I’m trying to get my backyard patio light switch hooked up to my Zen26 switch but there appears to be a curve ball because both of my switches have black wires that go to a bundle. I’ve contacted Zooz support who helped me install all my other switches but they’re not sure how to wire it either.
See attached photos. The triple box is located in the house and the arrow points to the black bundle. The double box is located in an external garage where also the arrow points to the black bundle. Any assistance would be great and would save me $150.
