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.

Been running San Ace 120x38mm 0.8A fans for a few weeks now and have been super happy (they're not silent but that's fine since they're sitting in the furnace/HVAC closet in the basement). Just wondering if buying them 2nd hand was a smart move or not. The particular ones I got are rated for 70,000 hours of use and they were in good shape, but I've been wondering if anyone has had any die on them before, and if so after how long?
