Systems, methods, and apparatuses for one-way communications are disclosed. A system includes a transmitter, a first receiver, and a second receiver. A transmitter transmits one or more messages on one or more channels according to a predetermined, pseudo-random channel hopping protocol. The receivers receive said transmissions according to the order of the pseudo-random channel hopping protocol. Methods for re-syncing the one-way system in the event of a power loss or other event causing desynchronization. Default waiting channels are established for the receivers once a certain number of channel detection periods according to the one-way communication protocol result in no detected signals.
