Re: [weewx-user] Weewx + Davis Vantage Pro2 (WeatherLinkIP): intermittent communication issues

[Ryan Stasel]

 I have had occasional issues with connections being dropped to my WLIP. Never been able to figure out why (it’s extremely inconsistent. Sometimes it’ll happen multiple times a week, but recently it’s been well over a month since an issue). Nothing else talks to it. I ended up installing the heathchecks.io weewx extension (https://github.com/uajqq/weewx-healthchecks ) so I get alerted if weewx has been dead for 4 hours so I know to restart things. Sadly the WLIP itself has no real logging to determine if it had an issue. Oh, one thing of note: don’t have batteries in the receiver when using the WLIP. Think I saw that somewhere. Guess if the power to it goes out, you want it to actually shut off rather than try to run off the batteries.  On Aug 23, 2025, at 05:59, Rodrigo Scuissiato <rgu...@gmail.com> wrote:  Thanks, guys! I’ll try disabling all other transmissions to other sites, set up a dedicated VLAN for the datalogger, and give it another shot.

Another point : by default, the datalogger is set to send periodically its data to weatherlink.com, and that can cause conncetion conflict withs weewx. Connect to your datalogger with your browser   : http://aaa.bbb.ccc.ddd    where aaa.bbb.ccc.ddd is the ip addresse of the IP datalogger and verify that the upload to weatherlink.com is disabled - see attached image.

Peter Nock did the actual port.  One thing we've learned through the years: the WLIP works reliably only on LANs. Is the connection between the WLIP and your computer straightforward? -tk On Fri, Aug 22, 2025 at 6:14 AM Rodrigo Scuissiato <rgu...@gmail.com> wrote: Hello, I have a Davis Vantage Pro2 with IP datalogger.
