Hi! Im in a new appartment and I want to introduce my self into the home automation world. I just bought the ST hub, and now Im buying accesories. I have found one problem: All of my light switches has 2 or three buttons, and controls 2 or 3 different lights respectevely independently. All I have seen are single button Zwave switchs. Is there any that can control 3 or 2 lights? Or I have to buy 3 independent switches?
