Hi everyone, I am a newbie at this and feel that I am just missing something small. I have a Smarthings hub configured with a camera, door sensor and alarm bell all working fine. Then i purchased some Sonoff R3 basic switches, couldn't see them on smarthings so I loaded eWeLink and it picks them up just fine. I have been through multiple tutorials explaining how to add a virtual switch in Smarthings classic app. Have done this but how do I link that to the eWeLink switch so that I can access it from smarthings?
