Abstract: A server-based system includes a server that is a centralized Internet of things (IoT) aggregator, broker, and control system, with a concierge function. The system allows any number of IoT devices and user interface devices to be placed on a single network, where the system translates data received from the IoT devices and the user interface devices into a single data standard, having a standardized language for each of the IoT devices and the user interface devices. This allows all of these devices to communicate and react to one another in an open fashion, and any user is afforded an opportunity to react with various things, such as public objects, as the user moves about to different places around the world. Additionally, a user may add another user to a Guestlist for a place, thus giving that other user limited control over the IoT devices in that place.
