Multiple radios in Home Assistant

[Bill Ostrander]

Hello to all,

I am currently running RTL_433 as an add-on in Home Assistant (https://github.com/pbkhrv/rtl_433-hass-addons/tree/main/rtl_433) and have several SDRs connected to a single machine that I am trying to read traffic on different frequencies (319.508M & 916.8M) without having to hop frequencies.  I have been able to each of these devices to work on their own frequencies and publish into MQTT when used one at a time.  Below is system information as I often see people asking for that to better assist.

arch: amd64

channel: stable

docker: 20.10.9

machine: generic-x86-64

Home Assistant OS 7.5

supervisor-2022.03.5

core-2022.3.7

The system set up is an HP intel machine with i7-10700 CPU with 32GB ram, with HA running off a 500GB USB SSD (as boot system and not in VM).  The machine boots from this drive on startup while I wait to get an internal SSD so that I can keep the original Windows 10 drive and setup in case I want to revert that back.

I have two configuration files in rtl_433/

- rtl_433.conf.template

- rtl_433_2.conf.template

I have tried adding both of these in the config tab of the add-on but gives an error and defaults to add-on settings, separating the two files by a comma as well as by | , both of which give an error.

You'll likely need to ask at pbkhrv/rtl_433-hass-addons, if it's about that programs parameters.

I've tried this before and was never able to get it to work.  I finally ended up putting each SDR radio on a separate Raspberry Pi.

I've tried this before and was never able to get it to work.  I finally ended up putting each SDR radio on a separate Raspberry Pi. 

At least for rtl_433 it should "just work". With RTL-SDRs use rtl_eeprom to name the devices (e.g. "SDRAT868"). Then use those names in the respective configs (e.g. -d :SDRAT868).

[Jason White]

 I concur. I have three SDRs on the same Pi 4 and simply refer to them as device 0, 1, and 2 in my config file:

[...]

device 0

[...]

I don't recall exactly how I figured out which one was which other than some trial and error.

Regards,

-Jason
