Relaying communications in a wireless sensor system

A wireless repeater device comprising:

• a wireless transceiver configured to receive a communication packet including an address portion that comprises a first code, a second code, a checksum, and an authenticity code for use in verifying an authenticity of the communication packet;
• and
• a controller, comprising a table of wireless sensor identifiers, the controller configured to:
• determine if the first code in the communication packet corresponds to a building code associated with the wireless repeater device;
• based on the determination that the first code corresponds to the building code associated with the wireless repeater device, compare the second code to the wireless sensor identifiers in the table;
• and
• based on the second code matching to a wireless sensor identifier in the table, relay the communication packet using the wireless transceiver.

A wireless sensor system comprising:

• a wireless repeater unit comprising a table of wireless sensor identifiers, the wireless repeater unit configured to:
• receive a communication packet including an address portion that comprises a first code, a second code, a checksum, and an authenticity code for use in verifying an authenticity of the communication packet;
• determine if the first code in the communication packet corresponds to a building code associated with the wireless sensor system;
• based on the determination that the first code corresponds to the building code associated with the wireless sensor system, compare the second code to the wireless sensor identifiers in the table;
• and
• based on the comparison matching the second code to a wireless sensor identifier in the table, relay the communication packet.
