Switching iPhones, or any phone!

I have my wife setup on SmartThings so that when she (her phone) leaves our house, the system gets a notification. Now she has changed phones, and I can’t work out how to update these settings for her new phone. Any help is greatly received.

Thanks

You’ll need to install the SmartThings app on her new phone, then open it and add that phone as a presence indicator. Then you should be all set. (I suspect this is a security feature to prevent stalking, but in any case, you have to give permission from that phone.)
