Electronic systems are provided for secure actuation of a remote device such as a moveable barrier operator. The systems address the “man in the middle” problem of persons intercepting and duplicating radio frequency signals from a control device by introducing timing parameters into a bidirectional communication sequence between at least two devices.

Techniques for enabling a user computing device to manage a controlled device only when the user computer device is physically proximate to the controlled device are disclosed. The controlled device repeatedly provides codes that change at select times and the user computing device sends the last received or captured code back to the controlled device. The user computing device is enabled to manage the controlled device when the most recent code sent by the user computing device matches one or more codes most recently provided by the controlled device. Additionally or alternatively, the user computing device is enabled to manage the controlled device when the user and controlled devices connect to the same access point. A technique for enabling the user computing device to share, mirror, or cast a screen on the user computing device onto a display of the controlled device is also disclosed.

A trainable transceiver for controlling a remote device includes a transceiver circuit configured, based on training information, to control the remote device, a communications device configured to communicate with a mobile communications device, an output device, and a control circuit coupled to the transceiver circuit, coupled to the communications device, and coupled to the output device. The control circuit is configured to receive notification information from the mobile communications device via the communications device, and wherein the control circuit is configured to generate an output using the output device based on the notification information.
