Ah, that would make sense. Too bad I had to upgrade to Nvidia since I do 3D modeling.

I had a ton of trouble getting my R9 390 working on Linux, so ymmv

I never had dht-11s that worked at all. Maybe one in ten was anywhere close to calibrated correctly. I need to check out the bme280, though.

For the most part I use SHT-35s with esp chips, although I got the Govee sensors with a base station for our reptile enclosures.

We’d need to see the logic of your automation to help on this one. The full graph would be good too.

But, why use an automation as a thermostat instead of a generic thermostat integration?

I use a culligan inline filter to a separate tap on my sink.

Having an oversized furnace really isn’t a bad thing, and only having it run half the time sounds like a good thing to me.
