I am using a Ubiquiti Unifi Dream Machine Pro and most of my network is Unifi. I have been able to set up UD Mobil, my portal is correct now, wifi and wired working to the Eisy. Yesterday PG3 would not allow login but since I got things working in UD Mobil (I think) I have not tried PG3. Will try later today.
I just now tried PG3 and was not able to login. It flashed up the portal login screen (which I logged into) and then flashed up the PG3 login screen. I tried the default passwords and other associated passwords but no luck.
I will keep watching the forum and continue to experiment as I am not in a rush. My ISY994 continues to function well.
