A Raspberry pi4 is used to run wifi in APN mode, and IOT devices are subbed to this SSID, and packet capture and interrogation are performed on the IOT traffic. Many statistics and plots are derived from the IOT traffic. This "iotsnoop" project also contains the previous project "imonitorg" which is a full, long term monitoring of a user's Internet connection with stats and plots. All stats and plots are available via webpage served by pi4. 802.11g to max range, minimize IOT traffic. ipv4 only. 4GB pi4 recommended for 10 or more IOT plus one streaming device.

Features

  • IOT network monitoring using pi4 wifi in APN mode/eth0 is WAN-side
  • cumulative IOT activity plot
  • IOT device list/DHCP, nonDHCP devices/DNS queries/pkt count/etc
  • Query of individual IOT for last hour web activity
  • Complete packet capture for last hour available as a pcap
  • Plots/stats available via webpage on pi4/standalone/no cloud!
  • All imonitorg functionality included/see imonitorg.com
  • Daily email using gmail relay
  • Restricted to 56Mb/ipv4/802.11g for range/use extender to increase pi4 APN
