The port would also need to be forwarded to the Home Assistant app instance. Currently the app package does not specify any additional ports to be forwarded to it. We need to add this to the package manifest. I don't have any Apple devices to test this. But do you know if Home Assistant needs to respond to the mDNS searches by your Phone or if the server itself needs to be setup to work with mDNS?

I guess the question still remains - will we be able to use HACS with Home Assistant on Cloudron? If not, the Cloudron documentation should state the same.

I am marking this topic as solved. Now hardware devices can be added to the app by the user and it works.

Unfortunately, I can't quite reproduce this here. Do you have an idea, which plugin/module might be requiring PyQRCode so I could test this further?

@rjousse18 whoops, we had a bug in our renovate configuration. However, the tests fail - https://git.cloudron.io/packages/homeassistant-app/-/merge_requests/7 . We are looking into this.

Yes my.subdomain.com works perfectly. and yes i changed the cloudflare dns to the same local ip as the my,subdomain and it is now working. i thought guac would be running on a different ip address to the cloudron machine

Indeed on Cloudron the app needs to specify which ports are forwarded from outside to the app container. Currently HA has no ports setup there. We can easily add port 1400 for this, but it is not clear how this is protected by HA. Is this designed to be used in a trusted home network or fine to be exposed on the public?
