This is because another company has not done it well enough yet for Apple to borrow their idea and improve upon it. That is largely how Apple works (Look at HomePod, iPhone, etc...), let someone invent an idea/process/service, then take that idea and make it better. Home automation is still trying to take root, give it a few years and Apple will have a strong product here I believe.
