Display Relay Status on NodeRed
#4

Dear Sir.

let me give an example.

If my KC868-H32 relay board is 100meters away and I am in the office. On my NodeRed interface, I have a screen that is showing the Relay buttons. When I click the button 1 it then turn "ON" relay 1. But, how do I know that the relay is actually turned "ON"? 

Is there a way to find out the status of the KC868-H32 relay board to which relay is turned on? 
If I physically walk 100 meters to the relay board controller then I can see the "Red" light where then I know its turned "ON" but walking 100 meters there to verify if the relay 1 is "ON" is un-logic.
Thank You

Regards
Subas
