I know not everyone will favour third-party solutions, preferring to stick with official support only.
But if that sort of thing doesn’t phase you, there’s always the open-source Homebridge software. Which you can run on Mac, Windows and Raspberry Pi to name just a few.
Basically it acts as a hub, allowing hundreds of different internet-of-things devices which don’t have official HomeKit support to work within the Apple ecosystem.
I love it, been using it for a long time now. I’ve got my Harmony Hub, Lights, Cameras and even iKettle and Smarter Coffee machine hooked into HomeKit with it. Because yes, I am so lazy I want to just ask Siri to make me a coffee in the morning while I’m still bleary eyed in bed and have it ready when I go downstairs
