In the summer of 2016 Apple promised to begin selling advanced door locks in the near future. Moreover, the manufacturers of these devices together with the Corporation Tim cook claimed to have tested the integration with HomeKit for a few months.
However, recently Apple removed the category of door calls with your website. This means that if a similar device will be available with support for HomeKit, it will happen soon. It is worth noting that the company engaged in the development of these calls, there are already other products that support iOS, for example, locks. But, unfortunately, this all is over.
