It is indeed but with a twitch I'm still using 2 different PI's, one with the FA image, another with the ADSBX image. I followed James's instructions in the thread announcing the ADSBX image. I tried feeding everything with a single PI yesterday, but ADSBX messed up with FA (both using lighthttpd on the same port). P.
If you want to use FA image use Dan's custom image that feeds ADSBx as well. That should work without issue. Sorry FA takes over images and does bad things. https://www.adsbexchange.com/forum/threads/new-piaware-3-5-3-image.618956/
