1. A landscape system to selectively power and activate devices along two-wire communication networks using data encoded power waveforms, the landscape system comprising:
a landscape controller comprising:
a processor configured to generate a control signal responsive to user information, the control signal having a first state and a second state;
a power supply configured to receive an input power signal and provide an AC power signal;
first driver circuitry configured to receive the control signal and the AC power signal, and output the data encoded waveforms, the first driver circuitry communicating with the processor to receive the control signal, pass the AC power signal in-phase when the control signal is in the first state and shift a invert the phase of the AC power signal when the control signal is in the second state; and
second driver circuitry configured to receive the control signal and the AC power signal, and output the data encoded waveforms, the first driver circuitry communicating with the processor to receive the control signal, pass the AC power signal in-phase when the control signal is in the first state and shift a invert the phase of the AC power signal when the control signal is in the second state;
a first two-wire communication network in communication with the landscape controller to receive the data encoded power waveform from the first driver circuitry;
a second two-wire communication network in communication with the landscape controller to receive the data encoded power waveform from the second driver circuitry;
at least one first decoder in communication with the first two-wire network and at least one first device, the at least one first decoder addressable over the first two-wire communication network and configured to receive the data encoded waveform and control the at least one first device in response to the data encoded power waveform; and
at least one second decoder in communication with the second two-wire network and at least one second device, the at least one second decoder addressable over the second two-wire communication network and configured to receive the data encoded waveform and control the at least one second device in response to the data encoded power waveform.
