About the Home app on Apple Watch
The Home app 
provides a secure way to control and automate HomeKit-enabled accessories, such as lights, locks, thermostats, window shades, smart plugs, cameras, and more. With your Apple Watch, all your controls are right on your wrist.
The first time you open the Home app on your iPhone, the setup assistant helps you create a home. Then you can define rooms, add HomeKit-enabled accessories, and create scenes. Accessories and scenes that you add as favorites on your iPhone are available on your Apple Watch. See iPhone User Guide for information about setting up the Home app on your iPhone.
Thanks for your feedback.
