To use the Swisscom Home App on the Apple Watch, you must have installed at least the software version WatchOS 5.0 on the watch. This requires an iPhone with at least iOS version 12.0, otherwise, the Home App will not appear on the Apple Watch.
Currently, it is possible to switch all Smart Home devices on and off under the section "Devices" on the Apple Watch. Please note that only the devices are shown, which can be controlled directly.
By wiping to the left, the "Scenes" view appears, with the possibility of triggering scenes that have already been created. In this way, all devices can be triggered together with the desired action.
