Help Please - CAME Garage Door Remote - TOP432

[B Rabbit]

Hi all,

I currently have a working rtl_433 setup using a rapsberry pi and SDR dongle, see attached screen shot of the terminal output. I mainly grab temperature data from some sensors. This was set up about 4 years ago.

My next project is to grab the data from my Came garage door remote, which I thought might be fairly tricky. but then I found this feature request: (https://github.com/merbanan/rtl_433/issues/1452) by @psa-jforestier, so it seems it might be easier than I thought.

However upon testing, I cannot seem to read any of the data from the came remote.

I have a couple of questions please, and thank you in advance for your help. I am still very much learning.

1.   I assume I might need to update my version of rtl_433 on my raspberry pi, as the version I have is probably older than when @psa-jforestier created the decoder. How do I update my version of rtl_433?

2.   Do I need to do anything with this specific config file? (https://github.com/merbanan/rtl_433/pull/1474/commits/16482e153fd9b9a6bf2166fdd1cd00fc9f6a6193) I thought I might need to download it and specify it when running rtl_433? but maybe it is built in to the latest version of rtl_433?

Thanks in advance.

You can just paste that flex decoder in your main conf file, or load it as additional conf file ( -c ) or just put it on the command line ( -X ).

We have binaries at https://github.com/merbanan/rtl_433/releases -- just try out which OpenSSL version you need. Just unpack and run. Maybe copy to /usr/local/bin

Keep the rtl-433 package installed for the dependencies.

Thanks for the quick reply @Christian Z. Really appreciate your help.

I did manage to update my version of rtl_433, so am now running the latest with most recent decoders. Sorry I feel a little silly for not knowing how to upgrade it!!

Not having much luck sorry with pasting the contents of CAME-TOP432.conf into the main config file, or using the -c command:  rtl_433 -c /usr/local/etc/rtl_433/CAME-TOP432.conf. To be honest I am not exactly sure where the main rtl_433 config file is?

I have had success by using the -X command though, see attached screenshot.

Can anyone please provide guidance/advice on how I can correctly load the CAME-TOP432.conf file? or add it to my main rtl config file?

This is probably a silly question, but why is the "CAME TOP 432 Remote" not listed on the main page (https://github.com/merbanan/rtl_433) under supported device protocols?

Thanks again.

That log screenshot shows you the the location's it is looking for a configuration file 

At. Once you find the conf file, just ad the last portion of the came conf to 

The rtl_433.conf

Thanks pdx,

I have checked the three locations listed for a config file and could not find one. So i decided to make a brand new blank rtl_433.conf config file and just pasted the contents of the CAME-TOP432.conf file into the new rtl_433.conf file. i.e. the only thing in the rtl_433.conf file is the config from the CAME-TOP432.conf file.

Unfortunately this did not work for reading the CAME remote control. 

It did however give feedback that is was using the newly created rtl_433 config file. see attached pic. So that is something at least.

Is there anything else I should try?

Thanks.

Michael is correct, older versin would have shown the conf paths. But recent version removed this output due to user demand. Find the paths listed at the top of the help text ( -h ), e.g.

rtl_433 -h
rtl_433 version 24.10-19-ge4546052 branch master at 202412181034 inputs file rtl_tcp RTL-SDR SoapySDR with TLS
Generic RF data receiver and decoder for ISM band devices using RTL-SDR and SoapySDR.
Full documentation is available at https://triq.org/

Usage:
  A "rtl_433.conf" file is searched in "./", XDG_CONFIG_HOME e.g. "$HOME/.config/rtl_433/",
  SYSCONFDIR e.g. "/usr/local/etc/rtl_433/", then command line args will be parsed in order....

...

There are full decoders (write in C source code) that are listed and then there are flex decoders which anyone can change and tune as needed which are not listed.

Okay thanks very much for the information everyone. Your help is appreciated.
