I'm sorry for the delay and trouble. Let's see what's going on — are you able to download the Nest app on your phone? If so, whats the exact message are you getting when setting up your Nest Protect? Check out this link on how to Set up Nest Protect with the app.
@MarcV that's good to hear and thanks for getting back to us. Please let me know if you have other questions or concerns as I will be locking this after 24 hours. Feel free to start a new thread and we'll be happy to help.
I appreciate the help, Archie.
