Creating and fleshing out the smart home can be challenging when shopping around for new devices to add to your automation a***nal, but it doesn’t have to be if you’re smart about it. I have a few old phones lying around, including an iPhone 12, and wanted to use one to create a super-smart sound sensor, which could help cover us while we slumbered peacefully. Turns out, not only was this possible with just a few hacks to get the iPhone communicating this data with Home a**istant, but it works so well that I decided to expand coverage with a second position elsewhere.
