Message redundancy between user devices

A first device, comprising:

• a processor;
• and
• a computer-readable medium including instructions that, when executed by the processor, cause the processor to perform operations comprising:
• receiving a first message from a second device using a first transmission protocol, the first message comprising a first control instruction for an accessory device and a first message identifier,
• wherein the accessory device is separate from the first device,
• wherein the first control instruction provides instructions to control the accessory device;
• transmitting, using the first transmission protocol, a second message to the accessory device, the second message comprising the first control instruction and a second message identifier;
• receiving 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;
• comparing the third message identifier with the first message identifier to determine whether the second control instruction is a duplicate of the first control instruction;
• and
• determining whether to transmit the second message to the accessory device based at least in part on the comparison of the third message identifier with the first message identifier.

A non-transitory computer-readable medium including stored thereon a sequence of instructions that, when executed by a processor, causes the processor to perform operations comprising:

• receiving, by a first device, a first message from a second device using a first transmission protocol, the first message comprising a first control instruction for an accessory device and a first message identifier,
• wherein the accessory device is separate from the first device,
• wherein the first control instruction provides instructions to control the accessory device;
• transmitting, using the first transmission protocol, a second message to the accessory device, the second message comprising the first control instruction and a second message identifier;
• receiving 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;
• comparing the third message identifier with the first message identifier to determine whether the second control instruction is a duplicate of the first control instruction;
• and
• determining whether to transmit the second message to the accessory device based at least in part on the comparison of the third message identifier with the first message identifier.
