Quite often you will find yourself in a situation where you would like to have the ability where you want to want to use one button to toggle another device between ON and OFF states. The best way to operate a device with 1 button on another device is to use scenes but you will see scenes don’t have a toggle feature (at least at the moment of writing this tutorial at October 23rd, 2020 and eWeLink 4.6.0). How do you solve that issue?

With thanks to the community we created this tutorial. Special thanks to Anuar Ahmad who shared his idea and screenshots on Facebook and allowed us to use his text and images.

This tutorial assumes the button to control the other device with is a RF button. This could be Zigbee button too.
