Hi m0euk
At home I can connect either way, or remotely via de RPI4, directly via my local router and also on the web server (cloud.eesdr.com:5450).
The direct connection is the more convenient as it has a minimal delay. The connection via de RPI4 is also very fast, as it links rig and laptop directly (showing the lightning sign in the status bar; see the manual). The web connection is only for listening and has a significant delay, but works fine for listening.
I have checked the remote connection when being away from home (still no farther than 25 km) and it works very well.
BUT, I have not checked transmission yet, as I don't have en E-coder for CW for my Mac (too expensive).
In summary, everything works fine as explained in the manual.
I hope this helps.
