I understand that KS200M is designed for single-pole. I've seen many videos and comments about wiring for 3-way switches though. Is it really possible without concern? What are the drawbacks? i.e. I was going to install two motion switches in our laundry room. One that goes from the main house towards the garage, and the other when entering the house from the garage. They are far enough apart, and around corners, so it makes sense --- if it's possible, and lacks fire hazzard lol.
