Appdaemon loses connection to HA

Since a while, and most probably from the moment I’ve ugraded HA to 0.116, appdaemon to 4.0.5 and Python to 3.8.6 the HADashboard is losing connection to HA instance, which is demonstrated by inability to trigger scripts from HADashboard and not refreshing new entities (e.g. scripts). It is resolved by restarting appdaemon but comes back again after a while. I have not noticed any errors in the log other than mentioning that it can’t run the script. Any ideas?

Please post the logs. Do you see any websocket or authentication errors in the Home Assistant log? Have you configured all available logs in appdaemon?

How did you install HA and appdaemon, i.e. supervised install, virtual enviroment or docker?

Before switching to docker, I had similar issues from time to time due to conflicting python dependencies.

I have now enabled all logs but at the start they are empty. The appdaemon_daemon.log has no errors for now. Let’s see once it disconnects again. The appdaemon was installed as part of the HA Core community plugin to FreeNAS and so far was working ok. So it is installed in a FreeNAS jail in a virtualenv:

Testing virtualenv...

 CWD: /usr/local/share/appdaemon
 Python 3.8.6
 AppDaemon 4.0.5

And here is the appdaemon_daemon.log:

no errors so far.

Ok, good. You can also add


to your logger config in HA so you can see any websocket error since that’s how appdaemon talks to HA. I would guess the websocket connection goes down for some reason.

OK, I’ve had no logger configuration at all so I’ve added the following:

  default: warning
    homeassistant.components.websocket_api: warning

Let me know if that is good enough

I would set the log level to info to start with.

OK, so here we go. HADashboard cannot run scripts anymore from mode widget. The following is logged in appdaemon_daemon.log. Scripts triggered from script widget work ok:

2020-10-27 18:10:02.612065 WARNING AppDaemon: Unknown domain (default/script) in call_service from stream

nothing in the other log files, they have 0666 access rights but maybe should be different?
Also, nothing in ha log. After restarting appdaemon service all work ok again.

Ok, so it has nothing to do with the websocket connection to HA. Looks like a namespace issue. Check out this thread. Unknown domain (default/remote) in call_service

Seems similar but a bit different. I’ve posted my case in that topic. What is strange is that I can call the same script from script widget but not from mode widget. It happens every time after HA is restarted (entire system) and is resolved after restarting appdaemon service.
