In addition, HomeKit lets the Wemo app and the Apple Home app communicate with each other which is important because the Apple Home app helps connect Wemo® devices to your Wi-Fi when you set them up. The Apple Home app can also control and automate your Wemo devices.
Why allow access to your Home Data?
Allowing access to your Home Data lets you do the following:
-
Set up your Wemo devices quickly

Control and automate Wemo devices with the Apple Home app
-
Control your Wemo using your voice with Siri®
-
