Hey Siri, what happened to HomeKit?

No mentions of HomeKit at Apple's Special Event could be because so many product updates were announced. Or perhaps not all hardware partners are convinced a proprietary platform is the way to go.

Zero.

That's the number of times I heard the word "HomeKit" uttered during the Apple Special Event presentation on Wednesday.

Admittedly, I was taking notes and writing while viewing the event, which lasted more than two hours, so perhaps I missed it.

I suppose I could go back and watch the recording but even without doing so, it's clear that HomeKit wasn't part of Apple's focus yesterday.

Instead, it was all about Apple Watch updates -- new bands, colors and WatchOS 2 app demos -- the ginormous iPad Pro, the iPhone 6s and 6s Plus, and (finally!) an updated Apple TV with apps.

That's a slew of product updates to be sure and even though the Apple TV announcement was aimed at content control, we already know that Apple TV can provide remote gateway access to HomeKit devices. But not even that was mentioned.

Is it possible that there was just too much in the way of product updates to warrant any HomeKit updates or demos? Absolutely. Not talking about HomeKit at all, however, seems odd to me.

At this point, the HomeKit platform is nearly 15 months old. Yet you wouldn't know it by the amount of -- or rather, lack of -- products that actually support it.

To be sure, as a new software platform with specific hardware requirements won't take off overnight.

Even so, evidence suggests that HomeKit was a bit of a moving target for Apple's hardware partners. Because Apple is requiring hardware-based security -- something that perhaps it decided to do after the original HomeKit announcement -- certified HomeKit devices are hard to come by.

In fact, there are new smarthome hubs launching soon still without HomeKit support.

Consider the one from SmartThings, which was announced last week: It has a faster processor, a battery backup and offline smarts but still won't have HomeKit support when it arrives on store shelves next month.

Speaking to Mashable, Alex Hawkinson, CEO of SmartThings said there are still few HomeKit products for the hub to support and that "Our other hesitation is the proprietary nature of HomeKit. We like most open."

I wouldn't bet against Apple's potential success in the smart home industry, of course. However, it's becoming clear that HomeKit is still a work in progress of sorts: Both in how it will work and who will work with it.
