Davis Weatherlink IP with weewx AND upload to Davis !! ??

[Phillip Pacier]

Good day, all!  I have just run across this wonderful piece of software, and it may just be the e-ticket I have been looking for.  I have been uploading my weather data to my local NWS office for a decade.  They now prefer to mine the data directly from the Davis weatherlink web site.  Fine - that works great.  However, I miss my local data.  When running a Windows server, I ran WeatherDisplay.  It had an option, when being used with the weatherlink IP logger, to drop the connection to the logger every minute, which would then allow the logger to push the data on to Davis like normal.  In effect, this would eliminate the requirement for the "Upload Data to Davis" box to be unchecked.  I was trying to get this to work with wview and it doesn't look like anyone is interested.  Is this possible?  Thanks in advance!

Hello, Phillip

In theory it would be possible. I'm imagining that every loop and archive event would result in a RESTful push to the Davis site.

But, there are lots of speedbumps along the way. For example, the Vantage protocol is very stateful. Right now, weewx manages that state, but I can imagine that the Davis site would want to as well. Arbitrating that contention would be a challenge.

It sounds like WD gets around this problem by simply abandoning the console every once in a while and letting it communicate directly to the Davis site. I suppose weewx could do something similar, but it would not be, umm, "natural." 

The lack of enthusiasm in the wview community may be because the Davis site uses a protocol better suited for a device driver than for a web application and its lack of elegance does not inspire anyone to give it a go. But, that's just my opinion.

In any case, give it a try. Weewx was designed for experimentation. This one may be a bit more of a challenge because it messes with the internal state machine in weewx, but it doesn't sound impossible.
