Honestly most smart home devices support HomeKit these days – lights (Philips Hue, IKEA), thermostats (Ecobee), locks (Yale, Schlage), blinds, cameras, sensors. And anything that doesn't can usually be bridged through Homebridge or Home Assistant. It adds up fast once you start – lights alone can be 50+ if you do every room.

Wow. I thought it was just the speakers. Why don't they advertise this?

Every device compatible with the Matter standard[1] can be used with Apple Home (and with every other solution that supports Matter, like Google and Amazon ones), so almost everything is compatible with everything out there.
