Non supported weather station

[Ivan Schrooyen]

Hello,

I would like to use Weewx to process the waeather data from my personal weather station.

This station (Bresser) is not supported by Weewx, but the data is transferred to Wunderground (table).

So, I am wondering whether it is possible to get the data from there, process it and send it to another form of website/app?

Thanks in advance,
Ivan

Which Bresser model? Some are Fine Offset clones. 

It is possible to "import" data from the Weather Underground, but it is a single-time, batch process, not intended for continuous use.

Hello Thomas,

Thanks for your answer.

The model that I have is the following. I did not see any possibility to export the data to something else than wunderground.

https://www.bresser.de/fr/Temps/BRESSER-Station-meteo-couleur-WIFI-avec-capteur-exterieur-5-en-1.html 

Please let me know if I am wrong, this would help.

Also, what I intend to do (even if not super clean), is to run a python script from my NAS every 60s.

This script would check on wunderground if there is new data online compared to the text file stored on the NAS.

Then it would update the text file on the NAS. Then use this text file to update a graph available on a website/app.

Not sure yet whether this is simple or not...

Is there any easy app that you suggest to use?

Thanks in advance,

Ivan

I doubt if you will find wunderground to be reliable if you try and access it to get your data every 60 seconds!!!!  Wunderground is just not designed for such usage.

Hello Andrew,

Is there a cleaner way to get my data out of my weather station then?

I am open to any suggestions...

Interceptor perhaps so that weewx intercepts the data on its way from the station to wunderground .....

The  Bresser 5in1 Weather Centre is now supported by RTL_433 so another option is to try RTL-SDR.

Hello Gary,

Thanks for your answer! I am still looking for a good option to get the data on my NAS.

I am not sure I understand what you say about RTL_433 and RTL_SDR, could you please explain with a bit more details?

Is it possible to catch the flux of data with simple python programming or will it be complex?

Is there additional hardware required?

Thanks in advance,

Ivan

No Bresser station model is a Fine Offset clone. These are two separate manufacturers, they are not resellers.

Resellers like Ambient and Froggit sell both Fine Offset and Bresser stuff.

Hello,
Sorry to be back on this post...
In the last couple of months, I have tried a couple of things based on Wunderground, and it's indeed not reliable for continuous usage.

So, I am back to the original idea, which is to:

1) install weewx on a raspberry pi and intercept the packages sent to Wunderground

2) get the raspberry pi to add new data in the mysql database hosted on my NAS

Can anyone confirm whether this will be possible or not?

The part I don't understand is "what does it mean that my station is not supported by weewx"? As the flux to Wunderground is standardised, and this is what I am trying to catch... A clarification there would help.

Alternatively, Bresser sells a station able to send the data directly to whatever URL, but that means replacing the weather station...

Thanks in advance,

Ivan

a simple google search shows that many people have decoded the 433MHZ signal from this weather station.  would be a simple matter to build a received with some code to decode the signal. once you do that adding the data to weewx is trivial.

Another approach is to use the interceptor driver. It intercepts posts to the WU and, instead, runs them through WeeWX.

To add to Gary's post on using an SDR solution I know that the Bresser 6 in 1 is supported by the rtl_433 software, and I'm pretty sure that the Bresser 5 in 1 using the 868MHz frequency is compatible.

However the software for these may not yet be in the main branch - but is available.  See this post:

https://groups.google.com/g/rtl_433/c/M8POHmOuBb0

(The Froggit WH6000 is yet another clone of the Bresser 6 in 1 WiFi.)

An SDR is relatively cheap, and the only downside is that the pressure, inside humidity and inside temperature provided by the console will be missing.

Hope this helps

Bob

Hello,

Indeed, I would prefer the interceptor plugin in order to access all data (including pressure).

I have finally (after significant efforts) installed Weewx directly on my Synology NAS.

I have not tested it much yet, but I have the impression it runs.

Now, I am trying to install the Weewx plugin, but the instruction says the command line is:

sudo wee_extension --install weewx-interceptor.zip  

While you can imagine on Synology I get the error:

-ash: wee_extension: command not found

I know this highlights my clear lack of knowledge, but could you please advise me on how to adapt the command line to my config?

Thanks in advance,

Ivan

Indeed, quite a silly request ;-)
Thanks a lot for your patience, it really helped!

I got a few steps closer, and getting excited now!!
