> You will probably know the answer. When the hub is offline. How do the devices know which repeater to go to and which mesh to build? Don’t they need to know the location of the hub first?

They won’t start rebuilding until the hub comes back online. 🕶 Once the hub comes back online, all the devices come out of panic mode but they understand that something has happened so that’s when they rebuild their neighbor tables.
