First, a Z-Wave network needs to be enabled, but this can be accomplished with a minimum of dollars and effort, because the Z-Wave network, though robust and powerful, is also lightweight, accessible, and highly interoperable.
Next, the “hub” (sold separately) is connected to the network, and then smart devices are added one by one – a smart light dimmer here, a smart thermostat there, a smart water valve in the basement. Suddenly, the devices are reporting to the user – when and if they need attention, and only then. Otherwise, once preferences are set, the devices, including the Z-Wave water valve, go to work, monitoring the safety and comfort of the home – so the homeowner doesn’t have to.
As you add devices to your smart home, remember that the more Z-Wave-enabled devices you have, the stronger your Z-Wave network will be. Z-Wave operates on a mesh network, which means that the more devices you have, the shorter the distance each signal has to travel.
