library librtlsdr.so.0 not dound in /usr/local/bin/rtl_433 RTL-Stick does not get Signals library

[feigenmann]

Hi there
I did create the sh script in config/... and configured it the way it works for me.
Allthough when setting up the MQTT node in Node Red an attach a debug node to it not Output is sent from the MQTT node.

I would like to monitor 433 temperatur sensor from renkforce and TFA - i get the following output
without the plugin it worked - but i would like to get it wokring using the plugin

I just fell over this trying to rebuild a working install to get updated decoders...now I have NOTHING working and no way to roll back that I can see. Help?!?!?!

Workaround figured out -- it seems the library is installed inside the addon container under /usrl/local/lib64 but the runtime system is not looking in the usual library locations, I don't know why.

In HomeAssistant via your favorite method (samba, ftp, ssh), edit the rtl433 startup script:
/config/rtl4332mqtt/rtl2mqtt.sh

Find where it calls rtl_433 and add this to a new line before the rtl_433 executable:
/usr/local/bin/rtl_433 -F json -R $PROTOCOL -f $FREQUENCY -g $GAIN -p $OFFSET | while read line

Add a new line BEFORE the rtl_433 line:
export LD_LIBRARY_PATH="/usr/local/lib64"

Now re-start (not rebuild) the addon, and it should fire up correctly.

IMPORTANT -- the new rtl_433 also changed the sensor type names so you probably need to modify all of your mqtt sensor entities to point at the new paths. For example, mine changed from sensors like "homeassistant/sensor/rtl433/Acurite_tower_sensor/1234" now the MQTT path is "homeassistant/sensor/rtl433/Acurite-Tower/1234". Also beware some of the JSON changed, for example "battery_low" (which was a 1 for low and 0 for good) is now "battery_ok" (where 1 is good and 0 is low).

I can confirm that your solution with exporting LD_LIBRARY_PATH works great! Thanks 👍
