Our Nest thermostats needs to be setup once. When you want to control it using another mobile device, all you need to do it is to login on the Nest app of the new pone using the same email address and password that is working on the other mobile device.
I haven't heard from you in a while so I'll be locking this thread if there is no update within the day. Should you have any new issues, updates or just a discussion topic, feel free to start a new thread in the community.
