Reading Atlas signal w/Rpi3 and SDR

[Preston]

Hello, So I have tried getting this working and giving up about 8 months ago as the SDR had not been developed enough to read the AcuRite Atlas signals. I have found a renewed interest in trying to get this working again as it looks like people are getting there Atlas's into WeeWx. But I'm running into a different issue this time. I have followed this guide (https://github.com/weewx/weewx/wiki/sdr-rpi-recipe). In that guide hes using matthewwall weewx-sdr driver (https://github.com/matthewwall/weewx-sdr.git). When looking through the change logs it looks like the Atlas was added back in update 0.73. 

When i had tried doing this a few months ago, running:

rtl_433 -G

it cam up with some gibberish,...More or less it couldn't read the signal. If i remember it correctly it detected my Atlas as a 5n1

But now when I run the rtl_433 -G command it does not detect my Atlas at all. It will detect my AcuRite 06002M, so i know the RTL-SDR dongle is working. And i know the Atlas is sending a signal, because my AcuRite access is showing its connected, and its updating the myacurite.com page with the weather stats.

For reference I have the Nooelec NESDR Mini USB RTL-SDR from Amazon https://www.amazon.com/gp/product/B009U7WZCA

Raspberry Pi 3+ with 5v 2.5A Power Supply

What am i doing wrong, How are you guys getting the Atlas to work with your Raspberry Pi's?

Any ideas or things that I'm probably doing wrong?

Does anyone have any ideas on what I could try?

I'd even be will to start from scratch and if someone can point to a different walkthrough on how they got there Atlas to work vis SDR. or even through the AcuRite Access as that's what the Atlas is connected through now.

I had this same problem. You need to use a different version of rtl_433 that was added specifically for Atlas support (and is still under development).

The version you need is on github at https://github.com/merbanan/rtl_433. However, you can't just use the master version -- you should clone and compile the branch called "feat-atlas" (i.e., feature change for the Atlas).

Once you run the proper version of rtl_433 with the SDR driver, you should see the Atlas info in your log and can adjust your /etc/weewx/weewx.conf file appropriately to snag those readings.
