Smart Home devices feel somewhat antithetical to Apple's Philosophy. Aren't they all about a smoothly integrating, tightly controlled ecosystem? Offering something that connects a potentially large amount of third party devices, protocols and homecooked solutions feels odd for apple.

That idea has never really been as true about Apple has people love to claim.

The Home app launched in 2016 (HomeKit in 2014).

The Health app launched in 2014. Both apps meant to work with third party devices/apps and act as a hub of information.
