Can't get Lutron Caseta integration to connect on x86-64 HAOS server, but works on RPi HAOS

Third party integrations

I’m planning to migrate from my existing bare metal Debian build because I don’t want to have to deal with the Python version incompatibilities any longer.

Since I had an RPi going spare I did a test build using HAOS, and also added the Lutron Caseta integration which I hadn’t previously used. This was seamless on the RPi box, which is presently running 2025.2.4.

I then did an x86-64 HAOS build (also 2025.2.4) on the new hardware I have for the HA server, and followed the exact same build steps as I had documented for the RPi.

This immediately detected the Caseta hub, but every time I try to pair it I get the can’t connect error.

I’ve factory reset the Caseta hub, and deleted the Home from the Lutron app, and even added in a different Caseta hub, which had never been installed in my environment before, so there shouldn’t have been any existing pairing going on, but I get the exact same issue with this hub as well.

I guess I could go through the process of generating the 3 certificate files manually, but it seems that with the latest version of the integration that it really shouldn’t be needed any longer. The RPi has no problem getting the files from the hub, but the x86-64 machine doesn’t want to play ball at all.

Anyone have any ideas how to solve this?

Since I really need to get this up and running I figured I’d go the route of using the pylutron-caseta tools to get the certificate files manually and then adding the entries into configuration.yaml.

When I try to manually add the integration in order to see the devices I get the following:
Translation error: The intl string context variable “host” was not provided t…
Clicking on this I get:
Failed to import Caséta bridge configuration.
Couldn’t set up bridge (host: [caseta bridge ip address]) imported from configuration.yaml.

In the logs I can see a little more, which is as follows:
Failed to format translation for key ‘component.lutron_caseta.config.flow_title’ in language ‘en-GB’. Error: The intl string context variable “host” was not provided to the string “{name} ({host})”

So at the moment I can’t add the Caseta bridge via auto-discovery or manually though yaml code, which is annoying as the auto-discovery and pairing worked straight out of the box on the RPi HAOS build and this is a new x86-64 HAOS build.
