weewx stopped logging

[Ed Wilts]

Everything seemed to be working fine with my weewx/Tempest until mid-February, but now nothing is logging.

The Tempest works fine and uploads to the Tempest website.

weewx appears to be working

weewx is not getting data via weatherflowudp

I've updated everything to current but no luck yet.  Any suggestions as to what I should try?

Thanks!

Run my standalone UDP listener with the --raw option and see if your computer is hearing anything (github link)

Or run wireshark if you know how to do that.  Basically sniff the wire/wireless.

You have the weewx driver set to "share_socket = False" so you will need to shut down weewx first.  FWIW, I recommend setting that True so multiple programs can listen for the broadcasts.

[Ed Wilts]

Thanks Vince,

I did change share_socket to True but have weewx down for safety while I debug this.

Your tool doesn't show any incoming UDP packets.  This just sits there forever, not displaying anything:

pi@weatherpi:~/weatherflow-udp-listener $ ./listen.py --raw

I know I have TCP from the hub because I'm seeing updates to https://tempestwx.com/station/57399/graph/159963/temp/4 (and wunderground) so it's just the UDP bits that aren't working.  But they did work for over 6 months :(

It's not just your tool - I also tested with tcpdump and netcat and both come up dry.

I reconfigured the wireless on both the Pi and the Tempest to use the same 2.4Ghz SSID (my home guest network - my main internal network is both 2.4 and 5 with the same SSID managed by the ASUS router.)

So now that I've demonstrated that UDP packets aren't getting from my hub to my Pi, what can I do?  They're sitting about a foot apart from each other.

Thanks again,

I've never heard of the UDP not working.   Typically the mistake folks make is trying to put the hub on a IoT network and they forget that the weewx box has to be on that network too because they forget that broadcasts don't route. Make sure your weewx/sniffer/listener boxes are really on the same wifi network as the hub. 

If your hub is on the same network as weewx and your sniffer(s) and that doesn't help, then I guess get WF support involved via their forums.

I'm guessing your guest LAN is a different subnet than your regular LAN (?) so you could try 'traceroute -n' to the ip of the hub and see if it's a straight shot or if it's routing through your ASUS router.

But if you have them all on your normal LAN and they worked, and moved them and it broke, it's 'likely' that one box isn't on the same network as the other.

[Ed Wilts]

Thanks Vince - you got me on the right track.  I added a network block in my router to prevent my Pi from connecting to the 5Ghz network and now that they're on the same 2.4Ghz network, I'm getting weather data via UDP again.

Now that it's getting data and it's updating the local web page and my externally-facing website, I just need to get the updates to the weatherpi page on the local display.  I've got the fields on the display but not the data.  I don't know what that's about but I'll work on that some more later.

Thanks again for your help,
