Weewx + Bresser Wifi Station + sdr

[sc.lep...@gmail.com]

Hello 

I am interested in bresser Station  with Wifi support but station base as no usb port to connect to an rpi.

Bresser station like this  : https://www.bresser.de/fr/Temps/Stations-Meteo/Centrale-meteo/BRESSER-Centrale-meteo-WIFI-ClearView-avec-capteur-7-en-1.html

If I buy usb sdr key like here : https://github.com/weewx/weewx/wiki/sdr-rpi-recipe
It will be possible to get packet from sensors ?  

Frequency  :  868 MHz for sensors 

Thanks a lot

The Bresser 5in1 868 Mhz (868.200 in my case) certainly works with a Pi0W and a £23 USB SDR radio bought off Amazon.

Hi ... Please help.... I have Bresser 5in1 7002580.... I am using rpi4 with weewx 4.2.0 and nooelec sdr .... The sdr delivered to weewx the rain_total packet but weewx in my case doesn't make the deltas calculations so the rain is always 0.00mm ... I have tried almost everything in weewx.conf (because i think that something have to trigger weewx to calculate the rain value with rain_total packet ) but no rain ... Only pain ... Both sdr.py and weewx.conf are set up correctly (i think) and i have in the [sdr] field

[[deltas ]]
rain = rain_total
the station sends 2 partial packets ... fisrt has the rain and wind values and the second all except rain

Probably you will notice that in log the station appears like 6in1 .... i dont know why but i modified (with a big help of my friend) the sdr.py and returns bresser5in1.packets.... all the others values transmitted to weather sites without any problem...
