I got it to wirelessly control an industrial drum fan. It works to turn the fan off, but because it completely cuts power to the fan (I presume this is the reason), it trips the fan's AC plug reset button (ground fault circuit interrupter?). Therefore to turn the fan back on you must first turn on the SVAT device, then press the fan's reset button. The reset button is not tripped when the fan is plugged directly into the AC outlet.This device may work for some applications, but beware of this limitation. Many outdoor devices have built-in interrupters.I'm currently looking for a competing device that won't trip the reset button.
