Relay sensors stop communicating with gateway after a few minutes

I thought the same, it was how i detected i had 12v relays instead of 5v. I just quickly powered with 9v bat and then the relay clicked.

Thanks for the heads up. But I tried 9v and 12v and no luck! They only click when powered directly from the Arduino and they stop working after a few hours.

This is how I have my connections:
Is there anything wrong with it?
Thanks! -
Try adding a wire between the GND on your relay board and GND on your arduino. Even if they have seperate power source you stil need to connect GND between them.

YES!!! That was it! I got both relays powered from the external power supply now and everything seems to be working fine.
Thank you all very much!
