We’ve set up alot of smart devices over the years. This is by far one of the easiest We have setup. All the Devices came pre- connected. The only reason to run the setup utility in the app was to name each piece accordingly so you would know which sensor was which. 

Even the mounting systems were easy with screws for the base and keypad. Sensors were all strong double backed tape. 

Also This system is very add on friendly with the ability to add sensors, cameras and more.
