A simple utility to generate signed certificate files to allow local control of a Lutron Caseta smart bridge.
About
This add-on will guide you through the necessary steps to create signed certificate files necessary to control your Lutron Caseta smart bridge with Home Assistant.
Three files will be created during successful execution of the wizard:
/ssl/lutron/caseta.key: the private key file used to generate the certificate.
/ssl/lutron/caseta.crt: the signed certificate file used to connect to the Lutron Caseta bridge.
/ssl/lutron/caseta-bridge.crt: the certificate authority file that is downloaded from the Lutron Caseta bridge.
Be sure to add Lutron Caseta to your configuration.yaml after starting the add-on:
The primary goal of our add-ons project is to provide you (as a Home Assistant user) with additional, high quality, add-ons that allow you to take your automated home to the next level.
For me it gives me a 500 Internal server error, but still generates a caseta.key file. I am missing caseta.crt and caseta-bridge.crt. Here’s my log output:
I found it, and copied the files into my config folder - having no luck with this. I’m getting the following error:

When trying to run the add-on, I get a 500 Internal Error:
Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.
Below is from the log. Can anyone help me out and whether or not this add-on is still functional or if there is a workaround?

Hi. Thanks for this. Installed flawlessly. No errors. Log looks fine. One problem I am seeing is HA does not seem to be able to track the status of a device. I can turn it on but that’s pretty much it. Am I missing something?
@TurboJones, yes, I believe I just started completely over with the bridge. Since this was the initial install, it was no big deal. IIRC, I believe you have to take the url from the 500 error page and post it into the Cert Web UI.
Thanks. It’s good to know I’m not the only one. I’ve manged to get things working for now through the SmartThings integration, but it’s a bit of a kludge, plus the HA is local (I think) which I prefer.
