I am using the interceptor extension for my Ambient Weather WS-2902. Data sent to wunderground, ambientweather.net, and weathercloud are the same as on my console. The data sent through weewx is way off. I.E., temperature is off by 12 degrees.
I installed weewx in the simulator mode. *Here is the relevant sections in my weewx.conf* ############################################################################## [Simulator] # This section is for the weewx weather station simulator # The time (in seconds) between LOOP packets. loop_interval = 2.5 # The simulator mode can be either 'simulator' or 'generator'. # Real-time simulator. Sleep between each LOOP packet. mode = simulator # Generator. Emit LOOP packets as fast as possible (useful for testing). #mode = generator # The start time. Format is YYYY-mm-ddTHH:MM. If not specified, the default # is to use the present time. #start = 2011-01-01T00:00 # The driver to use: driver = weewx.drivers.simulator ############################################################################## [Interceptor # This section is for the network traffic interceptor driver. # The driver to use: driver = user.interceptor # Specify the hardware device to capture. Options include: # acurite-bridge - acurite internet bridge # observer - fine offset WH2600/HP1000/HP1003, aka 'observer' # lw30x - oregon scientific LW301/LW302 # lacrosse-bridge - lacrosse GW1000U/C84612 internet bridge device_type = observer # mode = sniff # iface = eth1 # pcap_filter = src 192.168.0.25 and dst port 80 (Note: this the IP of my console – but don’t see anything with tcpdump) *Here is the uploading section from my syslog file:* Mar 17 10:05:15 freyr weewx[23744]: manager: Added record 2018-03-17 10:05:16 PDT (1521306316) to database 'cmon.sdb' Mar 17 10:05:15
