Systems are provided for secure actuation of a device such as a moveable barrier operator. In certain embodiments, portions of communications are configured in order to cause information to be added to or deleted from a memory of one of the devices.

Security system for a moveable barrier operator

In one aspect, a method is provided of effecting secure communications for a movable barrier operator and a trainable transmitter. The method includes, at the movable barrier operator, transmitting to a remote control a first radio frequency communication via a first communication protocol wherein the first radio frequency communication includes an access code. The method further includes receiving from the trainable transmitter a second radio frequency communication via a second communication protocol. The second radio frequency communication includes a derived access code based at least in part upon the access code. The method further includes learning the trainable transmitter in response to the derived access code corresponding to the access code.

Method and system for a changing code learning transmitter

Systems, methods, and apparatus for detecting movable barrier disengagement are provided. A movable barrier operator system includes a motor configured to be coupled to a movable barrier and move the movable barrier, a motor sensor configured to measure a load value of the motor, communication circuitry configured to receive, from a remote control, a state change request to cause movement of the movable barrier, and a processor circuit. The processor circuit is configured to cause actuation of the motor in response to receipt of the state change request, detect, based on the load value, a disengagement between the motor and the movable barrier, and cause a communication to be sent, in response to detecting the disengagement, to a remote server, the communication indicative of motor disengagement.

Movable barrier disengagement detection

In one aspect, a movable barrier operator enhancement device is provided that includes communication circuitry configured to transmit a radio frequency control signal to a movable barrier operator and a memory configured to store a first transmitter identification (ID) and a changing code for the radio frequency control signal. The device includes a processor configured to change the first transmitter ID to a second transmitter ID in response to a determination of a transmitter ID change event. The communication circuitry is configured to receive a state change request for the movable barrier operator from a remote computing device. The processor is configured to cause the communication circuitry to transmit a radio frequency control signal including the second transmitter ID to the movable barrier operator in response to the communication circuitry receiving the state change request.
