Yes I run Home Assistant too. Also got quite a bit of devices on Aqara's platform, and a device each on Ewelink, Tuya, Meross which all technically are a platforms. There's probably another 5 devices with their own apps. Tasmota + Home Assistant is the only one I'm happy about.

Home Assistant (with all its dumb quirks) at least makes an attempt to integrate them. Some FOSS devices I've exposed to HomeKit for presence automation, but seeing Siri is going nowhere I don't think I'll continue.
