Testweatherstation

[Ellastonepaul]

This is my first attempt with Python...so please bear with me!

I have a Bresser 6-in-1 Model No 7002570 which I would like to connect to a Raspberry pi running Python 2.7.16 and upload data to WeatherCloud.  The User Guide is excellent, and I used the "Easy Installation" approach but I seem to have fallen at the first hurdle, the "Testweathertation" fails.  I am not sure if it is an error in the USBlib (I followed the Dependancies notes and libusb1 seemed to load OK) or whether the console is not recognised.  The error log is attached. Any guidance would be welcomed.

Thanks

pywws-testweatherstation

The error is LIBUSB_ERROR_ACCESS, which could be a permissions problem.
As it says in the documentation, try running pywws-testweatherstation as
root (use sudo).

However, the Bresser 7002570 looks nothing like the Fine Offset stations
that I've seen before, and it doesn't seem to use EasyWeather software,
so I don't expect it to work with pywws. With it plugged into your pi
use the 'lsusb' command to see its ID. If it's not '1941:8021' then it's
not a pywws compatible station.

Jim,,

Thanks for prompt reply.  It was not looking hopeful but, as suggested, I have checked the ID and got the following

ID 1941:8021 Dream Link WH1080 Weather station  which is OK?

Bresser do supply  Windows Sodtware branded Weather Tool. It can be found at https://bit.ly/2L36v30 Is this of any help?

Thanks again

,

Thanks for your prompt reply. Fearing the worst  I checked the ID, as you suggested, and got the following

 

ID 1941:8021 Dream Link WH1080 Weather Station.   which seems a little more hopeful.?

Bresser do supply software branded as Weather Tool.  It can be found at https://bit.ly/2L36v30 Does this help in anyway identifying the appropriate drivers?

Maybe. Given that they reused the USB ID of a toy missile launcher for
the original weather stations it's possible they would keep the same ID
even if they totally changed the rest of the software.

Not really, unless you want me to boot up an old Windows machine,
install it, then test it with my weather station.

It might use the same USB communications as EasyWeather or it might not.
Your station either works with pywws or it doesn't.
