+=== Communication ===
 The ezeio connects to the Internet via Cellular or Ethernet. A cellular modem is built in to the unit, but an external antenna is required. By default, if there is an Ethernet connection that allows Internet access, //Ethernet is prioritized//. If for any reason the Ethernet connection is not available, the ezeio will automatically switch to use the cellular connection. If the Ethernet becomes available after the cellular connection has been established, the ezeio will switch to the Ethernet after a few seconds.
