1. An irrigation control unit for use with irrigation devices connected to a multi-wire path in an irrigation system comprising:
a modulator configured to provide an output power signal modulated with data;
a multi-wire interface coupled to the modulator and configured to electrically couple to the multi-wire path extending into a landscape and to which the irrigation devices are connected, the irrigation devices each having a unique address and configured to derive operational power from the output power signal and demodulate the data; and
a control circuit coupled to the modulator and configured to execute an automated device discovery process configured to:
cause the modulator to modulate data comprising a discovery message on the output power signal, the discovery message indicating a portion of an address to match and prompting a response from one or more of the irrigation devices in which a corresponding portion of the unique address matches the portion of the address to match,

wherein the discovery message comprises a data portion defining a number of address bits in the portion of the address to match and defining a value of the address bits of the portion of the address to match.
