wu_client with wifi console #81

Closed wrvolz closed 3 years ago

wrvolz commented 3 years ago

I have a WS-2002 which looks like a Fine Offset HP2550. The console is talking to WU with no problem. I'm running weewx on a raspberry. I'm trying to use wu_client to get the data. I also have an Apache server running on port 80. The Raspberry is at IP x.y.0.3 on eth0. The Console is at IP x.y.0.197. I can ping the console from the RPI. I tried Interceptor parameters but I'm getting nothing. The last few lines of the /var/log/messages are: Sep 14 21:32:13 raspberrypi weewx[10453] INFO weewx.engine: Loading station type Interceptor (user.interceptor) Sep 14 21:32:13 raspberrypi weewxd: interceptor: MainThread: driver version is 0.46 Sep 14 21:32:13 raspberrypi weewxd: interceptor: MainThread: device type: wu-client Sep 14 21:32:13 raspberrypi weewxd: interceptor: MainThread: sensor map: None Sep 14 21:32:13 raspberrypi weewxd: interceptor: MainThread: mode is sniff Sep 14 21:32:13 raspberrypi weewxd: interceptor: MainThread: sniff iface=eth0 promiscuous=0 Sep 14 21:32:13 raspberrypi weewxd: interceptor: MainThread: sniff filter 'src 192.168.0.197 and dst port 80'

What do I need to change to get this working? Also, once it's working will need to have weewx upload the record to WU? Thanks,

Update - I though pypcap was installed - it wasn't. After installing that I got this: Sep 14 22:03:46 raspberrypi weewxd: interceptor: MainThread: sniff filter 'src 192.168.0.197 and dst port 80' Sep 14 22:03:46 raspberrypi weewx[11938] ERROR weewx.engine: Import of driver failed: in method 'pcapObject_open_live', argument 2 of type 'char *' (<type 'exceptions.TypeError'>) Sep 14 22:03:46 raspberrypi weewx[11938] CRITICAL weewx.engine: Traceback (most recent call last): Sep 14 22:03:46 raspberrypi weewx[11938] CRITICAL weewx.engine: File "/usr/share/weewx/weewx/engine.py", line 103, in setupStation Sep 14 22:03:46 raspberrypi weewx[11938] CRITICAL weewx.engine: self.console = loader_function(config_dict, self) Sep 14 22:03:46 raspberrypi weewx[11938] CRITICAL weewx.engine: File "/usr/share/weewx/user/interceptor.py", line 225, in loader Sep 14 22:03:46 raspberrypi weewx[11938] CRITICAL weewx.engine: ** return InterceptorDriver(config_dict[DRIVER_NAME]) Sep 14 22:03:46 raspberrypi weewx[11938] CRITICAL weewx.engine: File "/usr/share/weewx/user/interceptor.py", line 2208, in init Sep 14 22:03:46 raspberrypi weewx[11938] CRITICAL weewx.engine: self._device = self.DEVICE_TYPES.get(self._device_type)(stn_dict) Sep 14 22:03:46 raspberrypi weewx[11938] CRITICAL weewx.engine: ** File "/usr/share/weewx/user/interceptor.py", line 584, in init Sep 14 22:03:46 raspberrypi weewx[11938] CRITICAL weewx.engine: ** WUClient.Parser(), handler=WUClient.Handler, stn_dict) Sep 14 22:03:46 raspberrypi weewx[11938] CRITICAL weewx.engine: File "/usr/share/weewx/user/interceptor.py", line 283, in init Sep 14 22:03:46 raspberrypi weewx[11938] CRITICAL weewx.engine: iface, pcap_filter, promiscuous) Sep 14 22:03:46 raspberrypi weewx[11938] CRITICAL weewx.engine: File "/usr/share/weewx/user/interceptor.py", line 325, in init Sep 14 22:03:46 raspberrypi weewx[11938] CRITICAL weewx.engine: self.sniffer.open_live(iface, snaplen, pval, timeout_ms) Sep 14 22:03:46 raspberrypi weewx[11938] CRITICAL weewx.engine: File "/usr/lib/python2.7/dist-packages/pcap.py", line 108, in open_live Sep 14 22:03:46 raspberrypi weewx[11938] CRITICAL weewx.engine: def open_live(self, args): return _pcap.pcapObject_open_live(self, args) Sep 14 22:03:46 raspberrypi weewx[11938] CRITICAL weewx.engine: TypeError: in method 'pcapObject_open_live', argument 2 of type 'char ' Sep 14 22:03:46 raspberrypi weewx[11938] CRITICAL main: Unable to load driver: in method 'pcapObject_open_live', argument 2 of type 'char ' Sep 14 22:03:46 raspberrypi weewx[11938] CRITICAL main: Waiting 60 seconds then retrying...

Found a solution. Uninstall python-libpcap and install python-pypcap. Now to figure out how to forward the packet to weewx.
