Hi, I am looking for a smart system to control the light of 3 rooms, but I am not sure I am in the right direction.We have 3 rooms need to control the light via app(anywhere), but we also wish to have separate motion detecters to turn on/off the light if possible. It looks like Caseta can done it, right? Bridge + 3 motion + 3 smart switch are all I need?Thank you very much.Li
