OREGON WMR 100

[aussiewmr]

Hi Steve,

I have a WMR200 and would be very keen to assist with any testing.

Also - have you had a look at the source code for the "Weather Station Data Logger Project" http://sourceforge.net/projects/wmrx00/?

It only supports real time logging, but it would be a start. Processing the data logger records would be great if you can manage it along with exporting data automatically to a SQL data base like MySQL (not asking for much am I!).

Anyway only too happy to help

Cheers

Thanks, I hadn't seen that. They do say they got their info from the same place as me - the WMR200Reader project - but I'm sure this source code will be useful in addition.

I'm hoping to be able to include that.

along with exporting data automatically to a SQL data base like MySQL (not asking for much am I!).

Cumulus 2 stores its data in an SQLite database, if that's any use. There are licensing/cost issues with using MySQL. Well, there might be. Sun want me to open an account and talk to its sales people about using MySQL with Cumulus, before they can invent a price, so I told them where to go.

Wow I did not know MySQL was not free, well I have just changed my mind about using it then. Is that because you are Donor ware? I would have thought providing an external data export did not warrant you having to pay licenses fees to Sun.

I have a existing weather site that grabs data from a Lacrosse 3600, and have about 2 years of data in MySQL, and I was hoping to export the WMR200 data to it for data continuity reasons.

BTW - what language have you written Cumulus in?

It's dual licensed, GPL and Commercial. Cumulus isn't GPL, so I'd have to have a commercial licence. To talk to a MySQL database, I'd have to use and redistribute the MySQL client library, hence the need for a licence.

BTW - what language have you written Cumulus in?

Cumulus 1 is Delphi (Object Pascal), and Cumulus 2 is a .NET WPF application in C# and XAML.

Hi Steve,

Oh well - then maybe I can import my existing MySQL data into SQLlite to retain the data. I haven't tried Cumulus yet because my station will not talk to Cumulus, how far back in history can the graphs etc go?

C# - good one, the WMR Logger software will be very useful then (for the WMR200 protocol).

I had a look at it and it is reasonably straight forward but they don't support data logging. But I believe once the WMR is connected and first communicated to it just sends data log packets with the live data until they are all logs are sent.

Finger crossed.

Well, many months have gone by and I guess no protocols from Oregon? I was thinking of buying the WMR100 but not if it won't interface with the excellent Cumulus software.
I'll keep an eye on this forum.

I think it's highly unlikely that Oregon will ever give me the protocol. But there's the reverse engineering done by others which should enable me to do the WMR100/200 support one day in the future.

That a real shame, As the Oregon WMR 100/200 is the only real affordable successor to the much loved Fine Offset/Watson/Maplin W8681/WH1081 and all other variants.

It offers all the Davis does as regards to UV Sensor & Data Accuracy but without the High Price Tag -- IF this Station could be supported, I would upgrade to this.

Im sure many more members would follow suit.

An Update:

Would this be of any use to you Steve - http://wmrx00.sourceforge.net/ - In getting the USB Protocol for the WMR 100/200 Weather Stations?

[steve]

Yes, someone posted that link here a while ago. And I do have another source for some of the protocol, which is why I said: "But there's the reverse engineering done by others which should enable me to do the WMR100/200 support one day in the future."

Oh -- Sorry Steve, Should of searched the forum first
I see -- I understand.

I am currently racking my brains trying to decide out of the currently supported Davis Stations and Oregon Stations which would make the most affordable and worthwhile upgrade.

I have the Davis Vantage Pro & Vue, Oregon WMR 928 (Currently cant find anywhere to buy ) and thats around it.

The Vue (with the required Weatherlink) isn't a great deal more expensive than a WMR200, and I suspect will have much higher accuracy.

Okay -- Thanks Steve

The Davis Vantage Vue will me making its way to the Future Plans and Donations Webpage tonight

I suspected it would be the Vue -- A Nice Unit, I look forward to getting it, especially for the Accuracy, Forecast Detail (If it gives the same as the Vantage Pro) and its build quality.

Thanks again Steve

Here are some specs for comparison:

Wind speed update rate: Vue 2.5 secs, WMR200 14 seconds.
Wind speed accuracy: Vue 5%, WMR200 10%
Barometer accuracy: Vue 1 (one) mb, WMR200 10 (ten) mb
Temperature accuracy: Vue 1 F, WMR200 2 F
Humidity range: Vue 0 to 100%, WMR200 25 to 90%
Humidity accuracy: Vue 3 to 4%, WMR200 5 to 7%

Thanks Steve -- that confirms it, The Vue is for me

The Watson W8681 has been a good starter station, but Its showing its accuracy and some elements are troubling...... So hopefully a Vue will be here very soon.
