Been using the Venstar colourtouch T7900 for a while now and was very happy with it. But ever since configuring HomeAssistant with my local Certs/Authority (I run it all local only and access remotely via Wireguard), it won’t communicate with HA anymore. I updated the firmware and rebooted it and it came back for about a week but has since become unavailable again in HomeAssistant and rebooting fails to fix it anymore.
anyone else have this issue. or am I missing something here?
side note/context: I have both the thermostat and HomeAssistant configured with static IP addresses, if that matters at all.
Very probably related to rolling your own CA. This never goes well since you can’t add the root CA to these devices.
The way to do this is to use an SSL proxy in front of HA for your front-end connections, leave the HTTP port open, and control access with ACL/firewalls your proxmox or networking config.
