help with how to use

[rpibkm]

Hi. I am using this program thanks to the video posted by Jeff Geeling yesterday. I have a Raspberry Pi 4B. It is very nice to be able to capture the readouts from the Outdoor Sensors with my computer as a digital file.
My questions are:

1. where is the configuration file (rtl_433.conf) located in my system? Cannot find it.
2. why the output is in triplicate (3 times for each sampling)
3. how do I specify to take samples every 30 minutes for 24 hours and append results to a file?
4. the results from RTL-433 do not match what I see on my device's screen (AcuRite 02074 / 02077) because I calibrated the unit. Therefore, I would like to specify that Temperature should be Sensor temperature minus 2 degrees celsius, and Humidity should be Sensor Humidity plus 5%.
   I think this is all for now. Thank you in advance for your help.

It should be Jeff Geerling.

1. rtl_433 -h shows the possible config locations near the top.
2. if a signal is sent multiple times then rtl_433 will show it multiple times. "what we hear is what you get" ;)
3. samples of what?
4. similar to 2. if you need post-processing try adapting a filter script to your needs, see e.g. https://github.com/merbanan/rtl_433/blob/master/examples/rtl_433_custom.py

Thank you for your very quick reply !!
Question #1 - I already looked into those locations, but the config file is not in any of them.
Question # 2 - okay. It makes sense. I did not know that the signal was sent three times.
Question # 3 - I call "samples" or "sampling" to each of the readings that RTL-433 takes from the sensors.
I would like the signal to be copied (appended) to a file every 30 minutes for 24 hours. Or the frequency (how many times) I choose.
Question # 4 - that is beyond me, but thanks anyway. Maybe at a later time.

There might be no config file by default, you can copy one from https://github.com/merbanan/rtl_433/blob/master/conf/rtl_433.example.conf but pick (the button that says "master") the one that matches your version of rtl_433

You can only log all messages, there is no filtering in rtl_433.

OK. Very good. Thank you for your helpful comments. I think these answer all my questions.
