Aggregator devices and methods are disclosed for establishing device interaction in an environment containing other electronic devices and the aggregator device. The aggregator device has a transmitter, receiver, memory storing interaction rules, and a processor for implementing the interaction rules in association with the transmitter, receiver, and other devices of the environment. The methods involve transmitting a message to the aggregator from a first device, referencing rules of device interaction for the environment, and then according to the rules of device interaction, transmitting a message from the aggregator to a second device. The rules of device interaction may include instructions that are to be transmitted from the aggregator in response to the aggregator receiving change of state messages from devices of the environment.
