An object monitoring system includes a plurality of wireless sensor devices and at least one user device A method for controlling a response time of one of the wireless sensor devices in such a system includes determining one or more metrics representing a present state of an object; and calculating a probability that one of at least one user devices will interact with the wireless sensor device within a pre-determined time period by executing a trained model with the one or more determined metrics as input and controlling the response time of the wireless sensor device based on the calculated probability.
