I’m new to Smartthings, and I’m struggling with multiple switch control. I have 2 z-wave switches controlling lights in my family room. I want to be able to control them both together and separately. I created a virtual switch, and I’m using a smart app (smart lighting) to control the 2 switches. It works, but if one of the switches is already on, it won’t shut off from the virtual switch. It’s as if the virtual switch doesn’t know it’s on, and therefore won’t send the off signal.
I found and tried to install The Big Switch using IDE, but I can’t locate it from the Smart App. I’m lost and could use some help.
