Good question, but an easy answer: It doesn’t matter as long as you do a Z wave repair and a zigbee heal after all of the devices are in place. That will update all of the neighbor tables so every device knows their most efficient routing.
I just suggested to you in one of your other threads that you read the wireless range FAQ as it will answer many of your basic questions. I’m going to include that here again just for others who might find this topic in the future. (This is a clickable link)
Start with post 11 in that thread and read it, then go back up to the top of the thread and read the full FAQ
