Hi,

After countless hours of coding, Wiresharking, and help from A.I., I’ve put together the first working version of a WeeWX extension called wlip-emulator.

It’s written in Python 3 and emulates a Davis WeatherLink IP device, so other weather software can connect to WeeWX just like it was a real WLIP logger.

So far it’s only been tested with a Davis Vantage Pro2 using a USB datalogger running under WeeWX. No other setups tested yet.

Multiple clients seem to work fine — I’ve tested two WeatherCat instances connected at the same time without issues.

I have in past used virtualVP and after changed to WeeWX and linux I missed to get data also to WeatherCat. Now, I can get it again.

Project is on GitHub:
👉 https://github.com/iiseppi/wlip-emulator

Known limitations / Status
   •   History download is not implemented yet
   •   Tested only with VP2 + USB logger
   •   Other Davis models and serial loggers are untested
   •   WLIP protocol support is partial and still evolving

Feedback, testing on other setups, and pull requests are very welcome 🙂

Pretty cool.  I submitted a PR to them so it can be installed/uninstalled via the extension installer.

Thank you for PR Vince.
New version uploaded, with history download and support for more weather software. 
More testing is needed. :)

Hi,

Newest version supports installation through weectl command and does not require Davis weather station at all.

Hello,

This may be just the extension for me.
Will this only send archive or will it also send loop?

Hi,

Yes, it is sending loop data also.
