In one implementation, an irrigation control system includes a transmitter unit including a controller and a connector to be coupled to an irrigation controller having station actuation output connectors. The controller is can receive an indication that the irrigation controller has activated an irrigation station, and can cause the transmitter unit to transmit a wireless activation signal responsive to the indication. A receiver unit is coupled to an actuator coupled to an actuatable device, such as an irrigation valve, the actuator configured to actuate the irrigation valve to control the flow of water therethrough. The receiver unit receives the wireless activation signal and in response, causes the actuator to actuate the actuatable device. ## Claims ### Claim 1 A method for use in controlling irrigation comprising: executing, by an irrigation controller, an irrigation schedule defining watering days, start times and watering durations for one or more stations; outputting, by the irrigation controller, a control signal corresponding to the execution of the irrigation schedule indicating that a first irrigation station of a plurality of irrigation stations is to be activated; receiving, at a transmitter unit coupled to the irrigation controller, an indication that the irrigation controller has activated the first irrigation station, wherein the transmitter unit is programmed such that the first irrigation station of the plurality of irrigation stations is associated with a first one or more wireless receiver units located remotely from the transmitter unit, and programmed such that a second irrigation station of the plurality of irrigation stations is associated with a second one or more wireless receiver units located remotely from the transmitter unit; and transmitting, by the transmitter unit and responsive to the indication, a wireless activation signal, configured for receipt at the first one or more wireless receiver units, wherein each of the first one or more wireless receiver units is coupled to an actuator and an actuatable device. ### Claim 2 (depends on 1) The method of claim 1 wherein the actuatable device comprises an irrigation valve controlling the flow of water therethrough. ### Claim 3 (depends on 1) The method of claim 1 wherein the transmitter unit comprises a connector comprising a power connection configured to be coupled to the irrigation controller to receive operational power. ### Claim 4 (depends on 1) The method of claim 1 wherein the irrigation controller is contained within a first housing and the transmitter unit is contained within a second housing separate from the first housing. ### Claim 5 (depends on 1) The method of claim 1 further comprising: receiving, at a signal receiver of one of the first one or more wireless receiver units, the wireless activation signal from the transmitter unit; receiving, at a first controller coupled to the signal receiver, a message contained in the wireless activation signal; and causing, responsive to the message, an activation circuit coupled to the first controller to output signaling; and causing, responsive to the output signaling, the actuator to actuate the actuatable device. ### Claim 6 (depends on 5) The method of claim 5 wherein the actuatable device comprises an irrigation valve controlling the flow of water therethrough. ### Claim 7 (depends on 5) The method of claim 5 further comprising: receiving the wireless activation signal at one or more additional wireless receiver units of the first one or more wireless receiver units, each configured to be coupled to an additional actuator coupled to an additional actuatable device, the additional actuator configured to actuate the additional actuatable device; and causing, at each of the one or more additional wireless receiver units and in response to the receiving, the additional actuator to actuate the additional actuatable device. ### Claim 8 (depends on 1) The method of claim 1 wherein the transmitter unit comprises a connector coupled to the irrigation controller, wherein the connector comprises an input connector configured to be coupled by wireline to an output connector of the irrigation controller. ### Claim 9 (depends on 1) The method of claim 1 wherein the transmitter unit comprises a connector coupled to the irrigation controller, wherein the connector comprises an input connector configured to be coupled to one or more station actuation output connectors of the irrigation controller. ### Claim 10 (depends on 1) The method of claim 1, wherein the transmitter unit has a user interface comprising one or more user inputs. ### Claim 11 (depends on 10) The method of claim 10 wherein the one or more user inputs comprise one or more buttons. ### Claim 12 (depends on 10) The method of claim 10 further comprising changing an operational state of the transmitter unit when the one or more user inputs are manipulated by a user. ### Claim 13 (depends on 10) The method of claim 10 wherein the user interface further comprises a display screen. ### Claim 14 (depends on 1) The method of claim 1, wherein the transmitter unit is a module detachably coupled to the irrigation controller. ### Claim 15 (depends on 1) The method of claim 1, further comprising receiving, at the irrigation controller, a signal from a second irrigation controller causing the irrigation controller to activate the first irrigation station. ### Claim 16 (depends on 15) The method of claim 15, wherein the second irrigation controller comprises a handheld controller. ### Claim 17 (depends on 15) The method of claim 15, wherein the second irrigation controller comprises a central controller. ### Claim 18 A method for use in controlling irrigation comprising: coupling a transmitter unit with an irrigation controller, wherein the transmitter unit is a module detachably coupled to the irrigation controller; receiving, at a first controller of the transmitter unit through a connector configured to be coupled to the irrigation controller, an indication that an irrigation controller has activated an irrigation station; receiving, at the first controller through a user interface comprising at least one user input of the transmitter unit, at least one user input, wherein the transmitter unit is programmed such that a first irrigation station of a plurality of irrigation stations is associated with a first one or more wireless receiver units located remotely from the transmitter unit, and programmed such that a second irrigation station of the plurality of irrigation stations is associated with a second one or more wireless receiver units located remotely from the transmitter unit; and transmitting, by the transmitter unit and responsive to the indication, wireless activation signal configured to be received by a first one or more wireless receiver units, wherein each of the first one or more wireless receiver units is coupled to an actuator and an actuatable device, the actuator configured to actuate the actuatable device, the first one or more wireless receiver units each configured to cause the actuator to actuate a corresponding irrigation valve in response to receiving the wireless activation signal. ### Claim 19 (depends on 18) The method of claim 18 wherein the at least one user input is received at the first controller via a user interface comprising a display screen. ### Claim 20 (depends on 18) The method of claim 18, further comprising receiving, at the irrigation controller, a signal from a second irrigation controller causing the irrigation controller to activate the irrigation station, wherein the second irrigation controller comprises a central controller and a handheld controller.
