My Migration from IRIS

Welcome! :sunglasses: You don’t need to use only the ADT/SmartThings to dual logo sensors with the ADT system. It’s just those are the only ones that can trigger a call to the ADT monitoring center.

You can use all of your other devices, including many of your former iris devices, with the ADT/SmartThings Hub For your home automation rules, such as having a motion sensor trigger a light to turn on, or getting a notification if your garage door was left open.

So it just comes down to exactly what you are trying to do as to how many new devices you might need to buy. :sunglasses:
