the conbee (and migrate the database).
You can configure HA to use this second installation, but this will help to see if the problem is from the deconz version, your database, or the host.

10

Enabled, waiting for the next halt issue.

11

Right now, using the last available deconz version. But was happening also on earlier version.
I dont have any other resources on to install HA to try your way.

@Smanar Excellent point.
You don’t need HA; deCONZ can be installed and run on many systems (e.g., Windows, Linux, and macOS). So if it happens again, you should also rule out the database. The Phoscon homepage and Google can help you with that.
