I just picked up two of these https://www.amazon.com/gp/product/B08L85XD7N/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1 to replace some older fans and I’m impressed how well bond is integrated with the fan and how easy it was to add to the app. Setup with home assistant (and exporting to HomeKit) was seemless (unlike the physical installation instructions for the fan itself).
I’ve got a PR open to add BPUP support to Home Assistant to keep it in sync faster
