I have our home monitoring system set up on MY Wyze app. Can my wife set up a Wyze app in her iPhone and also manage the home monitoring system (and a wide variety of other Wyze devices)??
Yes. Here are the sharing Knowledge Articles from Wyze
Sharing Wyze Devices
If you run into any roadblocks with the Knowledge Articles let the community know and I am sure some additional assistance can be provided.
As a trusted individual in your household she could also share the primary user ID & password, which would give her full control.
