I'm developing the smart device handler using Google Home Local SDK. How do I force device to reload and restart the app? (now I have to unplug the power cord, it does not looks good as it sparks)
Currently (during developer preview) you have to reboot the Home device to reload your local app. In an upcoming release, you will be able to refresh your app inside of Chrome DevTools but there is currently a known issue preventing this.
While unplugging your device may be the fastest way to reboot it, you can also reboot your device from within the Google Home app. Select the device, choose Settings, and you'll find Reboot in the overflow menu in the app toolbar.
I have a couple of Google Home devices, how do I tell which of them should execute requests, is it possible to pin 'master' device?
Local execution currently relies on the Home Graph to determine whether to send a command locally. If the Home device and end device are configured in the same room (and the device can be locally identified), then
EXECUTE will be sent locally.
