First, I would like to say thank you for the assistance. I have referred to this forum many times for assistance, and have always found the answers to my questions by reading through the threads.
I have been using two Schlage door locks and two Honeywell z-wave thermostats for about a year now, and would like to start expanding my ST network. The next think I would like to di is my hall lights. I have a hall light setup that has two light fixtures and three switches. Can I replace only one of the switches with a smart switch, and leave the other switches as standard light switches, or do I have to replace all three switches?
