Techniques are disclosed for managing message redundancy for one or more devices. In one example, a device receives a message from a second device using a transmission protocol, the message comprising a control instruction for an accessory device and a message identifier. The device can transmit using the transmission protocol, a second message to the accessory device, the second message comprising the control instruction and a second message identifier. The device can receive a third message from the second device using a second transmission protocol, the second message comprising a second control instruction for the accessory device and a third message identifier. The device can compare the third message identifier with the message identifier to determine whether the second control instruction is a duplicate of the control instruction. The device can determine whether to transmit the third message to the accessory device based on the comparison.
