Can I use Nucleus without an Internet connection?

You will need an Internet connection to set up and register your Nucleus Anywhere Intercoms, receive software updates, use Alexa, and connect with devices outside of your home network. Each time Nucleus starts up, it checks for an Internet connection to associate with its family and check for updates.

Intercoms on the same network (and the same subnet) will communicate directly with each other, so they will continue to operate if Internet connectivity is temporarily lost and local network connectivity is maintained.
