xAP

Great application and great forum!

For years now I've been using 1-wire for my weather sensors; specficially the AAG anemometer. I never really was happy though with the wind speeds I would see (even after modifications). It seemed to be an inertia thing or debounce on the sensors thing. I continued though to use it over the years purchasing a second one and swapping them out every 3-4 years. That said I have extensive 1-wire networks configured. (3 9097's and 3 Temp08's). I use both direct connects and XAP to get data. (IE: using HB counters today for rain tipping bucket, two water meters, lightning sensor, etc). Outside I have multiple combo (temp/light/humidity) sensors that I utilize.

Been posting on WUnderground for a few years now.

Recently getting ready (already started) testing the "Open Offset" and the "Davis Vantage Vue" weather stations. I mounted the "Open Offset" in a place to test yesterday about 4 meters off the ground. The permanent location is kind of difficult to get to so I want to wait a bit. (its on the roof and easy to climb up; but I have to slide down the pitch of the roof to the ladder to climb down - no fun).

I have enabled XAP on the Cumulus application and getting data from the "Fine Offset" to USB to Server to Cumulus. I see the data fine.

I am just wondering if I can change the way I get the data in the XAP package? Maybe get outdoor humidity? And maybe get the Rain counts in inches versus cm?

Unfortunately, the xAP format is 'hard coded' into Cumulus. Originally, I thought I was following some sort of standard, and then I was asked to add rainfall, but the "standard" didn't seem to cover this, and I was basically told to make something up. I could do the same for humidity at some point - but perhaps the way to go would be to allow the format of the message to be overridden using a text file containing web tags (in the same way that the default Twitter message can currently be overridden).

Steve,

Thank-you for the information.

Yeah; as far as I know the XAP standards have been kind of "loose". I like that I get all of the data (most of it) from one XAP message versus one device one sentence (or xap message). I can do the conversion live from metric to decimal as I do that today before inserting it into the database.

Here's just one device and one sensor on the one device. Its gets a bit hectic with multiple devices.

}

I also utilize XPL which is kind of similiar to XAP only less rules and not used as much. I do two way communications with it though; building "events" which either poll or control hardware. IE: I run a python script / xpl/xap hub on a touch screen which run hardware stuff via the network "mothership" events.

I'm looking to "offload" the weather station / software from the mothership server to your application as I am kind of pushing it with 18 serial / 3 USB devices, about 700 or so variables and like maybe 400 events. IE: I have temperature and humidity sensors in every room in the house - just I guess because I could do it and its nice to see the differences in the temps, etc.

Thank-you for such a great application there Steve!

Attached is a snapshot of one of the touchscreens. I also do weather alerts; when one comes up from NOAA the screens go to a combo weather alert page, cam pictures and scrolls the NOAA weather alert on the bottom of the page. The screen is kind of a hodgepodge of flash and elements which are defined variables (like from Cumulus). The WUnderground cam shot is a composite made every 5 minutes or so encompassing web snapshots, radar, graph creation and variable weather instrument variables put together with a script which builds it. Works well and is fast.
