Bradford White Water Heater Thermostat

Does anyone know if there is a way to control the thermostat on a Bradford White Water Heater with accessory module via some z-wave device? Or if possible to replace the thermostat with a typical heater z-wave thermostat? As far as I know, water heater thermostat runs at much higher temperature, so a typical air vent heater thermostat may not work.

Advise please. I would like to be able to control the temp, turn on or off the water heater remotely.

There’s this thing: http://www.gaswaterheatertimer.com/wireless-home-automation

However, it won’t work with my Bradford White water heater, as it doesn’t interface with the thermostat on mine.
