Hoping for some advice here. Just bought a Ambient Weather WS-0900 after multiple fruitless attempts to sniff traffic from an Acurite bridge. Thought I was going to have an easy time, but it's turned out to be just as frustrating.

I've downgraded the ObserverIP firmware to 4.2.1, that part was easy. I used setdsthn and the IP of my RPi Zero W running Weewx 3.8.0 and Apache2, then saved the firmware config and rebooted the ObserverIP. Changed the port Apache is using to avoid a conflict. I've tried both Matthew Wall's weewx-interceptor and Pat O'Brien's socketlogger, but I get no data in Weewx. I even had someone send me a preconfigured Pi image. He has an Aercus with the same bridge (granted different firmware with the custom option to set a server), but it also doesn't work for me. So I think I must not be getting output from the bridge, but how do I test this?

I really want to avoid using a router to forward. I have four routers on my network as it is. That's enough.
Any advice would be appreciated. I really am at my wits end trying to make Weewx work with this second weather station. My hope is to own the weather data and locally direct it to my home automation hub which also doesn't rely on the cloud, but I'm discouraged at this point.

I can only tell you how mine is hooked up.  I have a linux box (pi) running weewx and the accurite 5 in 1 usb connection.  The computer is hooked wirelessly.  I then use the csv plugin and drop the file onto dropbox.
My computer (windows) in my office is also connected to dropbox and so I use two programs I wrote in vb.net.  One cleans the data and writes the clean data to another csv file.  The second takes the clean data and uses it for prediction.

Thanks for the reply John. I was close to just getting the USB 5 in 1 because it seems to be the path of least resistance. Kind of thought I wan't going to have as much trouble with the Ambient Weather ObserverIP bridge, but here I am again! The fact that after only a year of ownership of the original Acurite bridge, they were going to cut me off next month and now they're going to kill the service to it in February, I wasn't too keen to spend more money with them. I really like the services offered from Ambient Weather, and they have a nice free dashboard that is mobile friendly.

While your setup doesn't exactly relate to what I'm hoping for, it's maybe something I could revisit the concept if I can't get what I prefer working. I had been looking around and weathercloud.net is a possible choice to export csv files. Only I would still need to get my data there, and it's cloud based, which I'm trying to avoid.

The key is to get the WiFi adapter into monitor mode. I do this by having a USB WiFi adapter and use it as an AP, but I believe that you can sniff or monitor the data without setting up an AP. The AP is just simpler IMO.
Not running on a Pi, I have a linux server that I added the AP to after a test install on a small Atom powered box.

Can you elaborate on "the WiFi adapter" you're talking about? I don't have the USB 5 in 1 version. Is that what you are referring to? I have the ObserverIP bridge that receives the 915 MHz signal from my station components and converts it to IP over an ethernet connection. I have no display panel with my Ambient Weather WS-0900-IP.

A USB WiFi adapter.
But, if you have 4 routers available, use one of them if they are Tomato or Asuswrt-Merlin compatible.

I just look out the window  for the local weather. DO NOT CONTACT ME FURTHER.

Thanks everyone for the assistance. I have this working now using a router with instructions from Pat O'Brien https://obrienlabs.net/redirecting-weather-station-data-from-observerip/ and the weewx-interceptor module from Matthew Wall.

One thing this doesn't do is allow me to continue to upload to Ambientweather.net and capture the data on port 80 from WU to forward to my Apache2 server. Anyone know how to do both? Assuming it would be an addition to the DD-WRT firewall, but I've no idea how to do that.
