Weewx running but interceptor not capturing data?

[Mark Sanchez]

Hello,

I have now wasted four days so far trying to get weewx setup with my Ambient WS-2902 using interceptor to sniff the packets as it's headed to Ambient Weather's site. I believe I have it running at this point and Apache is set up but nothing is going into the specified folder. How can I tell if it's sniffing the data or not?

I have changed my iptables to capture the local IP and port but it doesn't seem to be doing anything. Any ideas or any more information I could add?

Thanks.

In the absence of you providing any config file(s) nor debug=1 logs nope no ideas other than trying dropping shields and running with no firewall if you can do that safely on your network.

[Rainer Lang]

you may have to have your console post its data also via the customized server functionality to your RPi, using Wunderground protocol, and e.g. port 8000
and then have your interceptor driver at the weewx end listen at port 8000. Mode would then be listening and not sniffing ! wu-client to be chosen as device
(weewx.conf [Interceptor] stanza)
You can also first try to run the driver stand-alone as described in the READ.ME on GitHub

I have turned off the firewall in ufw to see if it was any port closures that were causing issues. I also opened port 80 on the weather station in my router.

Here's how my conf file is set up:

# Set to 1 for extra debug info, otherwise comment it out or set to zero
debug = 0

# Root directory of the weewx data file hierarchy for this station
WEEWX_ROOT = /

log_success = True

# Whether to log unsuccessful operations. May get overridden below.
log_failure = True

# Do not modify this. It is used when installing and updating weewx.
version = 4.10.2

I actually restarted and am getting something where the interceptor is finally being pinged but it's showing this in the syslog:

So it's acknowledging the interceptor driver but nothing is going in?

I would follow the github instructions to run the listener interactively and get 'that' working before trying to go A-Z and doing so under weewx

[Mark Sanchez]

Yeah. I think that's the problem is this is way over my head. I'm not understanding exactly what files to edit in which manner. Oh well. It was fun while it lasted (not really). I guess I'll just get my data from Ambient Weather and consider this one a failed experiment like all other Linux experiments for the most part.
