its pretty easy. first, you must create an account at lacrosse alerts. do not register your gw1000u yet. with the lacrosse gateway and the pi plugged in to the same hub (must be a hub, or a switch with port mirroring enabled), do this: if you have never registered the gateway: 0) be sure the gw1000u is powered off 1) on the pi: sudo tcpdump -w /var/tmp/gw1000u-capture-1.pcap -npl -s0 -i eth0 host X.X.X.X and port 80 and http where eth0 is the wired interface for the pi and X.X.X.X is the ip address of the gw1000u if you want to verify that the capture works, use a host of some other computer then visit a web site from that computer. then use wireshark to look at the data. or post it here, if you like. 2) power on the gw1000u follow the instructions at lacrosse alerts for registering your gateway. 3) stop the capture after you see data from the weather station at lacrosse alerts. if you have already registered the gateway: 0) be sure the gateway is powered off 1) on the pi, run the tcpdump command, but use a different file, say capture-gw1000u-2.pcap 2) power on the gw1000u 3) after you see it update two or three times at lacrosse alerts, stop the tcpdump then change your lacrosse passwords and post the pcap files. i'm pretty sure lacrosse gives you one year of full services for free, then after that they charge you for alerts but the basic data collection is 'free'. m -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
