I have been using this system for a few weeks now and must say I am very impressed with the reception especially compared to my earlier set up. One thing that I have not been able to do achieve - when viewing my Pi Skyview is it possible to view other feeders on the same map?
If i understand your question correctly, no you can’t.
The data you are viewing is local to your network.
If you have a buddy though and he were to expose the beast data for example by opening a port on his router and using dyndns for a web address, then you could use something like this: https://github.com/wiedehopf/combine1090#combine1090
Equally if you own multiple receivers you can view them in one map this way.
A better solution is probably to use a VPN or something instead of exposing the beast data to the internet.
Many thanks for your reply and explanation. Much appreciated.
Add own receiver
And add data-feed-from-adsbexchange
