Hi, I have read in the docs that the HomeAssistant integration is known to have issues with self signed certificates. So currently when I want to make an integration with my R3, the status of that integration is ‘connecting’.
I think I have to drop my self signed certificate, or try something with NGINX maybe.
But, before I try that I wanted to ask here if someone has integration in R3 with HomeAssistant working while HA is using a self signed cert? (probably not but it’s worth a shot )
I did some more reading and trials. As mentioned in one of the threads here I first tried to connect with the websocket via a browser plugin, that failed.
It turned out that I had to add subjectAltName when I created the privkey and fullchain certs. After that, using the browser plugin, I could connect with the HA websocket and right away validate the token, in that browser plugin I got a nice
{“type”:“auth_ok”,“ha_version”:“2025.6.1”}
so now Im sure that the websocket is responding.
So, I tried to add the HA integration to R3, again it failed. I see in the R3 logs:
When I want to connect to HA GUI I first have to add that fullchain.pem to the trusted roots on my laptop, restart browser and then I have an https connection with HA GUI.
Is there some way to add this fullchain.pem to the trusted root certificates in R3? Maybe that is the way to use wss with my own self signed certs., any ideas/suggestions?
