I don't know who designed my kitchen but putting light switches on opposite sides was just plain silly. I have two GE Z-Wave plus switches for my counter and table lights. They used to be associated when on my Vera Plus but moving them over to Hubitat I lost the association. And frankly, the process to associate them on Hubitat is beyond my skill set.
So why not use Mirror Me? Works well and the one thing I can do that I couldn't do through associations is control dimming of both circuits. I am sure I could have used a Simple Lighting rule but thought this an interesting use of the App.
