ECHONET Lite パケットレコーダー egREC
Captures ECHONET Lite packets and uploads PCAP to Google Drive (or USB) for remote analysis with Wireshark.
egREC captures ECHONET Lite traffic—typically UDP to port 3610—between a home-energy controller and field devices, then packages it as gzip-compressed PCAP on an hourly cadence for upload to Google Drive (or retention on USB flash when you prefer).
The edge stays PC-less: power and network are enough at the site, while analysts pull captures from Drive and open them in Wireshark. Shared folders make it practical for partner companies to see the same timeline without shuttling media.
Your network must provide DHCP, internet reachability, DNS (the product is validated with 8.8.8.8), and NTP so timestamps stay trustworthy. For integrators who need defensible, shareable evidence of on-site ECHONET behavior, egREC matches the workflow described on bitset.jp. Purchase is via direct inquiry to bitset.
