Thereās no need to invest in expensive smart appliances. If you have an old space heater, donāt let go of it just yet! Instead, make it smart by simply plugging it into the device. Then, create a scene to have the heater turn on when the room temperature drops below your desired level. The cherry on top? Youāll always know how much energy youāre consumingāand with Z-Wave Long Range support, the device stays reliably connected even in larger homes.
