Claim 32:
33. A method for use with irrigation devices connected to a multi-wire path in an irrigation system comprising:
providing, by a modulator of the irrigation system, an output power signal modulated with data;
executing, by a control circuit of an irrigation control unit, an automated device discovery process to cause the modulator to modulate the 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 address matches the portion of the address to match; and
providing, by the control circuit via a multi-wire interface, the modulated data over the multi-wire path that extends 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, 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.
