For me the device is working properly, but only with a resistive load. This means there must be a "light bulb" ca are driven min 40 watts. With LED bulbs and not `s because the load is too low. The load input I constantly under tension, turn and dimme only on the transmitter so that the controller will not boot under load. The unit I ordered on 12.02.2013, it was up to 02.23.2014 every night dimmed in operation. Then a brief flicker and the thyristor was beaten by, at a load of 2x40W. Defective equipment has been withdrawn without objection by Amazon.
