Relay control using Ubidots Dashboard


Hi All,

I want to control relay from ubidots dashboard. I created variable and assigned a switch widget to it. I uploaded following code in NodeMCU.

I do get my device online and the variable also is showing online but when i toggle the switch in ubidots seems doing nothing, i can not see any change of the relay contacts, could anyone help on this context.

Hi there, add this line to your setup() function


For more information, please refer to the library docs.

All the best
