I am developing Smart Home in Google Home
After sync devices in google home. everything working fine with Google Home Application(https://play.google.com/store/apps/details?id=com.google.android.apps.chromecast.app&hl=en)
But when I access through voice command(okay google, turn on/off all lights/ ) then it says device not available.
If the device is not available then it should also not work from GUI of google home application. but it's work.
