I basically operate several ADS-B sites, recently I have a cloned a working SD-card. Probably for this reason the site selected at site 2 is the site-url for the first location. How can I make sure that the site-url from /run/piaware/status.json points at the correct location and is not a duplicate?
To answer my own question:
Edit /etc/piaware.conf add a line with feeder-id equal to Unique Identifier from My ADS-B.
