[Wifi75]

Hello I folow this line 

https://github.com/weewx/weewx/wiki/sdr-rpi-recipe 

for install all 

but when i try this commad 

sudo rtl_433 -M utc -F json -G

i have this error:

please see the 'troubleshooting' section at the end of the guide.  it shows you how to blacklist the driver.

I try to send follow command:

sudo modprobe -r dvb_usb_rtl28xxu
echo dvb_usb_rtl28xxu | sudo tee /etc/modprobe.d/blacklist.conf

Now... after send sudo rtl_433 -M utc -F json -G

then i send status command of my weewx service:

I don't know what can I do to fix this issue

hello someone can help me?

What error message did you get? We need more than "But not work"

NB: Take a look at the troubleshooting section at the end of the Wiki. There was an error in the blacklisting command. Be sure to unplug your device, then try the new commands:

# ensure that the rtl kernel module is not running inappropriately
sudo modprobe -r dvb_usb_rtl28xxu
echo 'blacklist dvb_usb_rtl28xxu' | sudo tee -a /etc/modprobe.d/blacklist.conf

ok now work, but i try to find data

i send this command sudo rtl_433 -M utc -F json -G

but maybe my WS1041 work at 868mhz...

it possible scan this frequency?

According to a google search WS1041 transmits @ 433 MHz, but I don't think rtl_433 currently decodes the WS1041. Do you if this WS is a clone?

i dont't know if is clone....

Is the WS1041 console (which should be receiving data) located by the Pi?  If not, do you have Gqrx or some other SDR software installed to see if the SDR is actually receiving a strong enough signal from the sensor?

[Wifi75]

Hi, console is not connected t raspberry, but receive data correctly of cource.

at the raspberry is conneted only dongle usb SDR. 

I use raspberry withoud GUI, 

It is possbile install sam scanner with remote controll from the web ?

[Wifi75]

my system is this:

https://it.aliexpress.com/item/rf-433mhz-wireless-solar-weather-station-PC-clock-radio-controlled-WS1041/32480036686.html

I think it is 433 mhz, but after the scan finds only another internal receiver, I recognize it from the temperature.

if you tell me that ws1041 is not compatible, abandon the project.

 “Hi, console is not connected t raspberry, but receive data correctly of cource.”  You are saying the console is receiving data from the external sensor. 

There are a couple possibility on how to proceed before giving up on this project. 

1.  SDR Approach

a.      If you want to use the SDR, you should install software such as “Gqrx” on the RPi to see if the SDR is actually receiving the 433.7 MHz signal (https://fccid.io/2ANQU-WS1040) from the external sensor.  If you cannot see the signal, try moving the RPi to different locations.

 

b.    If you can see the 433.7 MHz signal from the external sensor, refer to https://github.com/merbanan/rtl_433 on how to record / analyze / provide a sample of the signal.

 

2.  USB Approach

a.    Need to figure out if the WS-1041 is a clone of another 433 MHz Weather Station.

 

b.    If it is a clone, connect the Console to the RPi by way of the USB connection and use that driver if available.  http://www.weewx.com/docs/hardware.htm

Doing a little searching the WS-1041 might be a Fine Offset clone.
