At&t devices physically installed but not paired with system
I don't have any third party devices I'm trying to add but I do have At&t devices that for some reason were not paired to the app from the start such as my two keypads, carbon monoxide detector, a couple of window sensors, and flood detector. When I go into the app and click on "Devices", I see most of the equipment but not all of them. Can someone show me how to pair these up with my system? Again these devices were installed by the tech but I guess never tested and made sure to be paired before he left. Any help would be appreciated. Thanks.
