Abstract: The disclosure reveals a system and approach for remote health monitoring and diagnostics of room controllers, networks and devices. A master room controller may be used to open a system health page or a diagnostic page for other controllers. A system health page may provide an overview of virtually all of the other room controllers. A tool of the present system may be used to trouble shoot issues remotely at another room controller in lieu of doing a visit to the respective room controller. A user may navigate from the system health page to virtually any place on the room controller to diagnose issues. The navigation may be done by hyper linking from the system health page. The healthy controllers may be hidden from the page so that the unhealthy systems can be viewed in one shot.
