The problem with that approach is that Wyze hasn’t really implemented Android Notification Channels in a way that allows users to control the experience in a truly useful way (see Customizable notifications (Incl: Android Notification Channels)). If @trkmsa’s sister is using Android, then it’s possible for her to selectively silence/dismiss notifications from specific devices, but that involves the use of a third-party notification interceptor app, as has been discussed previously in this topic and others. If using iOS, then I’m aware of no such solution. This is something Wyze should’ve fixed a long time ago, and I just asked one of the cofounders for an update in another topic.
