The iotty Smart Switch does not currently support integration with Apple HomeKit. We anticipate to offer this integration by late Q2 of 2021. However, we do support integration with Siri Shortcuts. From within the iotty app you simply record the Siri shortcut you would like to use and save what actions you want to occur when Siri receives the command. For example you can create a shortcut so when you say "Hey Siri, I'm home!" your lights come on.
