Feed data to PiAware in AVR Format from External ADS-B Receiver

Normally you should be able to use dump1090-fa as a relay for the data.
But you can’t modify the main dump1090-fa configuration file on a piaware sd-card installation.
So you need to run a 2nd dump1090-fa for which you can change the settings.

Edit: For piaware sd-card you can run a 2nd dump1090-fa independently, for example with combine1090:

GitHub - wiedehopf/combine1090: Combine data from multiple ADS-B receivers into one readsb decoder / tar1090 webinterface

Install it and open the configuration as shown on the github page.

Change the target to localhost:29001
TARGET=127.0.0.1:29001

Modify source and port accordingly to where your microadsb receiver is offering AVR data.
SOURCES=192.168.2.44
(Ip address where your microADSB is offering data
PORTS=30002

Make sure the settings are active:
sudo systemctl restart combine1090

Point piaware at localhost:29005 for the beast data.

sudo piaware-config receiver-host localhost
sudo piaware-config receiver-port 29005
