This adapter plugs was very cheap (30 euros the cheapest). For this he is quite pretty (reflective front) and apparently to control via WLAN also.
What I found exciting: My Z-Wave home network recognized the part within one second after it in "learning mode" was (to enable this, a second on button press).
What I found even better: Many components react. Then, the control software or the user never knows but the current Satus - is off or on? THIS adapter plug is back, which for example, the Z-Way software always to know the state and this also indicates accurately.
Also nice: The part also serves as a Z-Wave "repeater", ie you hereby extended the reach of its Z-Wave network. Great feature for a low-priced device!
Have only one question .. I have since incorporated them, is my display also a temperature - but always the same apparently: P Does the part a temperature sensor in there ?!
