WiFi and internet access are distinct concepts. "Off-grid" networks allow devices to communicate via WiFi without internet connectivity, offering inherent security through isolation from external networks. A common example is WiFi-enabled printers functioning on local networks.
To create an off-grid network using #dot devices:
  1. Activate the first #dot (purple LED indicates no router connection)
  2. Power on a second #dot (blue LED signifies connection to the root node)
  3. Connect your smartphone to the "#dotdot" WiFi network: iOS or Android, it will indicate that this network has no internet access, which is precisely what is sought for with off-grid networks.
This configuration enables isolated local communication between devices. Specialized applications designed for off-grid functionality are available on app stores. Acquire #dot devices and the #dotdot app to establish your own secure, local network.
