No, monitoring devices cannot be grouped.
The Core Starter Kit for Wyze Home Monitoring includes devices from different product families: a hub, a keypad, and several different sensors. If you add security cameras (Wyze Cams added to your monitoring system) then that adds another product family in the mix.
Currently, there is no way to group different device types together. Sensors can only be grouped with sensors, cameras can only be grouped with cameras, and so on.
