12V 433Mhz switch
Hi guys,
I bought this item: http://www.ebay.de/itm/433Mhz-Wireless-Remote-Control-1CH-Relay-Switch-Transceiver-Receiver-12V-HS736-/142259756211
But unfortunately I dont know how to wire it. Could anybody help?
The remote control works well as pir6.
In the screw terminal with the two inputs you have to put the 12v supply voltage. I think you have to look to + and -.
In the screw terminal with the three outputs (it is from the relay) one is the base, one is normally closed and one is normally opened.
You can test what what is with a circuit indicator.
Two of the three terminals are labeled with L- and N+
All other holes have no label.
What should I measure to find VCC and Ground?
I already played around with my multimeter but I wasn’t able to find a solution.
I have a 12V power supply and a 12V light. How should I wire the four corresponding cables?
No, I think the terminal with three holes are outputs and no inputs.
I’ll test it today.
another nice way for a relais device is ESPimatic in connection with an relais pcb.
i use two of these devices actually and switch 4 and 2 relais with it. works like a charm.
pimatic v0.9 has been released!

@Heizelmann said in 12V 433Mhz switch:
Look here for a curcuit diagram. It tells something different than @V1per telled above.
You are right, I have just guess and have no circuit diagram.
It is strange that you have a connector with three inputs where you use only two.
And on the side from the relay only two. So the relay can only work at closer.
The device does not work at all 
I already got my money back and ordered two other ones.
