  • PLUG, PLUG & PLAY! Take advantage of direct ethernet connection and be online almost instantly when you plug your Hub into your router or network switch. Or, use hot spot mode to connect to your WiFi network in moments. Add devices in seconds using our Scan & Play QR code scanner in the app! Set your notification preferences, test your new sensors, then enjoy years of trouble-free operation!
  • KNOW NOW! You have many options for being notified of device activity! Receive a text, receive an email, receive a phone push notification (including Apple phone "Critical Alert" severe weather/Amber alert type notifications that will activate your phone even if in silent mode.
