That's because home automation devices that are compatible with HomeKit, which is the system that enables smart gadgets to be easily controlled using one app or via Siri voice command, are in short supply.
When Apple introduced its HomeKit plan back in 2014, Craig Federighi, senior vice president of software engineering, said that the company was working with the leaders in home automation devices as he showed a slide that mentioned more than 15 manufacturers.
But there are fewer than 20 accessories that work with HomeKit from only five manufacturers, according to the company's website.

Apple had previously planned to allow device makers to run their own security solutions inside peoples' homes, but the company shifted gears and is now requiring manufacturers to integrate Apple-certified chips and firmware into their products if they want to be compatible with HomeKit, according to a report from The Register.
