A system for commanding a movable barrier operator, the system comprising: a network-enabled electronic host device (120, 210) located in a vehicle and configured to run a movable barrier controller application and to generate and send, using the movable barrier controller application, a control signal to a movable barrier operator; and an auxiliary device (110, 220) configured for mounting in the vehicle, the auxiliary device (110, 220) comprising: a short-range radio frequency communication interface configured to communicate with the network-enabled electronic host device (110, 220) running the movable barrier controller application; a user input device (111, 223) configured to receive a user input and, in response to receiving the user input, cause the communication interface to send a status change request to the network-enabled electronic host device (120, 210); and a short-range transmitter adapted to send a radio frequency 'RF' signal to the movable barrier operator; wherein the status change request is configured to cause the movable barrier controller application to generate the control signal that will cause the moveable barrier operator to move a moveable barrier and cause the network-enabled electronic host device (120, 210) to send the control signal to the movable barrier operator over a network; characterized in that the auxiliary device (110, 220) comprises a switch for enabling and disabling at least one of the short-range transmitter and the short-range radio frequency communication interface and in that the auxiliary device (110, 220) is adapted based on the switch to selectively send, upon actuation of the user input device (111, 223), one or both of: the status change request to the network-enabled electronic host device (120, 210) and a radio frequency RF signal directly to the movable barrier operator. a network-enabled electronic host device (120, 210) located in a vehicle and configured to run a movable barrier controller application and to generate and send, using the movable barrier controller application, a control signal to a movable barrier operator; and an auxiliary device (110, 220) configured for mounting in the vehicle, the auxiliary device (110, 220) comprising: a short-range radio frequency communication interface configured to communicate with the network-enabled electronic host device (110, 220) running the movable barrier controller application; a user input device (111, 223) configured to receive a user input and, in response to receiving the user input, cause the communication interface to send a status change request to the network-enabled electronic host device (120, 210); and a short-range transmitter adapted to send a radio frequency 'RF' signal to the movable barrier operator; a short-range radio frequency communication interface configured to communicate with the network-enabled electronic host device (110, 220) running the movable barrier controller application; a user input device (111, 223) configured to receive a user input and, in response to receiving the user input, cause the communication interface to send a status change request to the network-enabled electronic host device (120, 210); and a short-range transmitter adapted to send a radio frequency 'RF' signal to the movable barrier operator; wherein the status change request is configured to cause the movable barrier controller application to generate the control signal that will cause the moveable barrier operator to move a moveable barrier and cause the network-enabled electronic host device (120, 210) to send the control signal to the movable barrier operator over a network; characterized in that the auxiliary device (110, 220) comprises a switch for enabling and disabling at least one of the short-range transmitter and the short-range radio frequency communication interface and in that the auxiliary device (110, 220) is adapted based on the switch to selectively send, upon actuation of the user input device (111, 223), one or both of: the status change request to the network-enabled electronic host device (120, 210) and a radio frequency RF signal directly to the movable barrier operator.
