Various embodiments are provided for managing and interacting with a conversational agent in an internet of things (IoT) environment by a processor. One or more graph patterns may be extracted from a knowledge graph generated from a sensor list containing one or more IoT sensors. One or more conversation patterns and conversation dialogs may be learned from the sensor list and graph patterns. The conversational agent may be automatically configured with the one or more graph patterns, the one or more conversational patterns and conversation dialogs, sensor data and analytics from the one or more IoT sensors according to one or more queries to engage in a conversation dialog with a user.
