Stephen Nellis of Reuters has penned an article examining the difference in how Apple and Amazon approach home automation. Hardware manufacturers who want to sell HomeKit devices must include special chips and produce their accessories in Apple-approved factories. After that, manufacturers must send their devices to Apple for a lengthy approval process. By comparison, getting a device to work with Amazon’s Alexa personal assistant requires just a software review. Getting a “Works with Alexa” label requires hardware testing, but that can be done by a third-party lab and takes no more than 10 days. As a result, Alexa threatens to overwhelm HomeKit with the number of compatible devices, but Apple’s approach leads to easier setup, higher security, and better compatibility. Also, Apple HomeKit devices do not require an Internet connection, which improves both security and response times.follow link
