The new app is great (but also struggle with the 'No Response' problem). It's actually the main reason I purchased - as a z-wave to HomeKit bridge.
However, I have z-wave 0-10V dimmers (Qubino) that control fans - it would be awesome if the app could allow them to appear as fans in HomeKit (not lights which is currently what happens).
I also have z-wave chain driven window openers (Fakro) - that opens the window, not a shade, curtain or blind. HomeKit has a Window accessory type, Hubitat does not. I have to drive them as generic window shades inside Hubitat, but would love to see them as windows in Homekit.
