1. Apparatus comprising:
a control system configured to control at least one of water flow and water properties in a system that is operative to deliver water from a water source to a water network including a plurality of water use devices,
including
a master controller,
a plurality of slave controllers, wherein at least some of the slave controllers are disposed away from the master controller,
wherein the master controller includes at least one processor in operative connection with at least one data store, and a master transceiver that enables the master controller to communicate with each of the slave controllers,
wherein each slave controller includes at least one processor in operative connection with at least one data store and a respective slave transceiver that enables the respective slave controller to communicate with the master controller,
an electric water heater, wherein the water heater is selectively operative to heat water received from the water source responsive to electrical power delivered to the water heater,
an electric relay, wherein the electric relay is in operative connection with the water heater and is selectively operative to cause electricity from an electrical power source to be delivered to the water heater or withheld from the water heater,
a water heater relay slave controller in operative connection with the electric relay,
at least one sensor, wherein the at least one sensor is operative to sense at least one property of at least one of the electrical power source and the water heater,
wherein the master controller is operable to
determine responsive at least in part to the at least one sensor, a condition of at least one of the electrical power source and the water heater,
responsive at least in part to the determined condition, communicate with the water heater relay slave controller,
wherein the communication between the master controller and the water heater relay slave controller is operative to cause the water heater relay slave controller to cause the electric relay to deliver electrical power to or withhold electrical power from the water heater.
