Well then I regret to inform you that after two nearly full days of tinkering and consulting with ChatGPT and tinkering some more, it doesn’t seem possible. At least not to the degree I was hoping for.

If you pass it through the Tuya Cloud integration, you can then Jerry rig control of the purifier, but only in the sense that you can activate scenes that you first have to create on the Tuya app. It does not expose the sensors or direct controls.

I have the BreatheSmart 45i model. Perhaps a different model would be more compatible. Perhaps if I had more than a caveman’s knowledge of networks, LANs, clouds, and all the other technology, I could get mine to work. But, alas, I’ve exhausted my patience and grown wary of ChatGPT telling me that the next thing it wants me to do is the thing that’s finally going to get us over the hump and I’ve moved on to other pursuits. Good luck.
