We lost our elder cat a few years ago, and it was rough. I sympathize, especially with everything you're going through. He looks like a terrifying force of darkness, remember those times.

I am super surprised it took this long to do this. Seems obvious in retrospect.

The Google Nest community consistently asks for this capability, basically a fan that runs when there is a significant temp difference to mix the air.

I can't wait for the inevitable "made functional" mod.
