I would like to try to set up speedfusion so I can take advantage of the hot failover functionality.
The two WAN`s connected is a starlink dish over WIFI-WAN and a SIM. can someone explain what this remote ID is, and what I need to put in there?
Sounds like you are wanting to use the SF Connect service that Peplink offers. The following video is a little dated but will show you how to set it up:
It is now shown as SF Connect on the device dashboard, not SpeedFusion Cloud.
That is what I wanted to try yess! But upon seeing that the subscription fee for it is 800 USD pr year, I think I`ll rather hold my horses 
There is so much more fun things to do in life with that kind of money, than having a bit of a better internet connection.
