Hello Rainer, I've used this instruction, as I can remember, to set up the RPi as an AP (repeater).
https://raspberrypi.stackexchange.com/questions/89803/access-point-as-wifi-router-repeater-optional-with-bridge/89804#89804 There are other instructions too, but none of the others was working for me. As I used a RPi Zero W, I've set up the device as a repeater, but if you used a RPi 3 or something which has eth connector, it is another story, because you can create and AP with the Wifi, and pass all data packets to the ethernet. With the RPi Zero W, it is an AP/Client setup. In my setup all the data what passes through the RPi is sniffed by the interceptor, and it is passed to WU without modification. So, what you want that would work. Otherwise, if you set up WeeWX and interceptor, just to intercept/receive, then you can configure WeeWX to send the collected data to WU too, or any other web-service what is listed in the config, please see the wiki for that, if you need it. Interceptor in sniffer more: >From the interceptor.py ( https://github.com/matthewwall/weewx-interceptor/blob/master/bin/user/interceptor.py ) SniffServer vs TCPServer The driver can obtain packets by sniffing network traffic using pcap, or by listening for TCP/IP requests. The pcap approach requires the python pypcap module, which in turn requires libpcap. This means a separate installation on most platforms. https://github.com/pynetwork/pypcap To run a listener, specify an address and port. This is the default mode. For example: [Interceptor] mode = listen address = localhost port = 9999 To run a sniffer, specify an interface and filter. For example: [Interceptor] mode = sniff iface = eth0 pcap_filter = src host 192.168.1.5 && dst port 80 """ My weewx config looks like this for interceptor: [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, smarthub, or access # observer - fine offset WH2600/HP1000/HP1003, ambient WS2902 # lw30x - oregon scientific LW301/LW302 # lacrosse-bridge - lacrosse GW1000U/C84612 internet bridge # wu-client - any hardware that uses the weather underground protocol device_type = wu-client mode = sniff iface = ap0 pcap_filter = src 192.168.6.5 and dst port 80 In my case ap0 is the name of the network interface, and the weather station's console is 192.168.6.5, defined in the dnsmasq as I remember. There are two/three issues what I have seen with my setup. Rain is not logged correctly by weewx, but I think is mostly due to the RPi Zero W's speed capabilities. But I tried to fix for myself the interceptor.py. Due to my Wifi network, and equipment, I have Wifi dropouts, which causes some issues by the AP (repeater) setup, I have a script added to chron to restart the Wifi connection and the AP, if something goes wrong. It has happened twice so far, that Interceptor stopped sniffing, probably due to the previous issue and Wifi and AP restart. I might add another chron job later to restart weewx every X days or something. But the good thing, if the interceptor is not sniffing the packets are still passed through and reaches WU. I hope this helps! Let me know if you need any other info.
