Spec

Microbit as controller for smart gateway

Relay to turn on/off load

Use led to test load

I used a breakout board from Key-e-Studio to be able to do it with relay attached to microbit and load and used power line to go through relay on microbit breakout board to simulate a real relay but at 5V
