SDR recognized, but no decoding of signals

[linuxus]

Hello,

I've reinstalled rtl_433 from the AUR today because it didnn't decode signals for some reason. Unfortunately, it still doesn't decode anything although I can see the strong signal of my weather station in Gqrx and I tuned rtl_433 to that frequency.
I'm using a Manjaro system and my SDRs are the DX Patrol MK2 and the NooElec NESDR Mini 2. I don't remember if I was already able to decode signals with the second SDR, but with the DX Patrol MK2 it always worked flawlessly in the past.

Does anyone know what might be the problem why rtl_433 doesn't decode signals in my case?
Thank you for your help in advance!

Try different center frequencies and sample rates. See https://triq.org/rtl_433/ANALYZE.html

But how can I now disable these messages?:

sample rate too low for protocol 198 "EnOcean ERP1" 
Current signal level -19.0 dB, estimated noise -24.1 dB

Estimated noise level is -25.7 dB, adjusting minimum detection level to -22.7 dB 

Don't enable features you don't need. You enabled protocol "-R 198" and stats with "-M level"

 

Now it also shows the data in this format as well as in the colored format:
{"time" : "2022-01-08 19:30:53.157938", "protocol" : 25, "model" : "GT-WT02", "id" : 94, "channel" : 1, "battery_ok" : 

Don't add "-F json" if you don't need it.

I started rtl_433 by running "rtl_433 -F kv" because that option delivers the normal output that I was  used to from former versions. But in addition to that it outputs lots of other data

That might be from settings in a .conf file that got installed. Watch the first lines of output for the path, then change the options in the .conf file.

When I set the the variable "verbose" to 0 and put an # in front of the report_meta entries that doesn't help either.

Delete the whole file. It's just an example and obviously not the one you want.

I made an easy video to follow to demod this signal. Use it to double check your rtl433 data. https://youtu.be/jUv9Ib1c6LM

Very nice and easy walkthough!

Thank you for creating that video! As I've already mentioned in one of my previous messages I could solve the problem by installing the git version. Now it's all about getting rid of these noise level messages.

When I delete the config file, I can't receive anything anymore.

Did you have a center frequency setting in there? You can also use e.g. "-f 868.3M" for that.

Yes, 433.975 MHz.
