Much PIR switch for little money and works perfectly with LED lights

In concept, a great little device, ideal for switching LED lights, as with relay. The 800 Watt are thus never reached to rebut a complaint of some people.
What is missing is a simple plug-in Extension for the sensor, then if it were perfect! To date, 6 of them have built, installed and outdoors partially. Works perfectly despite anderwertiger recommendation. Important is perhaps only the AC adapter and the electronics to build in in a waterproof housing (IP 44 or better).
If the part-reviewed failures not arrive, a great product.
Recommendation: this costs the part little, it pays off reserve units to purchase ... ;-)

Update: already several devices have now installed inside and out with no problems. The winter was the PIR's not touch ... :-)
