Claim 33:
34. 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 first data portion and a second data portion, wherein the first data portion corresponds to the portion of the address to match and the second data portion corresponds to feedback periods of time for each of one or more of the irrigation devices to respond,
wherein the first data portion defines a first set of address bits to match and a position of the first set of address bits in the address, and wherein the second data portion defines a set of feedback periods of time, each feedback period of time corresponding to a second set of address bits and a position of the second set of address bits in the address.
