For best performance of Siri utterances, commands often require your Wi-Fi and BLE to be enabled on your iOS device. Often users may need to go into iPhone settings ->General -> then Siri and toggle OFF, then On for Siri and try the commands again. You may need to use the word “detector” as Siri recognizes the word “Alarm” as the alarm clock function on the iPhone. If you have multiple homes in your app, you can only use SIri on the Primary Home. You can toggle which home you want to set as primary through the home settings.
