Dimmer loses his memory

"Does exactly what it should!" ...?
I can unfortunately not connect my speakers throughout.
For me, it takes between 15 min. And max. 2 days: at some point, he loses his memory (switching state, dimming level) and falls in its Grundeinstelllung back: off.
It was previously also twice that while he was at, without any action suddenly went out, so the light went out.
I suspect that the dimmer VLT. is brought out of time by voltage spikes. Since the manufacturer must therefore clearly rectify !! (I hope he reads this!)
Replacing dimmer Amazon had the same exact problem! So by design.

In general, it is regrettable that the dimmer is turned on as a default value (when the voltage is applied), but - as I said - is OFF!
So if you want other him from an ordinary wall switch on / off (the remote control (here AB-440K) used only for dimming), it is necessary that it is supplied with continuous voltage. It is thus for example unfortunately not possible to operate it with only the two, located on the ceiling wires (because one of them is indeed connected with the wall switch: no continuous voltage).!
Therefore, it is always necessary for it, extra to draw a separate, third line. Very bad! This circumstance would have been really easily avoidable !! ...
Thus, since the developer has not really thought along! ... I hope he reads this! ...

Otherwise, the dimmer works fine (tested with 60 W). Because of the shortcomings therefore a star deduction!
