You use the contactor (a very heavy duty relay) to switch the water heater, then you use a smart plug to switch the contactor. Not having an outlet nearby makes things slightly more complex, really just needs an extra fuse to tap off a little power for the smart plug. It would probably be easier to use a "Sonoff Basic" which is designed for hardwired applications. Now you have a networked switch for the water heater with decent software.
