The invention generally relates to a gateway device (102) that operates as a hub or base station to provide for remote monitoring and control of a barrier operator (104,106) such as is used to operate a powered garage door. The device (102) includes a processor; a data storage device; a network interface for connecting the gateway device to a computer network (114); an operator interface for communicating with the barrier operator; and a computer program, which when executed on the processor: permits access to the gateway device over the computer network by way of a mobile application installed on a mobile device (108); transmits control signals received over the computer network to the barrier operator (104,106); and receives monitoring signals from the barrier operator (104,106).
