Methods and apparatus for use in an Internet-of-Things (IoT) system are presented. A method performed by a network node in an Internet-of-Things (IoT) system is presenting in an example embodiment. According to this example method, a network node or a plurality of network nodes working collaboratively can obtain data captured by one or more IoT devices and associated with an interactive activity with which different participants interface at different sites. Furthermore, the network node(s) may determine a state of the activity by applying the data to a data model. Moreover, the network node(s) can, in an example method, provide one or more feedback signals to feedback devices associated with one or more of the different sites to actualize the determined state of the activity, where at least two of the different sites have disparate, meaning non-identical, feedback device sets.
